[Matplotlib-users] Clip or skip lines going over border of canvas

2014-03-07 Thread svebert 
Hi!

I plot measurment data and connect them with lines (style eg. -*r). Points
which are outside of the ylimits are still connected with points which are
inside of the ylimits. Is there any way to tell matplot to only connect two
points if both are inside the y/x-limits?
Because now i get weird lines crossing the whole canvas if some points
spread to much from the mean data.

Removing points before plotting is not an option because then points are
connected which are not in consecutive order. Matplotlib should just skip a
connecting line when one of the two points lies without the canvas/limits.

Is there any simple way/option to do tha?

Thanks in advance,
Sven

It sounds like what you need to do is either use a masked array and mask 
out the points that are outside the limits, or use NaNs for that purpose.
