A script to convert MATLAB/Octave into TikZ figures for easy and consistent inclusion into LaTeX.

179 Ratings



Editor's Note: Popular File 2013 2015 2016

This is matlab2tikz, a MATLAB(R) script for converting MATLAB figures into native TikZ/Pgfplots figures.
matlab2tikz supports the conversion of most MATLAB figures, including 2D and 3D plots. For plots constructed with third- party packages, your mileage may vary.
The workflow is as follows.

a. Place the matlab2tikz scripts (contents of src/ folder) in a directory where MATLAB can find it (the current directory, for example). b. Make sure that your LaTeX installation includes the packages

TikZ (aka PGF, >=2.00) and
Pgfplots (>=1.3).
Generate your plot in MATLAB.

Invoke matlab2tikz by
>> matlab2tikz();
>> matlab2tikz('myfile.tex');
The script accepts numerous options; check them out by invoking the help,
>> help matlab2tikz
Sometimes, MATLAB makes it hard to create matching LaTeX plots by keeping invisible objects around or stretches the plots too far beyond the bounding box. Use
>> cleanfigure;
>> matlab2tikz('myfile.tex');
to first clean the figure of unwanted entities, and then convert it to TeX.

Add the contents of `myfile.tex` into your LaTeX source code; a convenient way of doing so is to use `\input{/path/to/myfile.tex}`. Also make sure that at the header of your document the Pgfplots package is included:
% and optionally (as of Pgfplots 1.3):
\pgfplotsset{plot coordinates/math parser=false}
There are reported incompatibilities with the following LaTeX packages:

I ran into a small problem while using this (wonderful) code. When the x-axis are labels, say from:

set(gca,'xticklabels',{'this\\is a','char\\label'})

the pgfplot file requires a line like:

xticklabel style={align=center},

to compile the xticklabels with the newline characters (it compiles just fine if the labels do not contain newline characters). matlab2tikz didn't seem to add the required line automatically. Thanks for all the great work!


Does matlab2tikz support saving figures plotted using polarplot function available in MATLAB versions starting from 2016?

I could save figures plotted using 'polar' function, but not 'polarplot'.


Alan Rochford

@Edward Kolanko: Thank you for the kind words. I presume it should be possible to generate an "empty" output document, by adding an empty axis in the MATLAB figure. However, I really wonder why you ask: is there something specific you are after? After all: a plot without contents is like a pub without beer ;-)

This is very very good. I fell in love from the first graph.

I wonder if it is possible to generate tex code without drawing a graph in the figure.

Amazing work! Works perfectly!


Marie (view profile)

This package is great, thank you very much for all the work involved!

Recently, MATLAB changed their syntax for double axis plots, and the command plotyy() is not recommended anymore. When using yyaxis() instead (which is what they recommend) the figure doesn't have two axes objects anymore, but just one.
While matlab2tikz worked fine when there were two axes objects (handles of which could be retrieved with ah = findobj(gcf,'Type','Axes') ), it doesn't display the left-side plot any more in the new format. Could you possibly fix this? That would be of great help to me, thank you!

Deepak Ingole

Dear Egon Thank you very much for your reply.

@Deepak Ingole: That is not an error message, just an informational message. We don't do a proper check on which version of pgfplots you have installed (since that is complicated to do in a platform-independent way). We do, however, check if your plot needs some features from more recent versions, and in that case we adapt that message accordingly.
The check is in there because quite a few people are stuck with an older version, and that way they know beforehand whether LaTeX will choke.

Note that the message reads "you will need pgfplots 1.3 OR NEWER", so you should be fine with 1.14.

If such informational messages bother you, you can add `'showInfo', false` to the parameters to matlab2tikz to suppress those messages (also have a look at `help matlab2tikz`, since there are a few more options to reduce the output to the console).

Deepak Ingole

Can somebody please help me to solve the issue of pgfplots version. I have pgfplots version 1.14 but still I am getting error as follows: "You will need pgfplots version 1.3 or newer to compile the TikZ output."

I tried in MATLAB 2015b.

Thank you.

Hendrik Fuest

Hendrik Fuest

Thank you for the update. I am having a few issues with using the output file:
1. When a stacked figure (an area plot and regular y plot) is output to a .tikz or .tex file, and I attempt to use the figure in a Latex file, all the data points end up in different places than when originally plotted. In addition, the legend disappears, and the orientation that I had set the y-axis label (Orientation, '0') is reverted back to the default orientation of 90.
2. When I try to generate a figure using a general matlab2tikz output figure without any scaling size specified, I end up with a very large figure that extends way beyond the limits of the page. I have to always manually scale the .fig image down to a much smaller image, in addition to specifying a scaling value, (e.g. 'width', '0.5\textwidth') which I did not have to do with the older version.

Jonas Lenz

Great work!

As far as I understood the possibility to add the 'forget plot' option to surf-plots was missing. I just added the following lines to the function 'drawSurface':

if ~m2t.currentHandleHasLegend
  % No legend entry found. Don't include plot in legend.
  opts = maybeShowInLegend(false, opts);

It temporarily fixes the problem but I am not sure if it provides for all contingencies.

Amazing work!

Abhinav Gaur

I am using Matlab 2016b. Strangely, when I produce the .tex using matlab2tikz,

1) the values for xticks are copied and reproduced in the figure instead of those of xticklabels.

