Hi,

is there any method which I haven=B4t found yet in gnuplot.py to get =
what=20
would otherwise be printed on stdout?

What I actually want to do is to set my terminal to png and have the=20
binary-png-code stored in a string instead of a file or piped to=20
stdout.

I treid something like:

p=3DGnuplot.Gnuplot(debug=3D1)
p('set terminal png')
oldstdout=3Dsys.stdout
output=3DcStringIO.StringIO() # IO-String instanzieren
sys.stdout=3Doutput # stdout nach output umleiten
p.plot([[1,0],[2,50],[3,0],[4,20],[5,0],[6,30],[7,70], [8,70], [9, 75],=20=

[10, 50], [11, 30], [12, 50]])


sys.stdout=3Doldstdout
print output.getvalue()

But unfortunatelly I also get other stuff like
"gnuplot: unable to open display ''
"gnuplot: X11 aborted"

Can anyone help me on that?

Thanks,
Nicola
