Anybody can tell me why this file isn't working right? -- Even a Smile is charity :) - Prophet Muhammad |

When I take the following script and run in python, I get gnuplot errors
for the data file shown below (shortened version). Any body able to see
what is wrong with my plot call?
import numpy as np
import Gnuplot, Gnuplot.PlotItems, Gnuplot.funcutils
fobj = open("rwtc", "r")
x, y, z = np.loadtxt(fobj, delimiter=' ', unpack=True)
g = Gnuplot.Gnuplot()
g.title('RW Speed vs Time NM ')
g.xlabel('time')
g.ylabel('speed')
g('set term png')
g('set out "run.png"')
g.plot(Gnuplot.Data(x, using='1', with_='line', title="x"),
Gnuplot.Data(y, using='2', with_='line', title="y"),
Gnuplot.Data(z, using='3', with_='line', title="z"))
You can use this as the file rwtc

Hey,
I am not fully sure if I understand what you are trying to do, but
"using 1" does not really make sense. If you plot 2D- you have to
specify at least 2 columns, like "using 1:2".
Are you trying to do a 3D-Plot?

Doh, stupid mistake, I figured it out, once I assigned the values to x, y
and z using np.loadtxt, I don't need the using 1, etc..
I am not good at python but this was my first foray into writing the code.
Now, I got a script that parses a massive file, extracts the data and
generates a plot all from the command line.
#! /usr/bin/python
#import sys
import numpy as np
import Gnuplot, Gnuplot.PlotItems, Gnuplot.funcutils
fobj = open("rwtc", "r")
x, y, z = np.loadtxt(fobj, delimiter=' ', unpack=True)
g = Gnuplot.Gnuplot()
g.title('Dellingr RW Speed vs Time NM ')
g.xlabel('time')
g.ylabel('speed')
g('set term png')
g('set out "run.png"')
g.plot(Gnuplot.Data(x, with_='line', title="x"),
Gnuplot.Data(y, with_='line', title="y"),
Gnuplot.Data(z, with_='line', title="z"))
