Individual line colors are listed in xymon/server/etc/graphs.cfg.
E.g. the clock graph line is 00CC00 (mostly green):
[clock]
TITLE Clock offset
YAXIS Seconds
DEF:offset=clock.rrd:la:AVERAGE
LINE2:offset#00CC00:Seconds
^^^
The default colors for the @RRDIDX@ multi line graphs are set in
xymon-4.3.28/web/showgraph.c:
char *colorlist[] = {
"0000FF", "FF0000", "00CC00", "FF00FF",
"555555", "880000", "000088", "008800",
"008888", "888888", "880088", "FFFF00",
"888800", "00FFFF", "00FF00", "AA8800",
"AAAAAA", "DD8833", "DDCC33", "8888FF",
"5555AA", "B428D3", "FF5555", "DDDDDD",
"AAFFAA", "AAFFFF", "FFAAFF", "FFAA55",
"55AAFF", "AA55FF",
NULL
};
You'd need to recompile showgraph.cgi to change those. I don't know if
there's any place to change those without a recompile.

Just to close the loop on this conversation, here's what I added
to my xymonserver.cfg file to get my graphs the way I wanted. As
previously stated the opts are all on one long line.

I'd still like rounded corners and I haven't figured out how to
change the graph line colors, but that's not a big deal for me at
this moment.

/home/xymon/server/etc/xymonserver.cfg
add this as one long line:

Take them out of the graphs.cfg file. I don't know if it's
strictly necessary to restart Xymon, but I did, and all the
graphs now come up with those colors. Not sure how to make it
work with individual graphs.

I edited one section to see what would happen. It threw an

Here's the section of my graphs.cfg that I edited. Anyone
know what the correct formatting is so I can stylize my graphs?

Something similar to Grafana would be awesome! It provides a
very rich set of graphing options. (see image below) No
idea if RRDs can be used though.

Can anyone advise on how to theme the graphs a bit? After
20 years of the light gray rectangles I'd like them to look
a little more modern.
