The curve plots are done by means of GnuPlot, which generates
a Postscript, which is non-transparent. I suppose that the
curve Joris drawed in his paper was just handmade, by means
of drawing a spline in the graphics. In this latter case,
of course, one can see the grid.

This depends on GnuPlot. Or either, once the plot is done,
you can observe that GnuPlot generated a <postscript|...>
markup. You can change the dimensions of <postscript|...>
objects by means of changing the appropriate parameter (see
in the documentation for the spec of how <postscript|...>
works).

That's again a problem with how GnuPlot does the drawing.

In the future, it should not be very difficult to add
a *native* TeXmacs drawing tool, which would generate
TeXmacs graphical markup, instead of a blackbox Postscript.

We plan to write the documentation about programming
in TeXmacs in the next few months. Once it will be
done, it will perhaps become more feasible to implement
a simple Scheme example plugin for this, and let somebody
in charge of improving & maintaining it.


Best, Henri
