Re: [Gnuplot-py-users] plotting multiple plots at once..

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"))
