Re: filled closed curve

[Ben Tupper <btupper(at)bigelow.org>]

Hi,

To shade the polygon on the current display (assuming you are using
direct graphics), try the POLYFILL procedure.  You should set up a
coordinate system before calling POLYFILL unless you want to draw
directly in device (pixel) coordinate space.

Something like: 

PLOT, X, Y, /NoData, /YNoZero, ...

POLYFILL, X, Y, Color = myColor, /Data
