[Matplotlib-users] plotting an array with gaps

[mdekauwe <mde...@gm...>]

Hi,

Is there a nice way to plot an array where there are say missing days and
you wouldn't want the line to join over these data gaps, i.e. show the gaps. 

E.g.

1 4.5
2 4.6
4 6.7
8 5.7
9 1.2

The only way I could think to get around this involved appending NaNs and
then masking the array, but I wonder if this isn't a tad convoluted?

thanks,

Martin

This is probably the easiest way.  You could also construct a custom
compound path and then use a PathPatch where the facecolor was set to
'None'
