Thanks for your answers.
I couldn't find a complete command reference for openmath. Is there any?
Googling for it is hard, since there's a completly unrelated standard
named openmath about representing math equations.

Digging in the source I found that I can execute in maxima:
:lisp (show-open-plot "plot2d -xfun exp(m*x) -sliders m=-10:10");
And that will display the graph.
I wanted to graph, for instance, e^x against it's Taylor series
expansion of different orders and see how it varies when you change the
order. I guess that's not currently possible. You'd have to make
openmath evaluate the expression in maxima and then plot it, whenever a
slider is changed.
As for what to do with gnuplot, you could either disregard commands that
can't be used there and issue a warning, or you could create a new
command which specifically uses openmath and lets you access all the
openmath goodness.
Also, I want to thank you for openmath. Plotdf is great! It helped me
understand differential equations.
Bye,