2) the fonts is different from what I chose in Matlab.

Can you please direct me to relevant link where I can read about these issues and possibly solve them ?


Abhinav Gaur

amazing work. Kudos


Buana (view profile)

Using it since many years. I really love it. Master or PHD thesis without is not even thinkable.

adam taylor

Great package,
When exporting transparent patches (like from bounded Line for example), the patches transparency is set but the outline is drawn. The following could be added around line 3030 when setting face alpha
opts = opts_add(opts,'draw opacity',sprintf(m2t.ff,0));


@Egon Geerardyn,

I understand...
So far, you did a great job. So, thanks again.

I suggest to other Tikz users who would like to use annotations to manually fix the exact cordonates they need. The following free application may help : GEOGREBRA.

@stefed: We are aware that we do not fully support yyaxis or other new constructs in R2015b/R2016a. You can still try plotyy (unless this has been removed from the last version of MATLAB). To be honest, I have not opened MATLAB in over a month.

@pankaj singh: This is not a problem of matlab2tikz, but rather a fundamental limitation of the LaTeX compiler you are using. Please read the documentation at,-sorry

@Djibril TOGOLA: I had a quick look in the source code regarding the Arrow problem. It was a known problem: this is something we still have to implement.

pankaj singh

@Egon Geerardyn... Thank you.... I was also getting the memory issue problem similar to @ragheb. like.. "TeX capacity exceeded, sorry [main memory size=3000000]". My figure was only 401KB.
Then i used, your suggestion of '0.3g', It reduced my figure size to 203 KB (almost 50%). So it worked for me. Thanks again.

I request author to please improver his code so that larger plots/graphs are converted automatically to the size acceptable by latex.

pankaj singh

u can also use
\pgfplotsset{scaled x ticks=base 10:0}
\pgfplotsset{scaled y ticks=base 10:0}

in the preamble of your latex document to individually adjust the xtick labels and ytick labels...u can change by like 10:1, 10:2, ...etc. as per your required tick values.

pankaj singh

doesnot include the ticks. why ???

@hannes fischer
You would want this setting to remove the thousand separator:
'x tick label style={/pgf/number format/1000 sep=}'

If you have set up more settings for the x tick label style, it can look like this:

'x tick label style={rotate=90,anchor=east,/pgf/number format/.cd, fixed, fixed zerofill,precision=0,1000 sep=}'


stefed (view profile)

Great, but I does not support the yyaxis function, which is new in MATLAB 2016a. Can you make this happen, please?

Juan Reyes

Awesome! Thank you very much.

@Egon Geerardyn, I thank you for your kind suggestion, but I regret to inform you that it doesn't work too. The error remains unchanged :

Warning: Don't know annotation ''.
> In matlab2tikz>userWarning (line 5955)
  In matlab2tikz>drawAnnotationsHelper (line 3079)
  In matlab2tikz>drawAnnotations (line 3024)
  In matlab2tikz>saveToFile (line 519)
  In matlab2tikz (line 362)

The only way I found to fix the problem is to manually add annotations into the tikz file. This is costly because it requires to find the exact coordinates.

@Djibril TOGOLA: I think with the upcoming release (1.1), this should no longer happen. You can already get this version from our develop branch on GitHub ( )

Ivan Abraham

The file does not work with quiver plots. I have been able to reproduce the same error on versions 2014a, 2014b and 2016a. The error is the following:

Matrix dimensions must agree.

Error in matlab2tikz>drawQuiverGroup (line 3661)
    data(4,:) = x + u;

                [m2t, str] = drawHggroup(m2t, child);

Error in matlab2tikz>drawAxes (line 852)
    [m2t, childrenEnvs] = handleAllChildren(m2t, handle);

        m2t = drawAxes(m2t, relevantAxesHandle);

Error in matlab2tikz (line 352)

Otherwise excellent work!

Tests, both Headless and Graphical, fail on a Mac running MATLAB Version: (R2016b) Prerelease.

With the latest version of Matlab (2015b), I find the following bug :

Warning: Don't know annotation ''.
> In matlab2tikz>userWarning (line 5316)

With the previous versions of Matlab, such an error did not occur. So, what do you think about that?

The tool is perfect. Congratulations and thank you!


Beenwa (view profile)

@sreenath M.G.: Thank you for the kind words! If there are recurring nuisances that pop up (or minor modifications that you feel are necessary every time), please do not hesitate to report an issue on GitHub and we will see what can be done about it :-)

"matlab2tikz" does a great job in converting matlab/gnu octave plots to pgfplots/tikz and saves a lot of time and effort. Axes, ticks, labels, grid etc. are perfect in the tikz output. Now there is no need to write the variables to delimited files to plot with pgfplots. Minor modifications are needed before inserting the tikz code in LaTeX. That is always the case if we convert from one format to other. A great package! Thanks to developer(s).

@Matthew Taliaferro: Thank you for the kind words! Currently, there is no support for adding own code at random places in the output. However, there is some support planned (and almost completely implemented) for this to work. You can monitor the progress at

I absolutely love this program, my thesis would be a pain without it. Is there a way to add something like this to the output tex file from a matlab script?

