Gauge while moving over the graph

I have a graph with the photovoltaic yield when the arrow moves over the graph it sows the value. This built-in feature is very nice.

I would to show more. I’d like to move over and show a gauge from 0 to 100 upon the battery capacity at that time (value is in the field battery_capacity in the table row for the corresponding time).

The gauge might be in
. the tooltip
. the same panel

  • another panel in the same dashboard.

How can I do that?
