[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.

It looks to me that it doesn't even find gnuplot.exe
Is this executable in the executable path ?. It must be. 
Otherwise you can specify the full path to the gnuplot_command
in your system (but you will need to do that for each
release)

I do not run windows, but I changed the gnuplot_command to a 
non existent name in my Linux box and I get an error message
somehow similar to yours. 

Best luck,

Dear Gnuplot-py-users,

I found this problem was a know issue and discussed at support page
(http://sourceforge.net/tracker/index.php?func=detail&aid=416091&group_id=17434&atid=217434).

Gnuplot.py works on win32 by following instruction in this support page.
