Hi Ryan,
I am not sure whether you have tried this. As per my understanding you want to show sum and average values of all the agents in a chart or table without any dimensions? If right please try this
create variables like this
avg =Average([Sales revenue])/Count([State])
sum=sum([Sales revenue])
dimension Dummy=""
create chart with these 2 measures and dummy dimension. this is becz we need atleast one dimension for creating a chart
