Hi all,

I want to delete an object I created in a plot using the delete button. I created a GUI with a plot plotting a figure as described by the following:

t = 0:pi/5:2*pi;
figure
patch(sin(t),cos(t),'y')
axis equal

Now how should I delete it using the delete button?

Thanks

Viv

What do you want to delete? Do you want to delete the whole plot? Close the figure?

Why do you want to use the delete button? Why not close, or alt+F4?

Hi Mahdi, I want to delete the polygon object inside the plot and not the plot itself.

Thanks

Use the figure KeyPressFcn or WindowKeyPressFcn callback. Test the received key. If it is the delete character, then delete() the object handle.
