Michael: And one more - contourf will die if you there are no contours
at the requested levels. The error message looks like this:
Traceback (most recent call last):
File "plotprecip.py", line 52, in <module>
cs = m.contourf(x,y,data,clevs,cmap=cm.s3pcpn)
File "/Users/jsw/lib/python/matplotlib/toolkits/basemap/basemap.py",
line 2425, in contourf
CS = ax.contourf(x,y,data,*args,**kwargs)

To trigger this, try running the plotprecip.py basemap example.
