Remove excess margins from figures.

Editor's Notes:

File Information
Description

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.

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!

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.

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

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.

@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.

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.

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

22 Dec 2012 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.

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 :)

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.

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

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).

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

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.
