Display Several Plots in GUI using Slider

I’m building a GUI that supposes to display several subplots. In order to display a subplot in the GUI I create a uipanel and set subplot(2,2,x,’Perent’,h_panel) where h_panel is the handle of the uipanel. Inside the code there is a ‘for’ loop and each iteration display a different subplot. I would like to have the opportunity to display all the subplots after the loop is done (using slider). Can I save the handle of each subplot or its struct array and then to redisplay it?

Get the return of the SUBPLOT, then you can save the handle to each subplot.

h=subplot(2,2,x,’Perent’,h_panel); %h is the handle to the new axes object.

What do you mean by redisplay? How do you hide it? If it's just not in focus, use AXES could bring it back:

axes(h)

I have function that create a subplot and displays it into a figure. In order to display it at GUI I changed the subplot to be displaying into uipanel (i.e. subplot(1,1,1,'Perent',h_uipanel)). The GUI code contain ‘for’ loop in case the GUI’s user want to display several subplots. The problem is that each iteration overwrites the previous subplot. I need the ability to somehow “save” each subplot (i.e h(i) = get(handles.uipanel,’Children’)) in order to allow the user to display it later by using Slider (i.e copyobj(h(i),handles.uipanel)). Theoretically I can rerun the function at each use in the slider but the running time of the function is too long and I prefer to display the subplot differently.

So you subplots are overwritten by others? I mean, for each iteration, a new subplot will cover the old one? If so, you can just hide the old subplot and just show the new one, and then show the old one when it's needed.

set(h,'Visible','off') %hide the subplot
set(h,'Visible','off') %show it

But if you have a lot of subplots, it requires a lot java heap memory to hold them.
