[matplotlib-devel] NaN support

[Darren D. <dar...@co...>]

It looks like the new transforms codebase does not support data that contains 
NaNs the way the old trunk did:

plot([1,2,NaN,4,5]) produces a plot with no line break
plot([NaN,2,3,4,5]) produces a plot with no line

I know use of NaN's is not encouraged, and we have discussed it on this list. 
But since they are sometimes unintended and unavoidable, I'm reporting the 
behavior so people are not surprised when they get an empty plot.
