Re: [Matplotlib-users] contour_demo.py

[Eric F. <ef...@ha...>]

I don't recognize the error output at all, but it looks like you have an 
old version.  The current release is 0.87.7.  I don't know of any 
released version in which contour_demo.py did not run at all, though.

The X errors make me wonder whether you are trying to run from inside an 
IDE.

My suggestion would be to delete the installation you have, do a fresh 
install of the current version, and then try running demos on the 
command line, making sure the demos are from the newly installed version.

If you still have a problem, tell us what version you are running, how 
it was installed, and on what kind of system.
