Change/Hide Visualization's label in DirectQuery mode

[AverageAsker]

I created a Pie Chart

The chart shows the label

NumberOfUsers by ProviderID

I am not satisfied with that label, how to change or hide it? I tried to rename the columns (pretty nasty way to change a label) but that didn't work - I got an error saying

This query contains transformations that cannot be used for a live connection

I a using DirectConnection and not using it is not an option. How to change or, at worst, hide the label in my case?

Figured this out - I had DirectQuery incompatibility in another dataset but got confused because error is seem to be disconnected from the source of the error in that regard that to see what/where actually was wrong I need to do number of additional steps.
