Hi Giovanni,

I tried it on my computer, but had some problems to make it run,
and I still have various error messages. These problems can
probably be solved by putting your code in a clean TeXmacs plug-in
(see Help -> Interfacing ; you just need to bundle your files
following the conventions that are explained there).

Concerning your problem with text: you may change the alignment
using TeXmacs markup. To see how, and similarly for other types
of markup, you may draw a picture with horizontally centered text
in graphics mode, and look at the source code representation
(Document -> Source -> Edit source tree).

Best wishes, --Joris

I have written a small set of Scheme files to plot functions using
the graphics of TeXmacs. I put it at
https://github.com/pireddag/plotFun, with short instructions on how
to use it.

The code can be improved a lot and it is not well-documented (I am
starting already to forget what I wrote in there); for example the
plot parameters (at the moment they are the function and the range)
could be supplied with a file rather than as parameters of the
macro; and of course writing the function to be plotted in standard
notation would also be nice, but I do not have time for this
immediately.

I would appreciate, though, if someone tries it and tells me whether
it works on their computer.
A thing that I would like to improve is the placement of the tick
labels: I think that to place them right I should know how long each
typeset string is, but I do not know how to get this information and
to pass it onto the Scheme code. I would appreciate suggestions on
this too.

Giovanni