\addplot [color=black,solid,line width=1.0pt,domain=0:1,samples=11]{x+x^2};
\addlegendentry{Eq. \ref{eq:equation}};

Most of my graphs are a mix of scattered data and functional data. Sometimes it would be nice to graph the functional data using pgfplots native graphing utility.

@Stefan Schiessl: Thank you for the kind words! Is there a reason why you would like to see this as a toolbox? A year ago, we have evaluated whether or not to provide it as a toolbox. Back then (I cannot speak for the situation right now, but I assume little has changed) it was impossible to integrate MATLAB toolboxes, MathWorks's FileExchange and GitHub in a decent way (i.e. without storing big binary blob files that may go outdated in our git repository). Back then, this disadvantage vastly outweighed the few advantages of a toolbox (basically: one-click install and distribution). But we are certainly willing to reconsider this decision.

Reliable tool to create fancy plots for LaTeX!

Are you thinking about providing it as a toolbox?

@Jonas: Many of the standard MATLAB properties of lines are translated to TikZ, e.g. if you set the "LineWidth" of a plot in MATLAB, this will add "line width=..." to the corresponding value. If you want to have a more low-level access to tweaking the TikZ code (e.g. things for which there is no MATLAB counterpart), in a future release this will be included. There is already an experimental implementation at which works quite well.


Jonas (view profile)

Is it possible to add a property to addplot? Sth like

addplot[...,line width=2pt]

line width=2pt

automatically without reopening the tikz files??

@Lairenlakpam Joyprakash Singh: Please report future problems on our GitHub. In this case, there are a few errors with your code: the value you provide to 'floatFormat' is incorrect, it should be something like '%0.3f' or '%0.3g' instead. Also, it is recommended to put the filename as first argument, not as the last one). This has not changed since old versions: the float format has been like that for years.

Thanks. I got it after I read the article at,-sorry

It works when I use LuaLaTeX. However, using of other commands like cleanfigure() as well as matlab2tikz('floatFormat','%0.3','myfile.tikz') did not work as later plots only axes [no waveform].

My MATLAB code was:
%wavplay(signal,Fs); % for Windows based machines
sound(signal,Fs); % for Mac based machines

Jun Liu

Very useful and working very well. Well done! Really appreciate that the developer has kept it update.

@Ingrid: it's currently not possible to pass different parameters for different subplots. I see a few solutions for your problem:

(1) I think it should be possible to call cleanfigure by passing an axes handle instead of the figure handle. So if you call cleanfigure for each subplot using different parameters, that should do the trick, I think.

(2) If the above does not work; split your subplot over different figures, run cleanfigure on each plot, and then recombine those plots as subplots in one figure (there are some functions on FileExchange and StackOverflow that help with those steps).

(3) In the develop branch on GitHub, there is a new simplification algorithm that uses the size of the subplots (and resolution and so on) to simplify your traces. That should be more reliable than the version here and might work better using a single figure-wide setting.


Ingrid (view profile)

I am running out of memory so I need to apply the cleanfigure. However, the scale of my different subplots is not the same so I need to apply different precisions to each subplot instead of one and the same value to all subplots - how can I achieve this???

@Ingrid: Those changes haven't been propagated to the version you can download here. If you want to try out those new features, please download instead.

@hannes fischer: The number formatting can be set using the 'pgf/number format' options in your LaTeX document. More information can be found in the TikZ manual ( ), but also the pgfplotstable manual ( ) contains a lot of information.

Hello everyone,

thank you for this tool. This helps me a lot and the plots look very good. But I'm looking for a solution of my problem for hours unsuccessfully.

Here it is:
I only want to sererate thousands without anything, I don't want a number like this: 2,000. I only want it this way: 2000.
In which line of the script do I change it?

Thank you!

@Raph: Thank you reporting the bug concerning markerEdgeColor! We will fix that.
The scatterplots with both changing sizes and colors, unfortunately, is something that is currently not supported. The thing is, both get set using the same mechanism in pgfplots (i.e. meta data), so specifying one will conflict with the other. I think there might be a way around that, but it might take quite some time to implement that.


Raph (view profile)

When the colors of the scatters are set by a colormap, the scaling of the scatter markers is also not working. When all scatters are having the same color it works fine.


Raph (view profile)

Great tool, thanks a lot.

Using scatter() I get the error

> Undefined function or variable 'markerEdgeColor'.
> Error in matlab2tikz>getScatterOptsColormap (line 3237)
> [m2t, ecolor] = getColor(m2t, h, markerEdgeColor,'patch');

Adding the line
> markerEdgeColor = get(h, 'MarkerEdgeColor');
helps, maybe you can include this or provide a better fix.


@Cornelius Thies: Datetime values on the x-axis has been added to our development release for MATLAB 2014b and newer. You can get this version by downloading the "develop" branch on GitHub (and otherwise, it will be release here as well, but I can't promise any date yet).

This tool is so helpful for creating nice plots in Latex files - thank you!
However, I have encountered one problem: I have a plot with datetime-values as the x-axis. When exporting the plot to a tikz file, only numeric values are shown instead of correct dates. Can this problem be solved?

@Andries: We do support contourf plots :-) (do make sure you have version 1.0.0 or newer). Many of those plots should work without a problem, but I have to admit there are some parts that are not yet implemented, see But those will surely be tackled in a future version.


