GPRINT Average: is it accessable as a variable??

[chkaotic]

Basically here is what I am looking at doing:

I have an ICMP latency graph that, of course, has one data input. I have actually made 10 data input items, and limited them to 20 msec chunks so that depending on the latency, the graph changes color.. simple enough..

What I am wanting to do is to make an HRULE to go straight through the graph and have it equal to the average latency of the graph's timeline (the same value you see if you look in the GPRINT legend for "Average"..

Is there a variable for this that I can plug into the HRULE value field? such as |average| or something? (its not |average| though, already tried that)

Any ideas?
