I was wondering: Wouldn’t it be more significant to show the custom variable values rather than the names of the variable in the diagrams?
For example in your demo installation you track the variable “forum status”, which has the values either “LoggedIn user” or “Anonymous”.
At the moment the graph shows: 100% forum status, which is not very meaningful.
What I would like to see there is: 70% Anonymous, 30% LoggedIn user, which is the information you collected and you want to visualize.
Do I have a point here?
