I have added options so that each plot can be customized: color, line 
style, line thickness, number of points. Moreover a graph can have a 
title and labels for the x- and y-axes; the size of the graph can be set 
by the users. All options have default values (there is a cycle list for 
colors which I took from gnuplot).

There is still considerable work to do, but I think the program at the 
moment can be used for private documents. Examples of needed things are 
- improve the placement of graph elements: tick labels, axes labels, 
title; refine the size of the tick marks; exponential notation for tick 
labels; either change the input syntax or write a parser that checks it; 
add a legend; add plots of data points.

Also, to further annotate the graph once that it has been generated it 
is necessary to "ink over" it (select it and then Insert->Image->Ink 
here). To do some changes to the graph itself one has first to 
deactivate the "ink here" macro, then it will be possible to deactivate 
the plotFun macro. The third graph in the documentation (not yet in the 
file with the examples only) has an example.

I know that Joris has written a plotting utility, I am insisting with 
mine as doing it is fun :-)
