[Matplotlib-users] matplotlib - fill open path inside U.S. borders

[Isidora <is...@ju...>]

Hi,
I am trying to plot filled paths over a U.S. map.  I plot the given paths, but since these are not closed paths, the filling is truncated at a line drawn between last and first point in the path.  I want to extend the path to the United States border instead.  


I am no expert in matplotlib or GIS.  Could anyone help me find documentation or blogs discussing this type of issue? I am convinced somebody else has already faced this problem although I have not been able to find any paper, documentation, blog on it. 

Thank you
