Hi there,

I'm having a problem in my code. I save a graph in a function, but i need to recovery this graph to plot in my GUI element axes. How can I do this without using global?

Thanks

What is your coding to "save a graphic" ? I can think of several different meanings for that.

Did you edit the question to say " I save a graph in a function, but i need to recovery this graph to plot in my GUI element axes. How can I do this without using global?"

Or was that the original question? I'm not sure what your edit was, and the answers so far don't seem like they would apply with your current post.

If you saved it as a .fig, just use open() (I think).

If you saved the graph as an image, use imread() and then imshow().

If you saved the individual variables to a .mat file with save(), then use load() and replot everything using plot() or whatever functions you used the first time.
