[Gnuplot-py-users] Plot list of PlotItems

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

Hi there,

i have following problem:
i want to plot a number of lines. The number of lines can be set by an 
user option, so i don't know it in advance. I thought of using a list of 
Data PlotItems. Establishing the PlotItem list works, however sending it 
to g.plot fails. Any idea how to do this/ work around it.

Here's a testcode to illustrate what i mean:

   1 import Gnuplot
   2 from numpy import *
   3
   4 g = Gnuplot.Gnuplot(persist=1)
   5 g('set terminal x11 size 1000,680')
   6
   7 y = []
   8 y.append([1,2,3,4,5,6])
   9 y.append([1.1,2.1,3.1,4.1,5.1,6.1])
  10
  11 ga =[]
  12 ga.append(Gnuplot.Data(y[0],binary=0,with_='lines'))
  13 ga.append(Gnuplot.Data(y[1],binary=0,with_='lines'))
  14
  15
  16 # --- This of course works---
  17 #g.plot(ga[0],ga[1])
  18
  19 # --- This is what i want to work :-) ---
  20 g.plot(ga)


Looking forward to your answers!

regards,
Felix
