Hello, I am having a few issues interfacing gnuplot with python. When I try to run the demo.py file I get the following error messages:


Traceback (most recent call last):
  File "C:\Program Files\Common Files\dSPACE\Python25\lib\site-packages\Pythonwin\pywin\framework\scriptutils.py", line 310, in RunScript
    exec codeObject in __main__.__dict__
  File "C:\Program Files\Common Files\dSPACE\Python25\Lib\site-packages\Gnuplot\demo.py", line 110, in <module>
    demo()

    g.reset()

    self('reset')
  File "C:\Program Files\Common Files\dSPACE\Python25\Lib\site-packages\Gnuplot\_Gnuplot.py", line 210, in __call__
    self.gnuplot(s)

    self.write(s + '\n')
IOError: [Errno 22] Invalid argument

After reading other users having similar problems, I altered the 'gnuplot_command' line in gp_win32.py to 'gnuplot_command = "c:\Program Files\wgnuplot\bin\pgnuplot.exe", in an attempt to directly get the pgnuplot.exe(which I believe is the root of the problem). However, I still get the same error message. Any ideas on how to solve this?

Thanks
