1 test, 1 graph, multiple lines

Hi ! I'm new to this ML, and I'm almost a script dev (almost is the most accurate word in this mail). I created a script to monitor game servers activity. It reports the number of player on a server. The ouput is formated as it : &global_color $machine.$test <many words> &color server1 is OK|NOK Players: <INTEGER> I followed the ~(hobbit|xymon)/help/howtograph.html help file, and i get my graph when I monitor 1 game server. My script supports several game servers monitoring, but I can't find a way to have graph for all of them, like the http tests do (1 test, many URL tested, and one graph with all URL on it). Can someone help me ? Sorry for my poor english, I'm better in speaking my homeland language ;)
