Here's a code segment that works for me:
vmin,vmax=(280,305)
norm = colors.normalize(vmin = vmin, vmax = vmax, clip = True)
cmap=matplotlib.cm.jet
cmap.set_over('salmon', 1.0)
cmap.set_under('black', 0.25)
contplot = axes.contourf(pv.time_value,
pv.pressure_value,
pv.var1_value,
n.arange(vmin,vmax,2.),
norm=norm,
extend='both',
cmap=cmap)
I got the hint on this from the contourf docstring
***** New: *****
* extend = 'neither', 'both', 'min', 'max'
Unless this is 'neither' (default), contour levels are
automatically added to one or both ends of the range so that
all data are included. These added ranges are then
mapped to the special colormap values which default to
the ends of the colormap range, but can be set via
Colormap.set_under() and Colormap.set_over() methods.
To replace clip_ends=True and V = [-100, 2, 1, 0, 1, 2, 100],
use extend='both' and V = [2, 1, 0, 1, 2].
