Hello,

You can't change the background of a graph with cacti.
Cacti use an image file generated by RRDtool.
The only thing that you can change, is the label at the bottom on the graph.
But, this use an RRD function to add a single text.

I think the only way to do this is to include an custom image merge function with GD in cacti php file. Warning, cacti performance decrease on consultation if you do that...

Yep, image merge in PHP is costly. Maybe, it's easy to change code in RRDTool ? - it's GNU also.. Or, just get use to current background color (much easier )

Worked for me with NxTrek's suggestion

"-c CANVAS#000000 -c FONT#FFFFFF -c BACK#000000 --title=\"" . $graph["title_cache"] . "\"" . RRD_NL .

in rrdtool.php

This worked for me.

8.7e
rrd.php file under lib.

- user specific setting

Did this feature make the cut for 0.8.8b?
