Hi list,
is there a way to fill continents with basemap an then use contourf to
draw filled contours over the continents?
Its useless when the filled contours cover the whole map, but when only
parts of the map are covered with filled contours, it would be nice to
paint over the continents (but still let the coastlines and countries
shine through the filled contours).
Thanks for any hints

Simon: I just added a zorder keyword to fillcontinents in basemap SVN:

You can now set zorder=0 if you want contourf to paint over the filled
continents.
