thanks, but I am not sure that will help. I have shown a simplified
version of my program here. I actually call other functions from the
menu buttons and I guess I want the function to make sure that if
there is something already plotted in the widget space then it clears
it and starts a fresh plot. I use widget_control, draw, get_value=win
then win.select to plot in the current window. Is there anything that
I can use here to clear the current plot? I have tried win.refresh.
