Yes, pcolormesh works great. Still, when I use the default values [pcolormesh(x, y, z)] I get a Morrey (sp?) pattern instead of seeing the grid -- i.e., better than pcolor(..., shading='faceted'), but still not a great plot. Is it possible to set RC defaults to get the equivalent of shading='flat' in pcolormesh? As far as I know, it is not possible in pcolor. -r ---- Rob Hetland, Associate Professor Dept. of Oceanography, Texas A&M University http://pong.tamu.edu/~rob phone: 979-458-0096, fax: 979-845-6331 ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
