[Matplotlib-users] ImportError: cannot import name rcParams

Hi, I'm getting the following error when trying to create a plot with matplotlib. I am using matplotlib-0.91.2 on CentOS 4 with python 2.3. We are running it with mod_python and Apache in a web service configuration. File "/usr/lib/python2.3/site-packages/matplotlib-0.91.2_r0-py2.3-linux-i686.eg

[Matplotlib-users] Prism colormap

The prism colormap repeats the same pattern over and over instead of spreading itself over the plotted data range in a pcolor plot. Is this expected behavior? Simply add prism() to pcolor_demo.py to see what I am talking about. Thanks, Rich

[Matplotlib-users] Basemap: Labeling parallels in polar stereographic projections

Hi, When using north/south polar stereographic projections from basemap, how can I get labels to show up on the parallels when none of them intersect a plot edge? Thanks, Rich - This SF.net email is sponsored by: Microsoft

I'm plotting some grid data using pcolor, and trying to get canvas pixel locations of data points using the ax.transData.xy_tup() method. I am saving these figures to PNG files using the default Agg backend. When I open these images up in Gimp and check the pixel locations, the X pixel locat

[Matplotlib-users] Basemap, Mercator Projection and pcolor

Hi, I've successfully plotted gridded data on a basemap "cyl" projection using pcolor: mp = Basemap(projection="cyl", resolution="l", llcrnrlon=0.0, urcrnrlon=30.0, llcrnrlat=-5.0, urcrnrlat=5.0) pc = mp.pcolor(X, Y, zvalsm, cmap=cm.jet) However, if I simply I change the projection type to m
