Dynamic chart from URL variable
Hi I'm trying to populate a chart with dynamic data based on a URL variable i.e.
http://www.myDomain.com/sompage.php?treeId="here is my variable"
I'm not exactly sure how to do this I noticed that there is a method for this but I am not sure how to tie it all together if maybe you could give me some instructions or point me to a tutorial thanks
I do know that there is a drop down list for filtering which allows you to set some parameters to either Session Variable or URl parameter but how do you make it work??
