Hi Robert,
sorry for the late reply. I created all the figures currently
in that directory. For each figure to be included in the manual
you need to create two versions: PDF and GIF. For example,
figure_name.pdf and figure_name.gif

To add that image to the manual, you use, in the info file:

@ifnotinfo
@image{figures/figure_name,8cm}
@end ifnotinfo

in the translations that should be
@ifnotinfo
@image{../figures/figure_name,8cm}
@end ifnotinfo

The PDF manual will use the PDF file and the HTML manual will
use the GIF file.

To create the PDF files I created a PostScript image file from
Maxima, and then made a few changes to make the Gnuplot images
more readable.
I used the Python script that I send you in an attachment, in the
following way:
  fixgnuplot.py old_file.ps > new_file.ps
but different graphs needed different manual adjustments. I put
the modified PostScript files in the repository so you can see
the changes using diff with the file created by Maxima/Gnuplot.

To transform the PostScript files into PDF I used ps2pdf, and
to obtain GIF from PS I used convert, from Imagemagik.

I hope this answers your question. If you think it is worth publishing
this information somewhere, let me know.

Regards,
Jaime
