Bar gauge

Bar gauges simplify your data by reducing every field to a single value. You choose how Grafana calculates the reduction.

This panel can show one or more bar gauges depending on how many series, rows, or columns your query returns.

Give it a try using Grafana Play

With Grafana Play, you can explore and see how it works, learning from practical examples to accelerate your development. This feature can be seen on Bar Gauge.
