Which version gives a clear affordance on what happens when clicked?

I'm designing a drill-down chart that allows users to analyze meter readings at various locations in a factory. They are able to isolate a single location and see trends of the readings over time. The screens below show hover and clicked states where users can focus on one location by clicking on it. the reset to default button below will reset both charts to their previous state, showing all the locations.

my question is what is the most appropriate word on the hover state? currently its "click to view drill down", other options i'm considering are "click to analyze" or "click to inspect"

I believe based on that the reset below button would need to be aligned as well.
