I've been dicking about with GD::Graph for the past few days. I'm using two y-axis, in an area, line arrangement, and would like to add an "arbitrary" vertical line thru' the graph (something like mrtg does to indicate now() ).

I've rtfm, but cant see any obvious way to do this.

Rather than do some post processing on the image, is there a method to do this?
