[Xymon] changing graph canvas color

Thu Apr 28 21:42:30 CEST 2011

Round about line 1038 in  xymon-4.3.2/web/showgraph.c

If you just want to make the graph paper color non-white, you should only
need to add something like:

        rrdargs[argi++]  = "-c";
        rrdargs[argi++]  = "BACK#e9e9e9";

to get a light shade of grey.  If you want it configurable, there's several
places in that same file where bits need adding to be able to get options
from the graphs.cfg.
