Admittedly I have not done a single bit of research on this as I am on my way out the door and just got this request... but thought maybe someone would have a quick solution.
I have a dashboard view that shows charts of internet usage on three different interfaces. Each one has a specific bandwidth set. I want to add one more chart to the page that consolidates all three into one chart showing the percent utilization of the total bandwidth combined. Am I going to be able to do that? If so, how. 
Sorry for taking the lazy way out on this one... just bad timing.
TIA for any help...
