Create Pie Chart

[kennedto]

I have a query that returns:

YEAR  ASSETSRC  EventCount
2016    Austin                 4
2016    IRLP                    1

Other ASSETSRC values are possible.
I want to create a pie chart out of this.
I tried several combinations of adding ASSETSRC and Event Count to the default measure and series, but I always get No Data Available returned.

Can someone  give me a hint  as to what I am doing wrong?

Is your pie chart associated with your query?
