stippling or cross hatching in contour plot [message #56149]

I have a couple of maps (contour plots with filled, colored contours)
that I'd like to overlay with stippling or hatching without blocking
the color underneath. Does anybody have a suggestion on this problem?
I'm trying to mark areas with high or low significance in the plot. A
simple contour doesn't work very well since the data is pretty noisy,
and I end up getting a lot of lines.

The only way to hatch things that I've found is with the c_orientation
keyword in the contour procedure. My problem with that is that it will
always hatch above the topmost defined level. I.e. if I want to hatch
between values of 25 and 50, and set levels=[25,50], it will hatch
above 50 as well. Also, it erases the colors underneath the hatched
portions.

Or should I use polyfill instead? I've done stippling before by
defining a pattern for polyfill. I think this would cover over the
underlying color contours, too. Unless I redefine the pattern in each
box with the correct color...

Any suggestions?
Thanks!
