Important: This documentation is about an older version. It's relevant only to the release noted, many of the features and functions have been updated or replaced. Please view the current version.
Gauge
Gauges are single-value visualizations that can repeat a gauge for every series, column or row.
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 Grafana Gauge Visualization.
Panel options
In the Panel options section of the panel editor pane, you set basic options like the panel title and description. You can also configure repeating panels in this section. To learn more, refer to Configure panel options.
Value options
Use the following options to refine how your visualization displays the value:
Show
Choose how Grafana displays your data.
Calculate
Show a calculated value based on all rows.
- Calculation - 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.
- Fields - Select the fields display in the panel.
All values
Show a separate stat for every row. If you select this option, then you can also limit the number of rows to display.
- Limit - The maximum number of rows to display. Default is 5,000.
- Fields - Select the fields display in the panel.
Gauge
Adjust how the gauge is displayed.
Orientation
Choose a stacking direction.
- Auto - Gauges display in rows and columns.
- Horizontal - Gauges display top to bottom.
- Vertical - Gauges display left to right.
Show threshold labels
Controls if threshold values are shown.
Show threshold markers
Controls if a threshold band is shown outside the inner gauge value band.
Gauge size
Choose a gauge size mode.
- Auto - Grafana determines the best gauge size.
- Manual - Manually configure the gauge size.
Min width
Set the minimum width of vertically-oriented gauges.
If you set a minimum width, the x-axis scrollbar is automatically displayed when there’s a large amount of data.
Note
This option only applies when gauge size is set to manual.
Min height
Set the minimum height of horizontally-oriented gauges.
If you set a minimum height, the y-axis scrollbar is automatically displayed when there’s a large amount of data.
Note
This option only applies when gauge size is set to manual.
Neutral
Set the starting value from which every gauge will be filled.
Text size
Adjust the sizes of the gauge text.
- Title - Enter a numeric value for the gauge title size.
- Value - Enter a numeric value for the gauge value size.
Standard options
Standard options in the panel editor pane let you change how field data is displayed in your visualizations. When you set a standard option, the change is applied to all fields or series. For more granular control over the display of fields, refer to Configure overrides.
You can customize the following standard options:
- Unit - Choose which unit a field should use.
- Min/Max - Set the minimum and maximum values used in percentage threshold calculations or leave these field empty for them to be calculated automatically.
- Field min/max - Enable Field min/max to have Grafana calculate the min or max of each field individually, based on the minimum or maximum value of the field.
- Decimals - Specify the number of decimals Grafana includes in the rendered value.
- Display name - Set the display title of all fields. You can use variables in the field title.
- Color scheme - Set single or multiple colors for your entire visualization.
- No value - Enter what Grafana should display if the field value is empty or null. The default value is a hyphen (-).
To learn more, refer to Configure standard options.
Data links
Data links allow you to link to other panels, dashboards, and external resources while maintaining the context of the source panel. You can create links that include the series name or even the value under the cursor.
For each data link, set the following options:
- Title
- URL
- Open in new tab
To learn more, refer to Configure data links.
Value mappings
Value mapping is a technique you can use to change how data appears in a visualization.
For each value mapping, set the following options:
- Condition - Choose what’s mapped to the display text and (optionally) color:
- Value - Specific values
- Range - Numerical ranges
- Regex - Regular expressions
- Special - Special values like
Null
,NaN
(not a number), or boolean values liketrue
andfalse
- Display text
- Color (Optional)
- Icon (Canvas only)
To learn more, refer to Configure value mappings.
Thresholds
A threshold is a value or limit you set for a metric that’s reflected visually when it’s met or exceeded. Thresholds are one way you can conditionally style and color your visualizations based on query results.
Set the following options:
- Value - Set the value for each threshold.
- Thresholds mode - Choose from:
- Absolute
- Percentage
To learn more, refer to Configure thresholds.
Field overrides
Overrides allow you to customize visualization settings for specific fields or series. When you add an override rule, it targets a particular set of fields and lets you define multiple options for how that field is displayed.
Choose from one the following override options:
- Fields with name - Select a field from the list of all available fields.
- Fields with name matching regex - Specify fields to override with a regular expression.
- Fields with type - Select fields by type, such as string, numeric, or time.
- Fields returned by query - Select all fields returned by a specific query, such as A, B, or C.
- Fields with values - Select all fields returned by your defined reducer condition, such as Min, Max, Count, Total.
To learn more, refer to Configure field overrides.
