I don't think there's ever been a version 1.6.1 of Gnuplot.py
released.  Are you using 1.6 or a more recent CVS version or ...?

It looks like you are using a home-cooked extension to Gnuplot.py, so
I could only guess what your problem might be.  Possibly the argument
that you are passing to gnuplot.__call__ is not a sensible string as
it should be.

If you send us more information we might be able to help you.

Michael
