I have a GUI which gets input from user and plots the step response. I want to export that graph only, not whole figure window. Can you help how to do?

This is the figure saved from that GUI. As you can see that it has captured the whole figure window layout, however I want to save only the plot in the figure as an image on my computer.

Can you just make a new figure window and put only the plot on that one and then export that new figure? Note that you can make the new figure invisible if you don't want the user to see it: f = figure('visible','off'); It will still be running in the background and you can programmatically export the stuff on the new figure f that only contains your plot

You are right but my problem is that I will have a different plot every time because a drop down menu and depending on the user's choice my plot would change. Isn't there any way to extend the figure's contents upto the whole figure window?

try putting this before you plot:
axes('Units', 'normalized', 'Position', [0 0 1 1])
again, plot on everything separately, try not to use copy.
Here is an example of the command I gave: This is normal plotting:
figure
x = 0:pi/100:2*pi;
y = sin(x);
plot(x,y)
This is where the plot fills everything:
figure
x = 0:pi/100:2*pi;
y = sin(x);
axes('Units', 'normalized', 'Position', [0 0 1 1])
plot(x,y)
lemme know if you have any other trouble
