It works for me.

- Are you sure you only typed those three lines into Python?  Could it
be that you set the xrange and/or yrange in an earlier command?

- What platform are you using?  What versions of Python and gnuplot?

- What is the result with debugging output turned on?:

  import Gnuplot
  g = Gnuplot.Gnuplot(debug=1)
  g.plot([[0,1.1], [1,5.8], [2,3.3], [3,4.2]])

hi. i've just started using Gnuplot-py but i've a very simple problem.

i use the exact code in the demo.py file which returns as this..

>>> import Gnuplot
>>> g=Gnuplot.Gnuplot()
>>> g.plot([[0,1.1], [1,5.8], [2,3.3], [3,4.2]])
>>> Warning: empty x range [0:0], adjusting to [-1:1]
Warning: empty y range [1.1:1.1], adjusting to [1.089:1.111]

which shows a Gnuplot window but only with one dot at [0,1.1]
it brings up the same error when a run demo.py

can anyone help?

Noob question: how do i get a contour plot with filled curves? In
Gnuplot, it seems one could say 'plot ... with filledcurves', but I
don't know how to do this in gnuplot.py.

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.