Great file, but please support contourf plots!

Tina Fuhrmann

Thanks Egon!

@Tina Fohrmann: that is just a warning because matlab2tikz cannot determine what the phyiscal size of the figure is in physical units. You can turn this warning off using "warning off MATLAB2TIKZ:UnknownPhysicalUnit". But probably the best solution is to reset the units back to a physical one: "set(figureHandle, 'Units', 'inch')" (or any other MATLAB unit you prefer) after you have executed the code you provided. Then MATLAB takes care of the conversion.

Tina Fuhrmann

Thanks for the great file!
I get the following error
Warning: Can not convert unit 'normalized'. Using conversion factor 1.

when resizing a figure:
set(figureHandle,'Position',[0 0 0.6 0.75]);

Is there something I can do?


Jeremy (view profile)

@Sebastian Bomberg: I have added this feature request on our GitHub tracker.

@Selwyn: We do have some support for 3D histograms, but it is quite limited. In the link that you mention, Nico shows an example of 3D histograms as well. However, as you can see on, it's currently very hard to fully support such figures due to multiple reasons.

Eneko Unamuno

Thank you Nico for this great contribution!

I'm facing a little issue regarding iso contours though.
Apparently, the line spec of couture lines is ignored.

%start code

Z = peaks();


hPC = pcolor(Z);

hPC.FaceColor = 'interp';
hPC.EdgeColor = 'interp';
hPC.LineStyle = 'none';

hold all;

contour(Z, '-k', 'ShowText', 'on');

hold off;


contour(Z, '-k', 'ShowText', 'on');


%end code

counter lines should appear black but get drawn with the same colormap as the patches from pcolor. Thus you can't see them. It becomes more clear in the 2nd subplot.

I'd really appreciate your help.

@E. Ch3yn3t: you may want to try the `cleanfigure` function that is provided to clean up your data. If that doesn't clean many NaNs, feel free to submit a feature request on github at

E. Cheynet

E. Cheynet

Excellent initiative !
A given plot may contain many NaN values.
I wonder if it is possible to implement inside this script a method to automatically remove the NaN values from the created tikz file. The goal would be to reduce the size of the created file, and to increase its readability.

E. Cheynet

@PatronBernard: that's very possible, yes. We will communicate this dependency more clearly in the upcoming release.


Addendum: possibly when the title of the figure contains LaTeX markup.


Brilliant piece of software. However, is it possible that your minimal working example requires the inclusion of the amsmath-package?

Hi Ragheb,

To increase memory when using large PGF or TIKZ figures, for MikTEx use the command line:

initexmf --edit-config-file=latex

opens an editor where you can put the new values. E.g.


Afterwards call the next for updating the latex format files.
initexmf --dump=latex

FOr PDFlatex, replace in both cases latex with pdflatex


Ragheb (view profile)

Why Latex doesn't compile large tikz files?

I have tried matlab2tikz on a three dimensional sphere figure from matlab and it works perfectly because the corresponding tikz file is only 50KB. However, the figures I want to include in the tex file often exceed 100MB! Latex refuses to compile such files giving me the error :" TeX capacity exceeded, sorry [main memory size=5000000]".

Can you please advise me how to solve that problem?

Peter Pablo

@Pepijn, I reported your issue as well:

Peter Pablo

@Konrad Stahl,
this is already reported and will be improved. See

Konrad Stahl

In the new version it always adds:

every outer x axis line/.append style={white!15!black},
every x tick label/.append style={font=\color{white!15!black}}

to the TeX-Code (and also for the y-axis), even if I use

ax = gca;
ax.XColor = 'black';
ax.YColor = 'black';
ax.ZColor = 'black';

in the Matlab-Code.

Is there a way to change this? I dont't want grey axes and I dont't want to change that manually every time.

@arnold: I asked Nico to put that link at the top to reduce the amount of bug reports here and get more feedback on Github instead.

As you can see from the history of updates, we only rarely have a new release (the last one was in April) and we are very conscious about publishing them (I agree with you that such lists should not be polluted, and we try not to).

The last update here was around the time when we released the 0.5 version as well. But since FileExchange now integrates with our master branch on Github, it has become less clear what an update is: there is no manual process involved where Nico updates this page. Together with The Mathworks, we are currently looking into what a good way is to combine both GitHub and the FileExchange and provide new releases in a clearer way. Anyhow: whie this page hasn't been altered in a significant way, the code has :-)


arnold (view profile)

Hi Nico,
very useful tool and thanks very much for that.

A rather unusual remark/question: I'm confused by all the 'updates' you've been undertaking. I try to keep the files I use updates hence I check this website regularly. You have 'updated' the contribution several times under the pretense of 'present the contribution link more prominently'. I suppose you don't just do this to bump this file up the 'most recent' list but I can never find an update.

I guess I'm not the only one spending time to check for whatever it is you updated in the code. As good as the code is, the 'recently updated' list on the file exchange becomes rather useless if everybody did that, or are you trying to move everybody over to github :)


Markus (view profile)

most useful script I use, great work :)

@Vegar: m2t uses the plot units set in your figure, and those are inches by default. You can either change those or manually supply them with the options `width` and `height` (there you can also use `\textwidth`, `\columnwidth` etc.).

