[Xymon] changing graph canvas color

Thu Apr 28 22:00:49 CEST 2011

I'm generating some graphs by execing rrdtool from php:

   rrdtool graph --color BACK#xxxxx ... ... ...

and it sets the paper color all the way across the graph image.  I think
maybe CANVAS would set the paper color for the gridded area containing the
graph lines, with SHADEA for the top/left border and SHADEB for the
bottom/right border where the legend and labels are.  Etc for the other
options.
