Subplot tends to leave a lot of empty space around the axes. Tight_subplot allows to adjust the spacing between the axes as well as the margins around the axes.
For example:
[ha, pos] = tight_subplot(3,2,[.01 .03],[.1 .01],[.01 .01])
for ii = 1:6; axes(ha(ii)); plot(randn(10,ii)); end
set(ha(1:4),'XTickLabel',''); set(ha,'YTickLabel','')

This is an excellent function!! Thank you so much for your post!! :-)

@Megan Fowler
You might use a combination of set and get. This worked fine for me.
originalSize = get(gca, 'Position');
cb = colorbar;
set(gca, 'Position', originalSize);

Thanks!

This is very helpful! One issue I'm unclear on is how to add a colorbar to one subplot without screwing up the alignment with all the other panels in the figure - is there a fix for this?

Jonas Stein

thank you. PS: The ';' behind the three if-lines are unnecessary.

if numel(gap)==1;

Really useful, thank you!

非常感谢作者提供的函数命令,非常有用!(thank you so much for your this code,it is very helpful to me!)

This really made my dissertation work come together nicely. I've used it hundreds of times, and appreciate it hugely! One question now that I'm using the function to generate some different plots: is it possible to specify that the bottom of two subplots take up less of the figure area than the top? I.e. the top plot would have, say 500 pixels in height, and the bottom 200? Cheers.

Nice but I had to add a shift parameter to stop my tick labels on the left from being truncated (as per below where the "bias" parameter is a new 2 element vector input arg and just added to the position as follows

'Position',[px+bias(2) py+bias(1) axw axh], ...

I guess it would be nice to have it totally auto centered (not that I know how off the top of my head) but I'm just really happy that you wrote this. Thanks.

This function does not follow subplot's default syntax because this is not subplot but another function. The third input argument is the gap between axes. Not the number-in-order of the axis to set as 'CurrentAxes' of figure as in subplot. See help for description of the input arguments.
There seemed to be an ancient version in Fex, I updated a mre recent version, which makes it easer top live with colorbar and other functions, which modify the positions of existing axes.

A discussion about the problems in the subplot here http://stackoverflow.com/q/35770961/54964 where colorbars with an example and subplot's 3rd parameter are discussed.

Does not follow subplot's default syntax by omitting the third parameter. Fails with colorbars.

Undefined function or variable 'tightfig'.
Why i encountered this problem and how can i do?

Natan

this is one of the most useful FEX contributions I have ever encountered. Thank you for the effort!

Ashley Zhang

Excellent function!
Yet I have one problem. When I plot odd number of subplot, say 7 plot arrayed as 4*2, there is always one blank plot that I cannot remove even though I delete the last value in ha.
Any one have any idea to fix it?

* Problem fixed by setting axis, XColor and YColorthe of the last plot invisible.

subplot(ha(8)); set(gca,'Color','none','XColor','none','YColor','none');

Excellent function. Works fine for me.

Excellent function, thanks. The one thing I am missing: Is there a way to connect different subplots, as in subplot(4,2,[1,3,5])?

this file really helped me! however i have one question. i want to set fixed limits of the x,y axis in each subplot.For example: (axis([0 700 -500 10000])).i tried to do it but with no result. any advice of how can i do this?

It's great that it offers variable outer margins in addition to inner gaps. I wish it could support asymmetric plots, where a panel spans multiple rows/columns, though.

Nice, very handy, though by default I prefer my tick labels left on... others who want this might just mod the file.. just remove in the inner loop where it sets the ticks off... i.e.

