# 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.

Bar gauge visualizations allow you to apply:
|
||
|
|

||
|
|
- Field settings
|
||
|
|
- Field overrides
|
||
|
|

## 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.
|
||
|
|
- **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.
|
||
|
|
- **Orientation -** Choose a stacking direction.
|
||
|
|
- **Auto -** Grafana selects what it thinks is the best orientation.
|
||
|
|
- **Horizontal -** Bars stretch horizontally, left to right.
|
||
|
|
- **Vertical -** Bars stretch vertically, top to bottom.
|
||
|
|
- **Display mode -** Choose a display mode.
|
||
|
|
- **Gradient -** Threshold levels define a gradient.
|
||
|
|
- **Retro LCD -** The gauge is split into small cells that are lit or unlit.
|
||
|
|
- **Basic -** Single color based on the matching threshold.
|
||
|
|
- **Show unfilled area -** Select this if you want to render the unfilled region of the bars as dark gray. Not applicable to Retro LCD display mode.
