[Gnuplot-py-users] Problem with simple application

[Florian L. <mai...@xg...>]

Hello,
I've the python script:

import Gnuplot

g = Gnuplot.Gnuplot(debug=1)
g.title('A simple example')
g('set data style linespoints')
g.plot([[0,1.1], [1,5.8], [2,3.3], [3,4.2]]

taken from demo.py.

When I try to execute:

florian@horus ~/python $ python plot.py
gnuplot> set title "A simple example"
gnuplot> set data style linespoints
gnuplot> plot '/tmp/tmpzCyAzN' notitle

gnuplot> plot '/tmp/tmpzCyAzN' notitle
              ^
         can't read data file "/tmp/tmpzCyAzN"
         line 0: util.c: No such file or directory


What is wrong there?

Thx,

Florian

This is the well-known problem that the temporary files can be deleted 
before gnuplot is done using them.  Please see the first question of the 
FAQ.
