<p class="MsoNormal">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:</p>
<p class="MsoNormal"> </p>

<p class="MsoNormal">Traceback (most recent call last):</p>

<p class="MsoNormal">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?</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Thanks</p>
