Re: [Gnuplot-py-users] Suppress visual plot, but still save hardcopy

[Conor R. <con...@gm...>]

Using iCy-fLaME's suggestion I threw this together.

Example:

#directory I want to save to as str
fdir = geo+'/'+str(hidden)+'/'+trial+'/%netval.eps'

#set output add quotes
g1('set output '+'"'+fdir+'"') #note there was an extra 'set' (typo)
in previous example

#set terminal
g1('set terminal postscript landscape enhanced color')

#plot
g1.plot(r12, r1, Gnuplot.Func('-x + 1', title = "ave response%"),
Gnuplot.Func('x', title = "ave cut%"))

This seems to work well.  Is this efficient, or what you refer to by
'set manually before plotting' ?  I'd like to tighten up the time it
takes for report generation albeit a negligible % of the process time.

Thanks
Conor
