I have a set of graphs which display usage data for a site.  This value is displayed for a period of days on a line graph.

 

One of these sites is a dummy which contains a value (an average but not related to the other sites)

 

What I want to do is to display this average on the same graph as each other site.  there are 44 other sites and I want to have 44 graphs.

 

My report is grouped on the siteid but as you can imagine, i just get 45 graphs.

 

How can I do this?

 

Any suggestions will be gratefully recieved - thanks!
