[Gnuplot-py-users] Plot list of PlotItems

[Cuneyt E. <cun...@gm...>]

Hi,

I wan to plot more than one curve in the same graph using same function with
different parameters. The following code works without problem.

from numpy import *
import Gnuplot

gp = Gnuplot.Gnuplot(persist=1)
x = arange(0,1,0.01,dtype='float_')
d1 = Gnuplot.Data(x, ozfonksiyon(omegalar[0],x), title='1. ozdeger',
with_='lines')
d2 = Gnuplot.Data(x, ozfonksiyon(omegalar[1],x), title='2. ozdeger',
with_='lines')
d3 = Gnuplot.Data(x, ozfonksiyon(omegalar[2],x), title='3. ozdeger',
with_='lines')
d4 = Gnuplot.Data(x, ozfonksiyon(omegalar[3],x), title='4. ozdeger',
with_='lines')
d5 = Gnuplot.Data(x, ozfonksiyon(omegalar[4],x), title='5. ozdeger',
with_='lines')
gp.plot(d1,d2,d3,d4,d5)

in this code ozfonksiyon and omegalar are user defined functions. But what I
want is to create plotitems (d1,d2,d3,d4,d5) in a for loop. I modified the
code like below,

for ii in range(n):
    datalar.append("Gnuplot.Data(x, ozfonksiyon(omegalar["+str(ii)+"],x),
with_='lines')")
gp.plot(*datalar)

I get this error.

/usr/bin/python -u  "/media/disk/doktora_tezi/tek_cubuk/python_files/CALISAN
KOD/fix_free_controlled_parametrelerin_degisimi_deneme.py"

gnuplot> plot Gnuplot.Data(x, ozfonksiyon(omegalar[0],x), with_='lines') ,

ozfonksiyon(omegalar[2],x), with_='lines') , Gnuplot.Data(x,
ozfonksiyon(omegalar[3],x), with_='lines') , Gnuplot.Data(x,
ozfonksiyon(omegalar[4],x), with_='lines')

         line 0: ':' expected

What am I doing wrong?
