use: does not recognize 'aqua' Term.

I have a question about gnuplot. This may not be the place to ask this, but I don't know where else (yes, I googled for a Python forum on gnuplot, but didn't see any -- could have missed it)

Several people have recommended gnuplot (and in this email list for 3D plotting (now missing in matplotlib). So I tried it and I get the following errors when I run the

[myterm] : python

set terminal aqua
set title "A simple example"
set data style linespoints

set terminal aqua

         line 0: unknown or ambiguous terminal type; type just 'set terminal' for a list

I installed AquaTerm after getting this message (and doing some googling) and reinstalled, but I still get the message. Any clues are welcome. Thank you.
