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)

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.

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

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
