Hi!
Has anyone developped a cw_widget to plot 3d contour sections where you
can change the range (xrange,yrange), the levels and the titles by the
mouse?.

I'n not sure I know exactly what you have in mind, but you can use
the DEFROI function to manually draw a contour on an image. The
code might look like this:
TV, image
s = SIZE(image)
junk = DEFROI(s(1), s(2), xvert, yvert, /NoRegion, /NoFill, /Restore)
Your "contour" will be described by the x and y points in the xvert and yvert
variables.
Cheers!
