It sounds like you are defining the variable "inc" in Python but then
expecting gnuplot to know how to put it into a string.  Either you have
to define the variable in gnuplot or you have to do the string
interpolation in Python.

You might try the "debug" option to the Gnuplot constructor to see what
commands it is passing to gnuplot.  That might make the situation clearer.