@Todd: font sizes are respected if you supply the `strictFontSize` option.

@Jan: `contour` is translated to a pgfplots `contour` since m2t v0.5 on MATLAB 2014b or higher. (`contourf`, however, isn't supported yet in that case).

Peter Pablo

Vegar Ottesen

The submission is EXCELLENT! However, by default it defines a plot width and height in inches, conforming to US paper standards, as opposed to ISO A4, which is more common globally.

Might I suggest a change in plot width to a fraction of \textwidth instead?

Great! needs a few more options though.

1. Specify font size of axes, legend, etc.

2. When there are multiple axes in a given Matlab figure, the axes are not spaced properly in latex.

3. Option to include extra code inside the tikzpicture environment.

I use this all the time!

nice job

Jan Kappen

Extremely good.

But two little questions:
First one: Are contour plots supported? I mean the pgfplot's contour. If I use 'contour(peaks(20),10);' and export it with m2t only area plots are used.

Second one: If I use 'contourf', the ticks are invisible, tick labels are there. Is that a bug?

Thank you!


Sharah (view profile)

I hope anyone can answer this. This words fine if i plot a figure and then just change it to tikz.

But a problem comes when I try to add some personalised text on the figure, and when i try to include it in tex file, it says error something like

Package pgfplots Error: the arguments of [mesh/rows=2,mesh/cols=0] assume 0 p
oints, but I got actually N = 1 points! The data matrix appears to be incomplete

Georg (view profile)

I have a custom positioned colorbar, the script doesn't account for that yet. Might that be something you're looking into in the future?


Simone (view profile)

For the version 2014b it has problems. For instance the legend disappears.


Nico (view profile)

Thanks for this excellent script!

I experienced two issues, which I tried to solve with some hacking of the code (use with caution :)
(I am running R2013a and pdflatex)

1) multi-line legend entries:
Minimal working example: in matlab, run:
figure; plot(1:10, 1:10); legend(sprintf('This is a \n multiline legend entry'))
matlab2tikz('filename', 'm2ttest.tex', 'width', '0.8\columnwidth', 'height', '5cm')
In latex:
\pgfplotsset{plot coordinates/math parser=false}
---after \begin{document}---
\caption{TIKZ Test}

Result: the legend entry appears in one line. There is a line break in m2ttest.tex which latex ignores.
My attempt to fix this:
a) change in function prettyPrint, line 4840 (see diff at bottom)
b) change in line 731 (see diff at bottom): add "[align=left]" to "\addlegendentry". Without this, my latex aborts with an error if a line break "\\" is used in the legend entry. I have seen that matlab2tikz sets the legend style to "legend cell align=left". Why the additional, explicit specification "align=left" is necessary is strange... maybe I am doing something wrong?

2) Positioning of the legend:
when I move the legend to, say, the bottom left of the figure (in the gui), it does not appear (exactly) at this position in latex. The problem seems to be that in matlab, the legend position is relative to the figure, while in tikzpicture, it is relative to the axis. Starting at line 3646, matlab2tikz seems to try to determine whether the matlab position is relative to figure or axis (unit = "normalized" or "pixel"). In my case, the unit is "normalized", but the position is still relative to the figure. So I just modified the script to always act as if the unit was "pixels" (copied the code from the "case 'pixels'" to the "case 'normalized'"). After that, legend positionig worked as expected.

What I modified in matlab2tikz.m:
diff matlab2tikz.m.orig matlab2tikz.m
< sprintf('\\addlegendentry{%s};\n\n', join(m2t, c, '\\'))]; %#ok
> sprintf('\\addlegendentry[align=left]{%s};\n\n', join(m2t, c, '\\'))]; %#ok
< position = legendPos(1:2);
> %position = legendPos(1:2);
> % Calculate where the legend is located w.r.t. the axes.
> axesPos = get(m2t.currentHandles.gca, 'Position');
> % By default, the axes position is given w.r.t. to the figure,
> % and so is the legend.
> position = (legendPos(1:2)-axesPos(1:2)) ./ axesPos(3:4);
> %now that all the character arrays in strings are 1-dimensional, we additionally need to split strings at newline characters
> strings = cellfun(@(x)strsplit(x, sprintf('\n')), strings, 'UniformOutput', false);
> strings = [strings{:}];

Add these lines at the end of your script before running. It did work for me

Really nice tool. I just tried to convert a figure which uses scatter(X,Y,[],C) to draw circles with different colors.

There seems to be a bug in your code (or the feature is just not implemented yet) in the getColor(m2t, handle, color, mode) function. It doesn't seem to be able to handle multiple colors.

A simple example would be this:
scatter([1 2], [1 2], [], [0 0 0; 0 1 0]);

Which results in an error. Do you think you can fix this? Would be absolutely great ;)


Kine (view profile)

Love the way te figures look! But I have one question, is there any way I can force the limits for the axis ? For example I am making a figure that has the values 0.005, 0.006... on the x-axis, and when I put the figure in to Latex I get 0.5 * 10^{-2}, is there anyway I can force it to be as it originally was? And Is there anyway to force the y-limits to be spesific values?


Jan (view profile)

Instant five stars for you because not only is it quite powerful, as noted, but also extremely easy to use. Thank you!

