matplotlib-devel Mailing List for matplotlib

That's a great suggestion. I'm not familiar at all with the doc test 
extension, so the plot directive doesn't do this. It gets a fresh 
namespace (though not a fresh interpreter) for each plot.
To avoid complicating the merge further, I'd like to wait for Pauli 
Vertanen's merge of the new plot directive features from Numpy back into 
matplotlib before looking at implementing this. It will probably just 
involve inheriting/emulating whatever the doctest extension is doing to 
make that work. And if the directive is used in the old way (providing 
a filename), we'll just clear any state at that point.
