In the screenshots area - look for the example titled "pcolor_demo.py" - seems close enough to what you want to get you started. http://matplotlib.sourceforge.net/screenshots.html Also have a look at the Axes() and Figure() classes (type help(Axes) at the python prompt), to get more fine-grained control over the axes and legend. to get PostScript, just type savefig("my_plot.ps"), instead of show() And - this is a python package - so you can easily import data from almost any format you like. ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
