I just found this unread in my email stack--did anyone reply to you 
already?  If not, the answer to your question is no, matplotlib declines 
to fill bad value gaps via interpolation.  We believe that as a plotting 
library, we should generally plot the data as provided, leaving it to 
the user to interpolate over gaps, if that is desired.