for ix = 1:Nw
ii = ii+1;
ha(ii) = axes('Units','normalized', ...
'Position',[px py axw axh]);
px = px+axw+gap(2);
end

useful and does what it claims

This is a great script. I'm experiencing a bug that makes my ticks disappear. Here's a sample:

figure('position',[100 100 1000 600])
ha=tight_subplot(1,3,[.02,.02],[.12,.08],[.1,.02]);
for a=ha'
hold(a,'all')
box(a,'on')
xlim(a,[.1 10])
ylim(a,[-90 10])
end
set(ha,'xscale','log','fontsize',fontSize,'ytick',-100:10:20,'yticklabel',[],'yminortick','on')
set(ha(1),'yticklabel',-100:10:20)
% 1
scatter(ha(1),x11,10*log10(y11),30,[0 .5 0],'x');
scatter(ha(1),x12,10*log10(y12),30,[0 0 1],'filled');
% 2
scatter(ha(2),x21,10*log10(y21),30,[0 .5 0],'x');
scatter(ha(2),x22,10*log10(y22),30,[0 0 1],'filled');
% 3
scatter(ha(3),x31,10*log10(y31),30,[0 .5 0],'x');
scatter(ha(3),x32,10*log10(y32),30,[0 0 1],'filled');

I would expect to see xticks at .1, 1 and 10, but on my system they simply disappear. If I tried and add them manually the log scale gets screwed up, so there's gotta be another way around. I'm using Matlab R2012a.
Thanks!

Really excellent file, thank you. Maybe an extra example wouldn't be a bad idea in the comments for the new Matlab user to better learn to use this file.

I have two questions though if I may ask them here...

1. How do i add numbers on the y axis? (only on the rightmost side of course)

2. How do I write x & y labels? (only one that applies to all axis)

Thank you in advance.

Very nice, needed something exactly like this, and it's quite easy to use.

i cannot do anything but give a five star! absolutely smarter than mathworks!

Hey,

Great function. Pity I came across it after I spent much of my time writing a similar function. As some people have said above, I wanted the function to work with multiple rows/columns spanning subplots. So I included that capability in the following function:

http://www.mathworks.com/matlabcentral/fileexchange/35464-spaceplots

Just thought it might be useful to some.

I second what Dan said. Spanning multiple columns/rows would be really useful. For example:
ha = tight_subplot(2,2,0.1,0.1,0.1)
axes(ha(1));plot(x1,y1);
axes(ha(2));plot(x2,y2);
axes(ha([3 4]))plot(x3,y3);

Thanks a lot for the script.

Great work. Would be nice to be able to have the subplots fill a uipanel instead of the entire figure (doesn't play with within a GUI).

Nice function, and one that I've come to rely on. It would be great if axes could span multiple columns/rows as you can do using the built-in subplot. Otherwise, great.

Oops -- didn't know that rating the submission meant submitting. Excellent function that saved me tons of time in having to generate graphics through GIS. No clue why the subplot command has this issue, but thanks for addressing it!

Excellent little script! Thanks a lot!

Still, I have one suggestion: Instead of saying "axes(ha(ii));" in the example a better way may be to say "subplot(ha(ii));". Using axes gave me unpredictable behaviour when setting up two plots side by side. I would (almost always) plot to the axes on the right, no mater how often I tried giving the "axes(ha(1))" command (or "axes(ha(2))" for that matter). Using subplot solved that. Don't know why though ...

Good work. I needed to create several plots with several sub-plots within a loop. Had trouble with empty plots as the result and Matlab was broke until I restarted it. Even a plot(1:100, rand(1, 100)) would return an empty figure. Anyway, I returned the value for the axes position matrix "ha", and removed the internal axes command. When I was ready to plot in one of the figures I had being created to a specific subplot location I called:

figure(h4);
subplot('Position', ha4(fc4).pos); p=plot(1:100, rand(1, 100));

where ha4(fc4).pos corresponds to the fc4'th subplot position in figure with handle "h4".

Alexander

Thank you for this contribution. I like it very much.
In my opinion the input check should be like that:
if nargin<3 || isempty(gap); gap = .02; end
if nargin<4 || isempty(marg_h); marg_h = .05; end
if nargin<5 || isempty(marg_w); marg_w = .05; end

So you can modify marg_w and take the defaults for the other parameters.
tight_subplot(nrows,ncolumns,[],[],[.1 .05]);

i dont know what mathworks was thinking with their subplot routine... this is much nicer

Positions of the created axes objects are returned. Allowing to reset the positions after some standard functions, which reposition existing axxes (eg. colorbar)
