I can't help you with IDL 8 function graphics, sorry.
I'll get around to fixing those in my next book. ;-)
But this is a pretty neat idea, so I just modified
FSC_Erase to have a Layout keyword like other Coyote
Graphics routines. This allows you to "erase" just
a portion of the display.
So, you can do this, for example.
FSC_Plot, LoadData(17), Layout=[2,2,1]
FSC_Plot, LoadData(17), Layout=[2,2,4]
Then, if you want to "erase" the first plot, you
just type:
FSC_Erase, Layout=[2,2,1]
I'll check this in later today with the other changes. :-)
Cheers,
David

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.

I think what you want is the p.hide property.

Hi,
In IDL 8.1 we are adding a "Delete" method to the new graphics - it
will delete just that graphic. We are also adding a GetData/SetData
method, so you can change the data on an existing graphic (like a
Plot) and all of the properties will stay the same.
For now, in IDL 8.0, you can use the undocumented "PutData" method:
p = plot(/test)
p.PutData, findgen(2,100)
The first column is the X values, and the second is the Y values.
Hope this helps!
