hey gang,<br><br>I'm trying to create a graph that uses a datasource from a number of different rrd files to show total items in the queue.<br><br>I have the graph working, but I want to add a legend item that shows the total.<br>
<br>right now, the graph (a stacked graph) shows a different band for each server and the legend displays the text "<server name> <X> messages in the queue".<br><br>but how can i add up all the values so i can print "total <X> messages in the queue"?<br>
<br>i'm doing this on a php page if that helps/matters. I have a foreach loop that extracts the ds value for each server in a list.<br><br><br><br>(rrdtool = 1.3.8)<br><br>thanks!<br><br>thanks!<br><br>J<br>
