Documentation Grafana documentation Panels Visualizations Bar gauge panel

Bar gauge panel

The bar gauge simplifies 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.

Data and field options

Bar gauge visualizations allow you to apply:

• Data transformations
• Field options and overrides
• Thresholds

Display options

Use the following options to refine your visualization:

• Show - Choose how Grafana displays your data.
  • Calculate - Show a calculated value based on all rows. For a list of available calculations, refer to List of calculations.
  • All values - Show a separate stat for every row. If you select this option, then you can also select a Limit, or the maximum number of rows to display.
• Value - Select a reducer function that Grafana will use to reduce many fields to a single value. Click the Value list to see functions and brief descriptions.
