exportgraphics: adding a margin

Is it possible to add a margin to figures saved using the exportgraphics function?

It crops a tad too tightly for my needs.

Hey there, you can use 'padding' in the exportgraphics option, but it is available only in matlab online 2024a. For example:

exportgraphics(ax,"figurepadding.png","Padding","figure")

or

exportgraphics(ax,"figurepadding.png","Padding",20)

See documentation:

You can force exportgraphics to export the entire figure by drawing an white rectange around it with the command

annotation('rectangle',[0 0 1 1],'Color','w');

To adjust the margins, change the dimensions [0 0 1 1].

As noted by @David Walwark in the comments, the plot will not be interactive while it is annotated. To restore interactivity, delete the annotation after calling exportgraphics.

a = annotation('rectangle',[0 0 1 1],'Color','w');
% -> Save figure here <- 
delete(a)

Thanks @Paul Wintz, I had the same problem, this is the best solution for it.

[David Walwark]

Excellent, this really helped. If one wants the figure to remain interactive then it is best to delete the handle to that annotation after exportgraphics is called.

This didn't work for me. Presumably when doing 2 subplots you need to apply this annotation to each subplot?

I tried adjusting the margins to [-0.05 -0.05 1.05 1.05] and it raises:

Error using annotation (line 116)

Position values must be between 0 and 1.

Had the same issue... this worked for me, but I had to change the color of the annotation rectangle to something other than white for it to work.

Hi Dormant,

If you are trying to export multiple sub-images/plots onto a single figure, you can explore the tiledlayout to introduce spacing using the 'TileSpacing' Name-Value pair.

[Paul Wintz]

This doesn't answer the question. How do we adjust the margins on the outside of a figure saved with exportgraphics?

[Bill Tubbs]

This worked for me. When I did my 2-plot figure using tiledlayout instead of subplots the outer margin was significantly wider.

Many thanks to you all. I gave up on this approach as I needed to specify sizes exactly. So there's a new question here: https://www.mathworks.com/matlabcentral/answers/2158290-specify-plot-box-position-for-tiled-layout?s_tid=srchtitle
