What is ppgplot
Ppgplot is a python binding to PGPLOT. It was originally made by Nick Patavalis, but the location where ppgplot should be (http://ariadne.di.uoa.gr/ppgplot) is dead. I added some missing PGPLOT bindings. I also wrote a setup.py installer script to make it easier to install.

The documentation for ppgplot can be found here, but i advise to use Kplot, and not ppgplot directly.

All you have to do to install pgplot is download the tarball, extract it, and run 'python setup.py install'. You can also try the rpm, but I didn't test it.


Example

#! /usr/bin/env python

#  pgex1: freely taken from PGDEMO1.F
#
import ppgplot, Numeric
import sys

# create an array
xs=Numeric.array([1.,2.,3.,4.,5.])
ys=Numeric.array([1.,4.,9.,16.,25.])

# creat another array
yr = 0.1*Numeric.array(range(0,60))
xr = yr*yr


# pgplotting
if len(sys.argv) > 1: # if we got an argument use the argument as devicename
        ppgplot.pgopen(sys.argv[1])
else:
        ppgplot.pgopen('/xwin')
ppgplot.pgenv(0.,10.,0.,20.,0,1)
ppgplot.pglab('(x)', '(y)', 'PGPLOT Example 1:  y = x\u2')
ppgplot.pgpt(xs,ys,9)
ppgplot.pgline(xr,yr)
ppgplot.pgclos()