Fabian Abarca

An essential tool from now onward when working in Matlab/LaTeX. There is, though, some trouble in the legends of the plots when TeX symbols or code is introduced (say P_e) and the tikz file takes it as plain text, but I guess it can be fixed (I do it manually in the generated file). Excellent file, thanks.

Aaron Jackson

A very useful little tool to have in your MATLAB path. :)


first of all, really nice tool! it produces the most beautiful plots in combination with TeX by far!

Just a little question, in order to match german typography I replace all the point seperators by comma seperators -before- using matlab2tikz.
That works pretty well for axis labels, the title and the tick labels. But there seems to be a problem concerning the legend entries:

Some of my legendentries contain numbers which are seperated by points since they are created dynamically using num2str(). They are written in combination with some descriptive text. So one legendentry could be:

$\lambda = 1.5$, $Delta = 3.4$

after replacing the points by commas it could be
$\lambda = 1,5$, $Delta = 3,4$
$\lambda = 1{,}5$, $Delta = 3{,}4$ (I tried both types).

After using matlab2tikz on the figure, the "original" comma in the legendentry is kept, while the seperator commas are replaced by point seperators again...

I hope you understand what I mean and maybe you've also got some hints on solving that problem

Hey there,

I updated today to version 0.4.5 and there are several .tsv-files created instead of one large .tikz-file.

that may be advantageous for many of you, but I'd rather have one large .tikz-file.

Is there any way to change it back?


Tina (view profile)

I figured out the problem:
The texlive version for Ubuntu still uses pgfplots 1.8 but for the newest matlab2tikz file pgfplots 1.9 is necessary (for plots with errorbars).
It's somewhat a pain to install pgfplots 1.9 in ubuntu but after doing so it works fine again.

Maybe with the next update there could be a hint that another pgfplots version is needed.


Tina (view profile)

Hey there,
I just love matlab2tikz, thanks for the file!

Unfortunately I have a problem with the errorbars now:
In the older version v0.4.2 points and bars were defined as (x,y)+-(xerr,yerr)... .
Now in version v0.4.4 it is (x,y) += (xerrup,yerrup) -= (xerrdown,yerrdown). It doesn't work for me to compile that file in texmaker. Did anybody have the same problem and/ or knows how to solve this?

Thank's for your help.

I think there is a problem when exporting bar plots while using the 'figurewidth' variable to enable setting the figure size in Latex. The width of the bars are set to the same value as 'figurewidth'. This makes the bars way to wide.

@Anfänger Sounds like a bug. If you want it fixed, file a report at <> with a minimal MATLAB example that highlights the misbehavior.


Just a small correction for my question: by labels, I mean , when I put contour labels withing box, the box is ignored by matlab2tikz. If for example I swich axis position (x-axis in the top), the label is still written at the bottom by matlab2tikz


@Nico Schömer , many thanks for the great job. If you allow me, I would like to ask Why is the m2t ignoring for example labels, added texts...etc?

Nico Schlömer

1. There is the option 'extraAxisOptions'. If that doesn't work for you, you could file a bug at <>.

2. There's cleanfigure() to help you out.

3. That's possible, you're probably the first to use step/impulse plots with m2t. It'd be great if you could file a bug and provide minimal failing examples.


How do I use the cleanfigure() function? I need to reduce the number of datapoints in my plot. I run cleanfigure() but nothing changes. Can someone help me?

Thomas Bosse

So cool! Thank you!


Pretty amazing submission. I have only had a few minor issues with it:

1. There is no way to provide extra axis options (e.g height and width) for each subplot. This is especially needed when you have a few vertically stacked subplots with a common x-axis and you want to remove the x-axis labels from all subplots but the bottom one, or you want different heights from each subplot.

2. It needs a better (smarter) downsampling algorithm. Currently, it is very easy to hit TeX memory limits when you have a large number of points (see

3. It cannot properly convert time graphs that are automatically generated by step(), impulse() functions and the like (from control system toolbox)

This is very cool thing, the result looks really great than png images.


Excellent!It did in fact save a lot of time and work. I am new to tikz, and would like to ask, is there a way to generate both the .*tikz and *.pdf files? without the need to open the .*tikz file in an external editor and generate the pdf version.

José Goulart

Very practical, and the result looks really great.

Svenja Woicke

is it possible to change the code such that the "point meta min" and "point meta max" values are always saved so in case i choose for adding a colorbar later on it will show the right scale?

The whitespace issues (cf Christoph, March 25, 2013) have not entirely been fixed, though (v.0.4.0):

Around the "definecolor" lines, some more '%' should be placed:

m2t.content.colors = sprintf('%%\n%% defining custom colors\n');

line 562, too:

m2t.content.colors = [m2t.content.colors sprintf('%%\n')];

Thanks for adding this in future updates! Great work!

Awesome package, but I have a problem with the 'floatFormat' parameter.
If I don't set this parameter all data points get written in the resulting *.tex file - but then it is to big.
So I set the precision like that:
matlab2tikz('myfile.tex', 'floatFormat', '3' );

In the output no data points will get written, only '3's in this example.

Is this a problem or do a use this parameter in a wrong way? Thank you!
I hope you can help me.


