[Gnuplot-py-users] problem of gnuplot-py with win32

[Hiroshi W. <wa...@ri...>]

Dear Gnuplot-py users,

I tried to run Gnuplot-py on Win32 but I got following error messages;

python demo.py
Traceback (most recent call last):
  File "demo.py", line 121, in ?
    demo()
  File "demo.py", line 72, in demo
    g.ylabel('x^2') # take advantage of enhanced postscript mode
  File "c:\python22\Lib\site-packages\Gnuplot\_Gnuplot.py", line 434, in ylabel
    self.set_string('ylabel', s)
  File "c:\python22\Lib\site-packages\Gnuplot\_Gnuplot.py", line 381, in set_string
    self('set %s "%s"' % (option, s))
  File "c:\python22\Lib\site-packages\Gnuplot\_Gnuplot.py", line 206, in __call__
    self.gnuplot(s)
  File "c:\python22\lib\site-packages\Gnuplot\gp_win32.py", line 124, in __call__
    self.write(s + '\n')
IOError: [Errno 22] Invalid argument

It seems to me that python cannot properly pass argument to
'pgnuplot.exe'.

I use
 gnuplot-py-1.6
 python-2.2
 gnuplot-3.71

How can I solve this problem? 

Thank you in advance.

Hiroshi
