[Matplotlib-users] quiver() color arrays?

Hey there, I'm trying to plot a bunch-o-vectors, colored red or blue, depending on whether their magnitude is positive or negative (they represent stresses), and I'm doing something like this: mag1 = evals[:,0] ex1 = evecs[:,0,1] ey1 = evecs[:,0,0] C1 = np.where(mag1 = 0, 'red', 'blue') mag2

[Matplotlib-users] Wrong download link for MPL 0.99?

For some reason the download link on the Matplotlib pages is pointing to Basemap 0.99.4 instead of Matplotlib 0.99.0. I did a clean checkout of the v0_99_0 tag: svn checkout https://matplotlib.svn.sourceforge.net/svnroot/matplotlib/tags/v0_99_0 and built/installed it, and that seems to have

Okay, so in the variables section, what you've got is a list of things which vary as a function of the dimensions listed in the previous section (time, nsr_delta, lat, lon). I don't remember which of the NetCDF file reading libraries you're using, but using Jeff's older netCDF3 interface, you

I just installed the latest SciPy Superpack in order to get access to the scipy.spatial.KDTree class, and discovered that for some reason now when I use contourf() lines get drawn at the boundaries between the filled contours. Additionally, there is always a single vertical line crossing from