Very great package, thanks a lot! But I have a small problem I can't fix. I need to add "mark repeat=25" as an extra parameter in the "\addplot" option list. But I cannot figure out how to do it. 'extraTikzpictureSettings' puts it before the \addplot environment. Is there a change to add an input variable fixing this problem? Thanks again!


first of all: Very Good Tutorial! Thanks for it.
I have a problem with the tikz-file and i don’t know how to fix it.
The label of my y-axis overlapes with the scale on the y-axis. The reason is that the values ​​of the scale are very small and are multiplied by 10^-3. Instead of 10^-3 is on the top (as in the x-axis), all values of the scale are multiplied with it seperately, e.g.
1 * 10^-3
8 * 10^-4
6 * 10^-4

and so the label overlapes with the first column of values. I don’t understand why is in the right form in the x-axis but not in the y-axis. In my Matlab-figure there is everything ok.
I hope i explained it understandably and somebody has a solution for this problem.

Matlab2Tikz is a great tool! Thanks a lot for sharing!
@ Nico: You did a fantastic work which helps me a lot. However, there is a minor thing you might want to change in a future release (currently unsing 0.3.2): If one is trying to convert a contour(f) plot and include the result in a tex file, one gets in trouble with the alignment. This is caused by the preamble of the resulting file, with some blank lines and the \definecolor command. In my latex distribution (miktex) every linebreak causes a small shift to the right (propably a 'blank' is interpreted) and as more colors are defined as further the figure is shifted. To avoid this behavior I added %% where the \defincolor is set up, and thus it reads: sprintf('\\definecolor{%s}{rgb}{%.15g,%.15g,%.15g}%%\n'
 To get a really tight boundary box, some other lines in the preamble might need %-sign, too.
If you want me to, I can send you a simple example showing the problem.

Best regards,

Georg (view profile)

Works fantastic - I have just one little suggestion: Could you convert the RGB values of the plots to CMYK when defining the custom colors? This has proven to be necessary for correct color disply in the Adobe Reader when using pdflatex and seems to be a widely known problem

Nico Schlömer

Nico Schlömer (view profile)

@Karthick You can use the resulting file with `latex` (generating a PS-document) as well as `pdflatex`, fonts come out just as they are in the LaTeX document, you can customize your plot after it's been generated, and probably a bunch of other reasons. All in all, when you compare MATLAB's generated PDF with the compiled output of matlab2tikz, you'll notice a distinct difference in quality.


its indeed a good package. But what advantage it has from "print as pdf" option in matlab?

Dear Niko

I am trying to convert a 3d plot with many patches, but the ordering is incorrect. Some patches that should appear behind others, appear in front. I am not sure if this is a tikz problem, but was wondering if you have encountered this as well. Any help would be appreciated.

@Anke This is currently not possible with m2t alone, and I wouldn't even recommend it for line plots -- after all, m2t cannot tell which data is important for you and which can be stripped.

Dear Nico,

is there a way to manipulate the order of the plot elements? It doesn't seem respect it as soon as I plot data points and lines, e.g. plot(x,data,'k.',x,fit,'r-') plots the black points in the foreground, regardless of Matlab's plot order, rendering the red line practically invisible for large datasets. The same problem occurs with 'ko', while 'k-', i.e. lines for both elements, works like charm and places them in the correct order.

Thanks in advance

\text is defined in the amsmath package. Try to include '\usepackage{amsmath}' in the preamble, this should solve your problems.

% Construct the interpolant

% F = TriScatteredInterp(x,y,z,'natural');
F = TriScatteredInterp(x,y,z,'linear');

% Evaluate the interpolant at the locations (qx, qy), qz
% is the corresponding value at these locations.
ti = -2:.25:2;
[qx,qy] = meshgrid(ti,ti);
qz = F(qx,qy);

hold on
view(gca,[-69 14]);
hold off

matlab2tikz( 'testplot3D.tikz', 'height', '\plothoehe', 'width', '\plotbreite', 'parseStrings', false);

Three things:

2.: I set the width an the hight via "\pgfplotset{}" in my preamble and just change it for a few plots. Matlab2tikz always outputs width and heigh parameters which in this case isn't very usefull.
(just found the Wiki which provides a good work around for that - "\newlength and \setlength")

Hi Sebastien,

the #-issue should be fixed now; thanks for the report.

Sounds great in a first try.

One thing, if my xlabel is xlabel('# K') in matlab, the produced file is buggy (manually changed xlabel={# K} to xlabel={\# K}) in the tikz file).

How to keep the aspect ratio for legend ?

very nice script!! I've been using MATLAB EPS export and then editing with Inkscape and saving as PDF+LaTex solution so far, but this one is simpler and better as it solves in an elegant way the label positioning problems of my former solution!

Hi Nico,
Thanks again for the great work.

Few requests:
1. Is it possible to have a command line switch to put all Matlab legend entries just in {}, instead of $$ + \text{}? My legends are mostly non-formula, so I can format them much easier if they come through matlab2tikz in this shape.

2. I propose to put "defining custom colors" section before \begin{tikzpicture} because if you make legends in the fig. caption (by using \label{} and \ref{}), LaTeX will report an error without this, since \definecolor is only scoped to tikzpicture.

3. Related to 2: Any chance of automatic labeling of plots? For example \label{filename-p1}, \label{filename-p2},....


Hi Nico,
it might be better to use filename an path of uiputfile (line 206, 212, 218, ...), so files can be stored elsewhere than the current folder.

