Customize label when hovering above bar chart

[MikeOnzay]

When I hover over a bar on a chart that is showing the total for that category the hover label shows a date, time:count. e.g. 9/1/17, 12:00 AM: 128. The underlying map's popup does not have the time part checked.

Is it possible to customize this label? In this case all I want to show is the count.

Any updates for this enhancement? customizing hover text is an essential feature for my dashboard

UPDATE: This question is now an idea.
