How to get stacked bar chart to show tooltip of current section on hover?

  • What Grafana version and what operating system are you using?

Grafana v8.3.4 (a551d74b11)

  • What are you trying to achieve?

I want to view the tooltip for a section of the bar chart

  • How are you trying to achieve it?

Hovering over the bar chart

  • What happened?

I am viewing a tool tip for another point at the same height (presumably this has a value of 0 so is occupying the same part of the bar chart).

As you can see in this screenshot, I want to see the tooltip/label for the yellow section of the bar chat. However, when I hover over, it shows me the tooltip for the blue label, which presumably is zero so appears at the same position.

How can I show the label of the part of the graph under the mouse, not a nearby point?

  • What did you expect to happen?

I would see the tool tip for the relevant section

  • Can you copy/paste the configuration(s) that you are having problems with?
