Top customer by sale is Edbraxton if you are considering City ?
You can achieve this by filtering Customer name like this
And then inserting the same to the Tooltip
Here you go
Sorry I don't understand the logic of not checking any customer , better remove that field if you don't want customers.
Thanks for your response.
Allow me to explain you the scnerio.I want to see the city names corresponding to the customer names selected in the filter.Alongwith this,I want to see the top customer by sales per city on tooltip when hovering on the city in map(even when that top customer has been unchecked from the customer name filter).Hope this clears the scnerio.
