Editor's Note: This file was selected as MATLAB Central Pick of the Week

Alters a figure so that it has the minimum size necessary to
enclose all axes in the figure without excess space around them.

Works for figures containing multiple axes as subplots.

Note that tightfig will expand the figure to completely encompass all
axes if necessary.

Returns an error if the figure contains any 3D axes which have been zoomed.

Thank you! Works as advertised for plots and fcontours, even with multiple subs.

Great tool.

Any idea why it has trouble with figures that contain annotation text boxes? My workaround is to run 'tightfig' before I invoke the 'annotation' command.

Isaac Li

Awesome function for all cartesian plots.
However, it doesn't work with polarplot function. when polarplot is presented they get squeezed as if they don't exist.

Ray Lee

It would be nice to also reduce the margins among subplots.

Update posted by Jacob D is unfortunately insufficient for colorbars with labels and tick labels, as resizing doesn't consider their size and can crop them.

Colorbars don't have an OuterPosition property (Matlab 2016a). Their Label is a Text object, so its Extent property can be used to calculate its Position, so that can be adjusted for. However, I don't know any way to get the tick labels' extent (and that of the multiplier, shown above them, such as x10^-4), so those might end up being cropped. Any ideas how to get to them?

In R2015b, I had to change Jacob D's edit as follows:

    ti = [get(hax_ti,'TightInset'); ...
        zeros(size(pos)-[sum([hax_ti_ind{:}]) 0])];

But otherwise it works now with legends so thanks!

In the code I posted previously, the following line can be commented or left out:
% hax = sort(hax,'descend');

Axes should already be first after the concatenation.

To fix the issue where tightfig doesn't adjust for legends and colorbars in HG2 just use the following three sections of code in replacement of the current tightfig code:

%% Section 1 replacement
% get all the axes handles note this will also fetch legends and
% colorbars as well
hax = findall(hfig, 'type', 'axes');
% Concatenate HG2 objects into hax as graphics array and sort
hax = [hax; findall(hfig, 'type', 'legend')];
hax = [hax; findall(hfig, 'type', 'colorbar')];
hax = sort(hax,'descend'); % Make sure Axes are first in the list

%% Section 2 replacement
% get various position parameters of the axes
hax_ti_ind = arrayfun(@(x) (isa(x,'matlab.graphics.axis.Axes')),...
    hax,'UniformOutput',false);
hax_ti=hax([hax_ti_ind{:}]); % Returns only Axes handles
if numel(hax) > 1
% fsize = cell2mat(get(hax, 'FontSize'));
    pos = cell2mat(get(hax, 'Position'));
    ti = [cell2mat(get(hax_ti,'TightInset')); ...
          zeros(size(pos)-[sum([hax_ti_ind{:}]) 0])];
else
% fsize = get(hax, 'FontSize');
    pos = get(hax, 'Position');
    ti = get(hax_ti,'TightInset');
end

%% Section 3 replacement
for i = 1:numel(hax_ti)
    set(hax(i), 'LooseInset', ti(i,:));

Doesn't work for 'boxplot'.

I was looking for the easiest way to remove extra margins on my figure, can't really get any easier than writing tightfig(fig)

Unfortunately it cuts out colorbars when using 2015b. I'm guessing this is due to the new plotting system, where colorbars are no longer axes objects, but I don't have the expertise to fix it.

Doesn't work very well for bode plots. Axis label overlaps with ticks on x axis

@ADITHYAN, for imshow, you can use iptsetpref('ImshowBorder','tight');

ADITHYAN

Useful function!
When I use this function with imshow, there is still a white space on the left of the image.
It would be nice if you can fix this. Thanks.

Paul Quelet

Works wonderfully.

compterbs

Thank you, no problem now for trimming Latex figs

Angelo Tafuni

Now I don't have to worry about trimming in LaTeX. Great job!

I solved PDE with numerical method and I have 3 component (U,x,y) that (x,y)=[-1,1]*[-1,1]
 and U is answer PDE< How can I use this function ?
Please any tip or example send to me through email:

very helpful! Thanks for sharing.

It works fine but not when the figures are docked because it modifies the figure properties and not the axis ones. Anyway it is a great function. Hopefully it will work also when the figure are docked.

I had a colorbar addded to my figure of multiple subplots. The annoying thing was that the exponent of the colorbar was cut-off on the edge of the figure. Using tightfig fixed this for me so that the exponent would fit in the figure. Very useful!

João

João (view profile)

Great. Although it sometimes clips the edges off fonts that are really close to the limits (I was not able to understand in which conditions it does this, but it happened unfrequently)

it doesn't take into account an xlabel of a boxplot. Just cuts it away. Ylabel seems fine though.

Chad Greene

Chad Greene (view profile)

I use this frequently; thanks for sharing. I recommend adding this to the end of the function to suppress unwanted outputs:

if nargout==0; clear hfig; end
 

arnold

I'll see when I find the time to look into it.
Something else I just noticed: Using plotyy and setting both y-labels, title, xlabel etc and tightfig. to wrap things up. Tightfig seems to fast somehow. It messes up the figure window. It works if I include a pause(0.2) before tightfig. Strange..... but the workaround is no problem of course.

Richard Crozier

@arnold, I'll implement this if you suggest how to identify them. Unfortunately I don't have time to do a lot of research on this right now.

arnold

arnold (view profile)

too bad it doesn't recognize my x-labels when using hierarchicalboxplot. It would be most useful if it were looking for all elements in a figure, not just axes.

Pablo Deossa

very useful!

Perfect. Very useful if you are using the Windows clipboard to copy figures into Word and need to trim off the excess whitespace beforehand.

Richard Crozier

Hi Jurgan, from the description for crop.m I gather it crops whitespace from a bitmap (i.e. non vector type) image file which is already saved to disk, e.g. a jpeg, bitmap, png etc. It does not appear to act on figures.

I suppose you could get similar functionality to tightfig by first saving your figure to disk in one of these formats, then running crop.m on it. I prefer the tightfig workflow personally.

Jurgen

Jurgen (view profile)

I see, I have export_fig. Based on what you said then maybe CROP (http://www.mathworks.nl/matlabcentral/fileexchange/20427-crop-whitespace-from-an-image) is worth comparing :)

Richard Crozier

Jurgen, most of the functions you mention adjust the space between and around individual axes in subplots, and at least some have to be called on creation of a subplot. tightfig crops the white space around the outside of all the axes (and legends) in any figure without adjusting the rest of the plots at all. tightfig also identifies if you have a 3D zoomed axes in your figure and ignores it, since such figures cannot be cropped. tightfig is also well commented so you can understand it's workings.

Actually you failed to identify the one other function on the file exchange I know which does also have this functionality, export_fig.m.

Jurgen

How does this compare to: spaceplots, subplot1, tight_subplot, subplot_tight and subplotplus?

Ben

Hi, I found this very useful. However, I have one suggestion: in the line
ti(ti < 0) = 0.1

You should consider
ti(ti < 0.1) = 0.1
instead.

I had a graph where the top line of the outer box was being cutoff by saveas after I used tightfig, presumably because it had some ti in (0,0.1).

Richard Crozier

Thanks Thomas, I've submitted a new version with the fix.

Thomas

Thomas (view profile)

Great work... i was just going to implement it myself... but here it is ;) Thank you.

Just a minor issue:
Restoring the original axes units fails when there is only a single axes object in the figure:
            
set(hax(i), 'Units', origaxunits{i});

... since origaxunits is no cell array then. A simple if else does the trick.
