OK, I have figured out how to create a fake image
that gives me the proper colorbar now.
Now I have some questions about MapGrid.
The spacing of the latitude and longitude lines in my
map grid are too close together. I read the documentation
and I see the keywords GRID_LONGITUDE and GRID_LATITUDE
are to be used to set the "grid spacing in degrees."
So, OK, I define my grid like this:
grid = Mapgrid(Color='gray', Grid_Longitude=60, Grid_Latitude=30)
And *nothing* about the grid changes at all. :-(
Am I reading the documentation wrong, or am I still
on this incredible one in a million losing streak?
Cheers,
David
