Thread Subject: Dragging a selection square on a plot?

Hello,

suppose you have a figure with some plot. I would like the user to be able to drag a little selection square in some area of the plot. After the selection has been performed, I would like to obtain the x1,x2,y1,y2 coordinates of the square and e.g. perform an new computation of the plot with in the new coordinates. This is not supposed to be a simple zoom (like the magnification glass from the toolbar) as I want to recompute the plot to obtain a higher precision.

The plot I am talking about may possibly be within a solitary figure like created by a figure(1) command, or possibly an axis within a GUI figure.

I am quite sure that there must either be a very simple way to do this, or someone has written the code already. So I'd be greatful for some help.

Regards,

Alexander

Have you tried RBBOX or DRAGRECT?

Good luck, Jan
