Hi,
maxima-online.org will not work with plotdf, because they are forcing 
all plots to be done with Gnuplot,  and they add some specific terminal 
(I guess png?) using gnuplot_term. plotdf only works with Xmaxima as the 
graphic driver, rather than Gnuplot, and it depends on the tcl/tk 
toolkit in Xmaxima to work as an interactive program. I know it is easy 
to use tcl programs as cgi scripts via Web, but I do not know whether it 
would  be possible to put xmaxima on-line or not (just as a graphics 
driver, not as a command interface). You should report this problem to 
the administrators of maxima-online.org.

Regards,
Jaime
