[Gnuplot-py-users] PlotItems issues

[Tom P. <pa...@te...>]

Hiya,

While trying to do some plotting recently, I discovered that you can't 
use the smooth argument with Func() PlotItems. Digging through the 
Gnuplot.py code showed me that various options (index, every, using, 
smooth) were only defined for FileItem's and subclasses, which Func 
isn't. As they should all be options of the top-level PlotItem, I've 
attached a patch that moves all those options to PlotItem from _FileItem.
