[Matplotlib-users] Missing values in plots with NaN?

[Mark H. <ao...@ds...>]

Hi,

Is there any easy way of adding missing points to a (line) plot? Matlab 
can do this using NaN, but as far as I can tell matplotlib doesn't 
support this. Something like the code below would be nice, but I don't 
know if this is Numeric compatible/cross platform enough/etc?

from numarray.ieeespecial import *
plot([10, 20, nan, 30])

I guess I can do split(source array) --> a, b and then plot(a, 
linestyle, b, linestyle) but having missings directly in the array would 
be preferable if possible.
