JJ Thanks for the tips. I had seen one of those posts whilst googling around for the bug, but discounted it because I'm not using an alpha value.
Here are links to one of the cookbook examples, and one of the files that I want to plot: http://files.getdropbox.com/u/533499/griddata-test.png http://files.getdropbox.com/u/533499/silicon_donor_10_newplot.png I'm using Mac OS 10.5.7, Python 2.6.2, and MPL 0.98.5.3. I don't know which bug in the thread you were referring to. I tried the >>> for c in CS.collections: c.set_edgecolor("none") fix, but it didn't have any effect.
