[Gnuplot-py-users] Handling NaN-values

[Felix S. <fel...@ui...>]

Hi there,

i got a question on how to best handle NaN values.

I'm plotting 3 x-y curves into one plot (data comes from 3 files which 
are read and processed earlier in my code).
Sometimes one of them has NaN-values at the y=0 point. If i just convert 
the NaN-values as everthing else:

data_array.append(float(THENANVALUE))

the data array contains the nan and my values just fine. However if i 
then proceed to g.plot(...), i get a

line 0: Bad data on line 1

error.

What i would like to have, is a plot where the undefined lowest value is 
ignored and plotting starts at the first defined value.

Is there a simple solution to this/ any suggestion?

Thanks in advance for any answers! :-)

Felix
