[Gnuplot-py-users] Plotting problem in python

My previous installation problem is now solved. Hurray! But, now I have a=
 new problem. Trying to=20
actually plot in python brings up a string of errors. My code goes as suc=
h (as per the instructions in a=20
manual I was given):

from Gnuplot import Gnuplot, Data
graph =3D Gnuplot()
results =3D Data(xx, yy)
graph.plot(results)

The arrays xx and yy have been previously defined. It's the last line tha=
t brings up the errors, which are:

Traceback (most recent call last):
  File "<pyshell#3>", line 1, in -toplevel-
    graph.plot(results)
  File "/Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/s=
ite-packages/Gnuplot/
_Gnuplot.py", line 274, in plot
    self.refresh()
  File "/Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/s=
ite-packages/Gnuplot/
_Gnuplot.py", line 215, in refresh
    self(self.plotcmd + ' ' + string.join(plotcmds, ', '))
  File "/Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/s=
ite-packages/Gnuplot/
_Gnuplot.py", line 199, in __call__
    self.gnuplot(s)
  File "/Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/s=
ite-packages/Gnuplot/
gp_macosx.py", line 136, in __call__
    self.flush()
IOError: [Errno 32] Broken pipe


I have no idea how to fix this. Once again, any help is very much appreci=
ated.
