Dear matplotlib developpers,
I use matplotlib for several years and I'm very satisfied with the it.
I started using the basemap package a few days ago, and I noticed something
that looks like a bug :
With the Mollweide projection (and others too), when specifying rsphere=1.0,
the coastlines is not drawn in the
left part of the plot. With rsphere=2.0 the hidden part is smaller, and with
rsphere=10.0 it is not visible.
I'm using matplotlib 1.0.0 and basemap 1.0
To reproduce the bug :
m = Basemap(projection='moll',lon_0=180,rsphere=1.0)
m.drawcoastlines(linewidth=0.5, color='grey') # draw discrete coastlines
m.drawmapboundary() # draw a line around the map region
show()
Finally the hammer projection is missing for me :
In [5]: m=Basemap(projection='hammer',lon_0=180)
