How can I save a plot to a variable to be printed later? I'm more specifically referring to problems of plots which involve many different legends/ figure objects such as ones created by looping over a hold on command.

I've got to do this thing for uni where I loop over a bunch of objects and plot their calculated divergences. They (32 different classes) are all calculated individually, then have a bar plot printed and then are looped over to plot the whole lot sequentially. I need to then plot a separate plot with specific axes and then am further going to do this again.

This computation can take quite a few minutes each time, so it seems so dumb that I have to run it like 5 times every time I need to change one thing, when each of these 5 plots will be plotting the exact same data.

To save plot results programmatically use “saveas() function”. Read its documentation below:

Also I came across similar question, find it's here: https://www.mathworks.com/matlabcentral/answers/68364-how-to-save-a-figure-through-each-run-of-a-for-loop

Ay cheers. Turns out I was using the figure function wrong, and the following was probably all I was looking for:

if true
  f1=figure;
  ...
  f2=figure(f1) %or f2=figure; and then some type of copy function
  ax=f2.currentaxes;
  ax.xlim etc.
end

I'll check your answer though, cheers.
