Bar gauge panel
{{< docs-imagebox img="/img/docs/v66/bar_gauge_cover.png" max-width="1025px" caption="Stat panel" >}}
This panel can show one or more bar gauges depending on how many series, rows or columns your query returns. The thresholds control the bar & value color.
Display options
- Show
Calculation- Show a calculated value like min or max based on all rows.All values- Show a separate stat for every row.
- Calc
- Specify calculation / reducer function. Since this panel is designed to only show a single value Grafana needs to know how to reduce a fields many values to a single value.
- Orientation
Horizontal- The bar will stretch horizontally from left to right.Vertical- The bar will stretch vertically from top to bottom.
- Mode
Gradient- The threshold levels define a gradient.Retro LCD- The gauge is split up in small cells that are lit or unlit.Basic- Single color based on the matching threshold.
Retro LCD example:

Field
Title- When multiple stats are shown this field controls the title in each stat. By default this is the series name and field name. You can use expressions like${__series.name}or${__field.name}to use only series name or field name in title or${__cell_2}to refer to other fields (2 being field/column with index 2).Min- The minimum value, leave blank for auto calculation based on all series & fields. Used by Graph to set y-axis min.Max- The maximum value, leave blank for auto calculation based on all series & fields. Used by Graph to set y-axis max.Decimals- Number of decimals to render value with. Leave empty for Grafana to automatically figure out the best number of decimals to use.
Thresholds
Define thresholds that will set the color of either the value or the background depending on your Color display option. The
thresholds are automatically sorted from lowest value to highest. The Base value represents minus infinity.
Value mappings
Map a number or a range of numbers to a text value.
