Sorry I can't reply to the exact thread, I just joined the list.
I had this problem today and my solution was to use eval():
# plot contents of dKGrid[][] against xKGrid[]
pobj = Gnuplot.Gnuplot()
# Snipped out formatting stuff...
gpd = [] # Array of plot objects.
gpdStr = "" # String listing them as arguments
for i in xrange( 0, len( yKGrid ) ):
# Make a list of plot objects
gpd.append( Gnuplot.Data( xKGrid, dKGrid[i] ) )
if i > 0: gpdStr += ", " # Comma separate them ...
gpdStr += 'gpd[%d]' % (i) # as a list of arguments
eval( 'pobj.plot( ' + gpdStr + ')' ) # Execute the plot command
pobj.reset()
Bit late, but I hope this helps...
