I have been trying to modify the custom projection example (http://matplotlib.sourceforge.net/examples/api/custom_projection_example.html) to plot a Sanson Flamsteed Projection (Sinusoidal projection).
Such a projection is defined as:
x = (long-long0)*cos(lat)
The problem is how to correctly handle the:
As the resultant plot area/plot boundaries is not circular/elliptical like the examples provided.
Does anyone, who has played with this projections, or has better understanding of matplotlib provide me with a way to handle this?
