[Gnuplot-py-users] Problem with plotting different linestyles

Hallo,

I need to plot some curves and a data point into one diagram. I can't 
find out how to tell Gnuplot to use different linestyles for different 
items ("lines" for the curves and "points" for data) when plotting from 
a python script.

E.g., if I write

g=Gnuplot.Gnuplot()
g('set data style lines'),

the plotting command for the point is not executed (naturally...).
But is there a way to give a data style different from the general on, 
e.g in the plotting command?

I tried things like
g.plot(a,b,c,k with points)
where a to c are the curves and k should be the point, but it does not work.

I would be grateful for any help.

Greetings, Jette
