Bar gauge

Bar gauges simplify your data by reducing every field to a single value. You choose how Grafana calculates the reduction. This visualization can show one or more bar gauges depending on how many series, rows, or columns your query returns.

The bar gauge visualization displays values as bars with various lengths or fills proportional to the values they represent. They differ from traditional bar charts in that they act as gauges displaying metrics between ranges. One example is a thermometer displaying body temperature in a bar filling up.

You can use a bar gauge visualization when you need to show:

Key performance indicators (KPIs)
System health
Savings goals
Attendance
Process completion rates

Configure a bar gauge visualization

The following video shows you how to create and configure a bar gauge visualization:

Supported data formats

To create a bar gauge visualization, you need a dataset querying at least one numeric field. Every numeric field in the dataset is displayed as a bar gauge. Text or time fields aren't required but if they're present, they're used for labeling.

Example 1

Label	Value1	Value2	Value3
Row1	5	3	2

The minimum and maximum range for the bar gauges is automatically pulled from the largest and smallest numeric values in the dataset. You can also manually define the minimum and maximum values as indicated in the Standard options section.

You can also define the minimum and maximum from the dataset provided.

Example 2

Label	Value	Max	Min
Row1	3	6	1

If you don’t want to show gauges for the min and max values, you can configure only one field to be displayed as described in the Value options section.

Even if the min and max aren’t displayed, the visualization still pulls the range from the data set.

Example 3

The bar gauge visualization also supports multiple records (rows) in the dataset.

Label	Value1	Value2	Value3
Row1	5	3	2
Row2	10	6	4
Row3	20	8	2

By default, the visualization is configured to calculate a single value per column or series and to display only the last set of data. However, it derives the minimum and maximum from the full dataset even if those values aren’t visible. In this example, that means only the last row of data is displayed in the gauges and the minimum and maximum values are defined as 2 and 20, pulled from the whole dataset.

If you want to show one gauge per cell you can change the Show setting from Calculate to All values and each bar is labeled by concatenating the text column with each value's column name.

For more information on these settings, refer to Value options.

Value options

Use the following options to refine how your visualization displays the value:

Option	Description
Show	Set how Grafana displays your data. Choose from: Calculate - Show a calculated value based on all rows. All values - Show a separate value for every row. If you select this option, then you can also limit the number of rows to display.
Calculation	If you chose Calculate as your Show option, select a reducer function that Grafana will use to reduce many fields to a single value. For a list of available calculations, refer to Calculation types.
Limit	If you chose All values as your Show option, enter the maximum number of rows to display. The default is 5,000.
Fields	Select the fields display in the panel.

Bar gauge options

Adjust how the gauge is displayed.

Option	Description
Orientation	Choose a stacking direction: Auto - Grafana determines the best orientation. Horizontal - Bars stretch horizontally, left to right. Vertical - Bars stretch vertically, bottom to top.
Display mode	Choose a display mode: Gradient - Threshold levels define a gradient. Retro LCD - The bar is split into sections that are lit or unlit. Basic - Single color based on the matching threshold.
Value display	Choose a value display mode: Value color - Value color is determined by value. Text color - Value color is default text color. Hidden - Values are hidden.
Name placement	Set the name placement mode when the bar gauge orientation is Auto or Horizontal. Choose from: Auto - Grafana determines the best placement. Top - Names are placed on top of each bar gauge. Left - Names are placed to the left of each bar gauge. Hidden - Names are hidden. When the bar gauge is in the vertical orientation, choose from Auto (names are always placed at the bottom of each bar) or Hidden.
Show unfilled area	Select if you want to render the unfilled region of the bars as dark gray. Not applicable to Retro LCD display mode.
Bar size	Choose a bar size mode: Auto - Grafana determines the best bar size. Manual - Manually configure the bar size.
Min width	Limit the minimum width of the bar column when the gauge is oriented vertically or is in Auto mode. Automatically shows the x-axis scroll bar when there's a large amount of data. This option only applies when the Bar size mode is set to Manual.
Min height	Limit the minimum height of the bar row when the bar gauge is oriented horizontally or is in Auto mode. Automatically shows the y-axis scroll bar when there's a large amount of data. This option only applies when the Bar size mode is set to Manual.
Max height	Limit the maximum height of the bar row when the bar gauge is oriented horizontally or is in Auto mode. Automatically shows the y-axis scroll bar when there's a large amount of data. This option only applies when the Bar size mode is set to Manual.
