I can't say I've ever tried that.  I would think you need to append to
rather than replace the graph options though, so wouldn't it be ..

  $conf['graph_opt'] .= " --watermark 'Test'"

(note the ".=" rather than just "=" and the space added before --watermark )

I don't have my Nagios system to hand at the moment so can't take a
look myself.  Remind me on Monday if you're still stuck and I'll have
a play with that myself.

Another option is to create some graphs outside of PNP altogether (but
using the .rrd databases created by PNP).  See:

Again, I can dig out some examples for you if you remind me during the
week (or do a search - I'm sure we've covered this topic before either
here or on the PNP email list some time in the last few months).
