Hi folks,

I have a 3D figure on which I placed some popup menus. The plot is a function of whatever the user pulls down from the popups, so how do I redraw the whole figure to update it (using a function), without destroying the figure, or creating many duplicate figures?

Thank you for helping me.

Dave

Once you have a surf or plot3, to draw the new plot, update the XData, YData, ZData properties of the graphics object.

Or at most use cla() to clear the axes. Do not use clf().

Thanks. cla() was easier since there's too much complicated data on the figure, and it's easier to recalculate the whole thing anyway.
