If you really want to be able to add anything (such as notes on the graph itself, and so on) then use rrdgraph to generate an image, and then use the GD library (or similar) to load and modify this image before display.

Otherwise, as Darren mentions, there are the 'COMMENT' and 'GPRINT' directives to add text to the legend.

You can use GPRINT and COMMENT fields to place text into window beneath
the graph.  You can't point to a peak with them, but it's appropriate
for longer text bits.
