The plplot tcl matrix bindings are pretty simple, and don't support what you're trying to do. It would be very cool if they did. :) A much more capable tcl matrix facility has been on my wish list since '95, but I haven't done anything with them for years. I did find scripting gui capabilities to be much nicer for its immediate feedback. Some of the stuff one might support includes slicing as you've mentioned, subranges, etc. Then at least it'd be just a few lines to do a copy & plline call, without changing the bindings. But instead you'll need to do an element-by-element copy to a 1-d matrix. -- Maurice LeBrun ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
