strange contour plot

It looks like this bug has been fixed on the SVN trunk. Unfortunately, these changes were pretty major surgery, so they don't easily apply to 0.98.5.x. Unfortunately, for the time being, it looks like you'll need to wait until the next release, or compile matplotlib from SVN yourself. I haven't heard any concrete plans about the next release yet.

Cheers,
Mike

I haven't tried that as I didn't realize there was an issue there. I'm fairly new to matplotlib and am definitely still learning how to use it. Thanks for your help with this, I've attached 3 data files and the test script. Please let me know what you find (and feel free to comment on the code if there is an easier way to do something).

    You might be running into one of the path simplification bugs in
    the 0.98.x series. Have you tried with the rcParam path.simplify
    turned off? If you can sent me a self contained script and data
    off-list, I can test this against the SVN version to see if this
    has already been addressed.

        I'm having a strange problem with my contour plots and I'm

        plots with the data mirrored over the x-axis. This seems to
        work fine most of the time, but every now and then I get a
        plot that seems to just ignore a couple of data points when
        creating the contours. I've attached a plot of what I mean.
         Looking at the arrays the contour plot is created from
        doesn't show any obvious problems (there are values there that
        should be plotted). It's very strange, any ideas?

        matplotlib 0.98.5.2
        numpy 1.2.1
        python 2.5.1
