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.

graph theme

values can be found at https://oss.oetiker.ch/rrdtool/doc/rrdgraph.en.html

RRDGRAPHOPTS="-E -R light --border 0 --dynamic-labels -a PNG --grid-dash 1:0 -n LEGEND:8:Roboto -n TITLE:9:Roboto -n AXIS:7:Roboto -n UNIT:7:Roboto -n WATERMARK:.1:Roboto -c BACK#262626 -c CANVAS#000000 -c SHADEA#000000 -c SHADEB#000000 -c GRID#00000000 -c MGRID#DDDDDD11 -c FONT#DDDDDD -c AXIS#262626 -c FRAME#000000 -c ARROW#262626"

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.

There may be a better place to put this, but it works for me.  In:

     /home/xymon/server/etc/xymonserver.cfg

add this as one long line:

RRDGRAPHOPTS="-c BACK#363636 -c CANVAS#000000 -c SHADEA#CFCFCF -c SHADEB#CFCFCF -c GRID#222222 -c MGRID#441E1E -c FONT#FFFFFF -c AXIS#696969 -c FRAME#000000 -c ARROW#FA0016"

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 tried adding the color lines into my graphs.cfg file as
specified in this how-to
https://oss.oetiker.ch/rrdtool/doc/rrdgraph.en.html

I edited one section to see what would happen.  It threw an error
that said _*invalid color def format*_

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.
