[Matplotlib-users] eps/pdf/svg contourf contours don't overlap properly with high resolution data

[Jordan D. <jd...@eo...>]

I have a bug that I am seeing with a default ubuntu 9.10 matplotlib 
install, version 0.99.0.  Contourf plots that I output in vector format 
files have little triangular glitches at the contour boundaries if the 
contoured array is larger than about 200x200.  The same files in png 
format are perfect, even at very high dpi values.  Attached is a sample 
script, and the png and eps output it generates on my machine.  I'm 
trying to make eps files for a paper, and this is driving me nuts.  Any 
ideas?
