Is there a way to have two colors of text on an axis label? I am 
trying to plot sales dollars and margin dollars on the same graph in 
different colors. That works well enough but I'm having a hard time 
labeling the yaxis
plot_date(dates,units,visible = False)
bar(dates,sales,width=5.0,color = salesColor)
bar(dates,margin,width=5.0,color = marginColor)
ylabel("Sales $\nMargin $",color=salesColor)
gets me "Sales $" in the proper color but I can't figure out if it is 
possible to have "Margin $" in its color as well.
Thanks!
John

Does a LineCollection generated by contour() have a property that 
holds the labels? I would like to label my contour lines with roman 
numerals, and cannot figure out how to get clabel to do that.
Thanks,
Mike

I've been trying to set the font properties of the plots that I've
been making with matplotlib; however, there appears to be a problem
with font rendering. For example, when I check the properties of text
on the axes, etc, the font class is set to serif; however, the font in
the plot does not appear to be serif. I ran several of the font demos
in the matplotlib examples directory, and the fonts all looked the
same (except for size). Attached is the PNG of the fonts_demo.py
output.
The only way I was able to get serif fonts was if I call:
rc('text', usetex=True), and even then this only changes the fonts on
the axis tick labels. xlabel, ylabel still remain sans-serif.
I'm sure I am missing something obvious, but have read through all the
documentation available on the matplotlib website regarding fonts, and
they don't seem to indicate that I need to install anything else.
This is Python 2.5 on Windows XP.
Thanks,

I came across this today and thought there might be interest in this on 
the matplotlib list.
"reinteract" is an edit-in-place shell, that includes rudimentary 
matplotlib support.
http://fishsoup.net/software/reinteract/
It's still in its early stages, but the approach seems very promising. 
Be sure to watch the screencast past the half way mark where the author 
demonstrates the matplotlib integration.
Cheers,
Mike

No, it just means that ipython can run in conjunction with the major
GUI toolkits in a non-blocking manner. In a plain python shell, if
you open a plot window (for any backend other than Tk), you can't go
back to the prompt and keep typing until you close the plot. IPython
allows that to happen, with Wx, GTK, Qt and Qt4.

Mike: Create an axes instance (before drawing anything with your basemap instance) like this:
fig = pylab.figure(figsize=(X,Y))
ax = fig.add_axes([0,0,1,1])
X and Y need to be set to the desired width and height of your figure in inches. To avoid having any border, Y/X must be exactly equal to the aspect ratio of the map projection region (which you can get from the 'aspect' Basemap instance variable).
