On a related note, I saw a seminar last week in which the speaker
had beautiful XY plots with different regions done in different colours.
When a plot line indicates a dividing line between different regions of
interest, the use of colour is a great aid to understanding.

The question is: how can one achieve this in IDL? I am interested in
writing a very general object that takes sets of XY plot data and can
fill interior regions with different colours. This amounts to: given
sets of lines and a bounding box (the axes), locate all the closed
polygons.

Comments?
