Documentation Grafana documentation Panels and visualizations Visualizations Stat

Stat

A stat visualization displays your data in single values of interest—such as the latest or current value of a series—with an optional graph sparkline. A graph sparkline, which is only available in stat visualizations, is a small time-series graph shown in the background of each value in the visualization.

For example, if you’re monitoring the utilization of various services, you can use a stat visualization to show their latest usage:

Use a stat visualization when you need to:

• Monitor key metrics at a glance, such as the latest health of your application, number of high priority bugs in your application, or total number of sales.
• Display aggregated data, such as the average response time of your services.
• Highlight values above your normal thresholds to quickly identify if any metrics are outside your expected range.

Give it a try using Grafana Play

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 Stat Visualizations in Grafana.

Configure a stat visualization

Once you’ve created a dashboard, the following video shows you how to configure a stat visualization:

Alternatively, refer to this blog post on how to easily retrieve values from a range in Grafana using a stat visualization.

Supported data formats

The stat visualization supports a variety of formats for displaying data. Supported formats include:

• Single values - The most common format and can be numerical, strings, or boolean values.
• Time-series data - Calculation types can be applied to your time-series data to display single values over a specified time range.

Examples

The following tables are examples of the type of data you need for a stat visualization and how it should be formatted.

Single numerical values

The data is visualized as follows, with the last value displayed, along with a sparkline and percentage change:

Time-series data

The data is visualized as follows, with the mean value displayed for each room, along with the room name, sparkline, and unit of measurement:

By default, a stat displays one of the following:

• Just the value for a single series or field.
• Both the value and name for multiple series or fields.

You can use the Text mode to control how the text is displayed.

Automatic layout adjustment

The panel automatically adjusts the layout depending on available width and height in the dashboard. It automatically hides the graph (sparkline) if the panel becomes too small.

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 its values:

Show

Display a single value per column or series, or show values for each row.

Calculate

Display 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 visualization.

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 visualization.

Stat styles

Style your visualization.

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.

Text mode

You can use the Text mode option to control what text the visualization renders. If the value is not important, only the name and color is, then change the Text mode to Name. The value will still be used to determine color and is displayed in a tooltip.

• Auto - If the data contains multiple series or fields, show both name and value.
• Value - Show only value, never name. Name is displayed in the hover tooltip instead.
• Value and name - Always show value and name.
• Name - Show name instead of value. Value is displayed in the hover tooltip.
• None - Show nothing (empty). Name and value are displayed in the hover tooltip.

Wide layout

Set whether wide layout is enabled or not. Wide layout is enabled by default.

• On - Wide layout is enabled.
• Off - Wide layout is disabled.

Color mode

Select a color mode.

• None - No color applied to the value.
• Value - Applies color to the value and graph area.
• Background Gradient - Applies color to the value, graph area, and background, with a slight background gradient.
• Background Solid - Applies color to the value, graph area, and background, with a solid background color.

Graph mode

Select a graph and sparkline mode.

• None - Hides the graph and only shows the value.
• Area - Shows the area graph below the value. This requires that your query returns a time column.

Text alignment

Choose an alignment mode.

• Auto - If only a single value is shown (no repeat), then the value is centered. If multiple series or rows are shown, then the value is left-aligned.
• Center - Stat value is centered.

Show percent change

Set whether percent change is displayed or not. Disabled by default.

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 like true and false
• 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.
