please commit the Plotdf.tcl patch that I sent you, but wait for
a plotdf.lisp that I will send you later on today.

once you patch the tcl scripts you can already use plotdf directly from
omplotdata with something such as:

# omplotdata "plotdf" -dydx "exp(-x)+y" -trajectory_at "2 -0.1"

However, Tkmaxima's parser for the functions you enter in -dydx, -dxdt or
-dydt is very buggy and will not understand maxima's terminology (no %e, %pi,
etc). With plodf.lisp those functions will be parsed by maxima and passed
to Tkmaxima in a form it understands.
