min =3D 1
g.plot('%f *x+ %f'%(alfa,min))

Hi.

I've a problem using gnuplot.py. I have a python script in which I 
calculate the value of a parameter 'alfa'. After I'd like to plot the 
function f(x) = alfa*x. How ca I pass the parameter to gnuplot command?

My script is the following:
   
    g = Gnuplot.Gnuplot(debug=1)
    g('set terminal aqua 0')
    ...
    alfa = 1 + n*math.pow(sum,-1)
    g.plot('f(x) = (alfa *x+min, alfa = 1.35710030508, min=1, f(x) ')

Sorry for my english,
thank you!

Solution for Windows XP:

I had the same problem. I downloaded the Gnuplot program and it worked,
although Gnuplot.py did not, even after adding the installation path
(e.g.) to the PATH variable.

=20

I put Gnuplot in C:\Program Files\ so the directory is C:\Program
Files\gnuplot\bin

=20

I then went to my Gnuplot folder in the site-packages folder (e.g. C:\
Program Files\Python24\Lib\site-packages\Gnuplot) and edited the
gp_win32.py file.

Instead of

gp_win32.py:

=20

gnuplot_command =3D r' pgnuplot.exe'

=20

Edit it to

gp_win32.py:

=20

gnuplot_command =3D r'"C:\Program Files\gnuplot\bin\pgnuplot.exe"'

=20

and now it should work!

=20

Good luck
