I have created the following graph in Cacti: http://i43.tinypic.com/34y2nfo.png
I have created an aggregate of twenty graphs, this is great, it's stacked them on top of each other showing the total value with each contributing graph entry below.
All I want at the very bottom of the graph is a line with totals of the current, average and max values; but I'm pulling my hair out trying to make it happen? How can I do this?
