Re: [Gnuplot-py-users] problem with calling a file.

[Andrzej N. <no...@gm...>]

Hi,

It looks like you are passing Python file handle to g.plot().

If you are trying to plot data in a file, I think it expects
Gnuplot.File object. I don't know if it will handle a string of
filename automatically, since a string could be an equation as well.

Look at help(g.plot) and help(Gnuplot.File) for more information.

Regards,

Andrzej
