[Matplotlib-users] Plot with missing points

[Phil E. <pj...@ha...>]

Hi all,

   I am really enjoying working with matplotlib and hats off to an 
excellent effort.

   I have done a cursory search of the mailing list archives but didn't 
find the answer to a practical question that I ran into in MATLAB all 
the time (which is where I'm coming from in terms of familiarity).

   Suppose I have an array to plot, and I want to exclude certain points 
from being plotted.  In MATLAB, I would set the y vector points I wanted 
excluded to "NaN" and then the plot routine would draw connected lines 
up to the point before the excluded one, skip the bad/not wanted point, 
and then continue drawing lines beginning at the next point.

   How does one accomplish that using matplotlib?  This actually comes 
up quite often in our radar work here, in cases where we are making log 
plots of vectors which may contain zeros.

cheers,