Thank you.

I have emailed you my modification to the nested function drawText in order to deal with problems in text objects created using Matlab TEXT command. If you agree with that, you could update your code accordingly and save me from modifying everytime there is a new version. Thanks.

@Alexander Klein: I implemented one or two things, you may wanna check out the latest release.
For future changes, it's best to submit a bug report at

Well, the documentation may not be up-to-date all the time.
In general it's always worthwhile to take a peek at
All the options are also listed in the source file itself of course, so you can always look at lines 125 ff. Should be pretty self-explainatory.

1) Not sure I understand what you mean.
2) You mean the image width? There are 'width' and 'height' arguments.
3) Option 'mathmode'.

Generally, if you found a bug or similar, it's easier for me to follow it up on GitHub.

Thank you, Nico, the script is a work of art. I am an experienced LaTeX user (what I used to write my dissertation), and very comfortable in MatLab (minus any major plot generation). Thus, when I found your code, you can imagine how thrilled I was as I am building scripts for report generation at this time. This would be, easily, the best script I have ever encountered on this file exchange if I could find how to:
1) Remove the 10^5 in the x-axis label (I also use datetick and have added the suggestion by Mukhtar to the LaTeX preamble to no avail).
2) Predefine line width, image aspect ratio, and some sort of a scaling parameter, so that the output width and height parameters in the tikz, e.g.,


3) Some sort of understanding of how I can specify whether or not the title, axis labels, legends not be interpreted in LaTeX math mode (or do you suggest that I hard code this)?

Perhaps such features are supported (as mentioned by Petter), however a quick browse through the m file didn't give me much of a starting point.

@Alexander Klein, I am interested to know if your improvements were ever implemented by the author?

Thanks all for everything,

Matt Bauman

It was because matlab2tikz wrapped my x and ylabels with $..$. I removed that piece of code and got my expected results.

@Petter: You have an example-code for which the spaces in xlabel doesn't work? In all my figures it works perfectly, so I assume it's something with your code.

Otherwise you don't use \includegraphics with TikZ figures (unless you pre-compile to PDF or something), but using the width/height commands already available will set the dimensions of the figure (these commands are also documented in the description here on FEX).

Spaces in xlabel doesn't seem to work


Petter (view profile)

Seems it was already supported, but not documented.


Petter (view profile)

Looks good, but I am missing the functionality to keep the aspect ratio and change the width. E.g., \includegraphics[width=3cm]{image}

The help does not cover the optional arguments.

Hi everybody!

first of all: Thank you Mr. Schlömer for matlab2tikz. This is a great piece of a software.

Unfortunately, I have had the following problems when using version 0.0.7 in Matlab 2009b on a 64bit Linux system:
1. Labels and titles could not be written by sprintf, since it where cells.
2. Barplots did not work, since there was a typo (e.g. m2t was missing)
3. I need to plot time signals with a very small difference. That is why the precision in the pgfplots coordinates were not sufficient.
4. When plotting data series with several thousand data points, it took minutes to write the file (due to strcat and a lopp for i=1:length(xData)

I have made changes to the file which takes care of this issues:
1. e.g:

  if iscell(title)
      title = title{:};

2. for me replacing
barplotTotalNumber = barplotTotalNumber + 1;
m2t.barplotTotalNumber = m2t.barplotTotalNumber + 1;
3. I added an option for the script where you can add a precision of the format string that is used when writing to the pgf file
4. I replaced the for loop with a repmat construction that reduced computation time a lot.

If anybody has encounters the same issues, I can send this file to Mr. Schlömer maybe (if he likes to add the changes). Or is there a better way to take care of that?

Kind regards

Works great!

Wondeful tool. Today, I tried it and it could be no better than that. I faced that same problem ( that annoying x10^5), as mentioned by Paul, but that has nothing to do with malab2tikz.m but the way pgfplot processes the tick labels. I found a solution, though, which I would like to share and request Nico to include it in the readme file.
Add this to your latex document preamble
\pgfplotsset{x tick label style={/pgf/number format/fixed}}
\pgfplotsset{y tick label style={/pgf/number format/fixed}}
Of course, you do not need that if you are happy with the x10^5 notation.

Hi everybody ! My name Ngo Huy . i am studient four year of Ho Chi Minh University of industry . I have a project graduated processor image (Product Classification in (closed chain stoppers)

Amazing tool !!! Thank you very much.

I have an annoying problem though. I have coordinates imported from as matlab serial dates, which I then re-label using xtick. Works fine except when pgf plots the graph there is an annoying x10^5 in the bottom right corner (which must originate from the matlab serial date values.)

i.e., the code I have is :


scale only axis,
xmin=724642, xmax=733408,
ymin=0, ymax=3.5,

Could somebody please help me with this?

Best regards

Excellent Tool, plots come out looking great!

A really useful package. I hope it will support every plot types soon (particularly the scatter type ;-))!

I've used this submission extensively to add plots to my LaTeX-Files and it works like intended. Thanks for that submission!

This would be much better if you explained that one needs to upload pgf and pgfplots latex packages and call \usepackage{pgfplots} in the preamble of your LaTeX document. After that it seems to work alright.
