gnuplot-py-users Mailing List for Gnuplot.py

Hi,

Thanks to all for reply. I solved that problem.

Now I am facing one new problem. When I am using "set terminal postscript
enhanced  color " to save the graph in .ps for multi plotting (three curves
in one page ) the curves are coming deferent color but the lines are not
solid even I declared that  g('set data style lines').

Thank you
Shibnath

I suggest you start by running the demo:

    python demo.py

and looking at the heavily documented source code of demo.py to learn
the basics.  After that you can read the documentation strings in the
other Gnuplot.py modules, especially _Gnuplot.py and PlotItems.py.

Hi,

It looks like you are passing Python file handle to g.plot().

If you are trying to plot data in a file, I think it expects
Gnuplot.File object. I don't know if it will handle a string of
filename automatically, since a string could be an equation as well.

Look at help(g.plot) and help(Gnuplot.File) for more information.

Regards,

Andrzej

Hi,

I am new to python and gunplot.py . But I am quite familiar with Gnuplot. So
in Gnuplot to plot a file I used  " gnuplot> plot "filename" using 1:2 with
lines ". The file is in text form and the data are saving there in two
column 1st one is x axis and 2nd one is Y axis.

In Gnuplot.py  I try to plot same file like this "

from numpy import *
import Gnuplot, Gnuplot.funcutils
g = Gnuplot.Gnuplot(debug=1)
g.title('A simple example') # (optional)
f = open('filename', 'r' )
g.plot(f, using = (1,2), with_='lines')
raw_input('Please press return to continue...\n')


But I didn't get any plot.
So please help me.

Thank you in advance.
