Hi,
I recently tried to do a contour plot with a reduced xrange,yrange and
found that PV-wave plotted the co-ordinate box ok, but proceeded to plot
the contour over the co-ordinate range out to the window edge.
I tried using the `Clip` keyword ,Clip=[Xmin,Ymin,,Xmax,Ymax] in data
co-ordinates but nothing plotted at all.
If anyone has any ideas, or if this a known bug please let me know.
Thanks.

The problem is that's with idl 5.0 minvalue and maxvalue are interpreted
wrong.
They will change it by idl5.1
You have to adjust minvalue a bit lower and maxvalue a bit heigher,
because at the moment they are interpreted in this way: values only between
(not equal) them are legal.
