I don't even know where to begin. This is just bizarre. I just picked
up the Gnuplot.py module (a light interface to gnuplot commands) and
was messing around with it today.
I've got a tiny script, but it only works from the command line about
half the time! In the python interpreter, 100%. Ipython, 100%. I'm
not kidding.
#!/bin/env python
import Gnuplot
g = Gnuplot.Gnuplot(debug=1)
g.title('A simple example')
g('set data style linespoints')
g('set terminal png small color')
g('set output "myGraph.png"')
g.plot([[0,1.1], [1,5.8], [2,3.3], [3,100]])
Here's just one example -- it does not work, then it works. It seems
totally random. It will work a few times, then it won't for a few
times...
bash-2.05b$ ./myGnu.py
gnuplot> set title "A simple example"
gnuplot> set data style linespoints
gnuplot> set terminal png small color
gnuplot> set output "myGraph.png"
gnuplot> plot '/tmp/tmp5LXAow' notitle
gnuplot> plot '/tmp/tmp5LXAow' notitle
^
can't read data file "/tmp/tmp5LXAow"
line 0: util.c: No such file or directory
bash-2.05b$ ./myGnu.py
gnuplot> set title "A simple example"
gnuplot> set data style linespoints
gnuplot> set terminal png small color
gnuplot> set output "myGraph.png"
gnuplot> plot '/tmp/tmpHMTkpL' notitle
(and it makes the graph image just fine)
I mean what the hell is going on? My permissions on /tmp are wide open
(drwxrwxrwt). It does the same thing when I run as root. And it
_always_ works when I use the interpreter or interactive python.
Any clues would be greatly appreciated. I'm baffled.
