Ploting gnucap simulation data with gnuradio

GNU Radio
1

Hi,

I have some data from a gnucap charging capacitor simulation and want to
plot it with gnuradio.wxgui.plot.
Has someone a python example code How to read the data produced from
gnucap
in to make gnuradio.wxgui.plot plotting it out?
So I think I have to use something like PolyLine(data1, legend=
‘charging
capacitor’, colour = ‘red’)
but how can I fill a python sequence,array,tuple or list with my gnucap
data?
My data from gnucap looks like this:

#Time v(C1)
0. 0.
0.01 0.46406
0.02 0.92923
0.03 1.3717
0.04 1.7926
. .
. .
0.98 9.9254
0.99 9.9291

  1.                    9.9325

e
0. 0.
0.01 0.04768
. .
. .

Is there something ready for use in gnuradio which do the task? Or do I
have
to read the data in with the python file functions
(open, read, readline)

The plot.py file in gnuradio.wxgui is something ported over to use
within GNU Radio for the internals of the graphical flow graph
instruments–it’s not really something intended for general use. You
could see how it’s used by our scripts and do that yourself if you
wanted, though.

I recommend reading and parsing your input file with Python file
functions, then plotting it with the matplotlib library.

How about just using matplotlib?

i used matplotlib with my ber experiment and it is a very powerful
library…i really incourage you using it :wink:
