Hi,
I don't know if this can help you, but in the 1980s I worked with a
library called GKS (graphic kernel system)
which I used to build such graphics like the following example:
http://bernd-oppolzer.de/fdynsb.pdf
This programs that did this were written in Pascal at that time.
It still works today for me (the customer still uses this software),
although is it C today, and GKS is not available any more.
What I did: the original GKS calls are written to files (some sort of
GKS metafile, but not the
original 1980s format), and then this file format is read by a C program
GOUTHPGL,
which translates this (proprietary) format to HPGL. The HPGL files are
either sent to
HP plotters or translated to PDF using public domain software; see the
file above.
(GOUTHGPL was a Pascal program in the 1990s, too).
IMO, you could easily write the "GKS metafile format" with Pascal;
in fact, it is simply is a sort of logfile of the GKS calls.
Here is an old paper about the GKS system:
http://nsucgcourse.github.io/lectures/Lecture01/Materials/Graphical%20Kernel%20System.pdf
The translator GOUTHGPL supports only a small subset of GKS; see again
the example picture above.
If you are interested for more details, you could contact me offline.
Kind regards
Bernd

Hi,
I am looking for a simple to use non-visual graphing library to
produce x-y plots in a raster file format (similar to how pyplot
works). Rather than developing something from scratch or writing a
wrapper to GNU plot (additional dependency), I was hoping something
like this already would exist that I could build upon.
Thank you for any tips!
Rgds, Darius
