[Matplotlib-users] plotting with missing data?

[Chris W. <ch...@si...>]

Hi All,

Say I have data that looks like:

date         x  y  z
2008-01-01  10
2008-01-02  21 11
2008-01-02  32 15  5

How can I plot it such that all three lines are plotted by that it's 
apparent two of them are missing some data?
(I know I could just sub in zeros for the missing values, but I'd like 
the point not to be there, not just down the bottom of the graph...)

cheers,

Chris
