The Stat panel displays a single value with optional background coloring, sparklines, and percentage change indicators.

​
Overview

The Stat panel is ideal for displaying:
  • Current values of metrics
  • Statistical summaries (min, max, average)
  • Percentage changes over time
  • Key performance indicators (KPIs)
  • Status indicators with color coding

​
Panel Options

The Stat panel is defined in public/app/plugins/panel/stat/module.tsx:18: 
export const plugin = new PanelPlugin<Options>(StatPanel)
  .useFieldConfig()
  .setPanelOptions((builder) => {
    addStandardDataReduceOptions(builder);
    addOrientationOption(builder, mainCategory);
    commonOptionsBuilder.addTextSizeOptions(builder, { 
      withTitle: true, 
      withValue: true, 
      withPercentChange: true 
    });
    // ... additional options
  })
  .setNoPadding()
  .setPanelChangeHandler(statPanelChangedHandler);

​
Options Interface

From public/app/plugins/panel/stat/panelcfg.gen.ts:15: 
interface Options extends SingleStatBaseOptions {
  colorMode: BigValueColorMode;
  graphMode: BigValueGraphMode;
  justifyMode: BigValueJustifyMode;
  percentChangeColorMode: PercentChangeColorMode;
  showPercentChange: boolean;
  textMode: BigValueTextMode;
  wideLayout: boolean;
}

​
Default Options

From public/app/plugins/panel/stat/panelcfg.gen.ts:25: 
const defaultOptions: Partial<Options> = {
  colorMode: BigValueColorMode.Value,
  graphMode: BigValueGraphMode.Area,
  justifyMode: BigValueJustifyMode.Auto,
  percentChangeColorMode: PercentChangeColorMode.Standard,
  showPercentChange: false,
  textMode: BigValueTextMode.Auto,
  wideLayout: true,
};

​
Text Mode

Control what text is displayed (from public/app/plugins/panel/stat/module.tsx:28): 
enum BigValueTextMode {
  Auto = 'auto',             // Automatic based on space
  Value = 'value',           // Show only the value
  ValueAndName = 'value_and_name',  // Show value and series name
  Name = 'name',             // Show only the series name
  None = 'none'              // No text
}

​
Color Mode

Control how color is applied (from public/app/plugins/panel/stat/module.tsx:62): 
enum BigValueColorMode {
  None = 'none',                    // No coloring
  Value = 'value',                  // Color the value text
  Background = 'background',        // Gradient background
  BackgroundSolid = 'background_solid'  // Solid color background
}

​
Graph Mode

Display a sparkline graph (from public/app/plugins/panel/stat/module.tsx:82): 
enum BigValueGraphMode {
  None = 'none',  // No graph
  Area = 'area'   // Area sparkline
}

​
Justify Mode

Control text alignment (from public/app/plugins/panel/stat/module.tsx:95): 
enum BigValueJustifyMode {
  Auto = 'auto',     // Automatic based on layout
  Center = 'center'  // Always center
}

​
Wide Layout

When using textMode: 'value_and_name', the wide layout option controls whether the name and value are displayed side-by-side (wide) or stacked (from public/app/plugins/panel/stat/module.tsx:47): 
wideLayout: boolean  // Default: true

​
Percent Change

Display percentage change from previous value (from public/app/plugins/panel/stat/module.tsx:107): 
showPercentChange: boolean  // Default: false
Percent Change Color Mode (from public/app/plugins/panel/stat/module.tsx:114): 
enum PercentChangeColorMode {
  Standard = 'standard',    // Green for positive, red for negative
  Inverted = 'inverted',    // Red for positive, green for negative
  SameAsValue = 'same_as_value'  // Use same color as value
}
Percent change is only available when not displaying all values (reduceOptions.values: false).

​
Orientation

Control layout direction: 
enum VizOrientation {
  Auto = 'auto',         // Automatic based on panel size
  Horizontal = 'horizontal',
  Vertical = 'vertical'
}

​
Data Reduce Options

Control how multiple values are reduced to a single value: 
interface ReduceDataOptions {
  values: boolean;    // Show all values or reduce to one
  fields?: string;    // Field name pattern
  limit?: number;     // Max number of values to show
  calcs: string[];    // Reducer functions: 'last', 'mean', 'sum', etc.
}
Common reducers:
  • last - Last value (default)
  • first - First value
  • mean - Average
  • sum - Sum of all values
  • min - Minimum value
  • max - Maximum value
  • count - Number of values

​
Text Size Options

Control text sizing: 
interface TextSize {
  titleSize?: number;        // Title font size
  valueSize?: number;        // Value font size
  percentChangeSize?: number; // Percent change font size
}

Advanced Features

​
Custom Thresholds

Use thresholds to define color ranges based on values: 
{
  "thresholds": {
    "mode": "absolute",
    "steps": [
      { "value": 0, "color": "green" },
      { "value": 50, "color": "yellow" },
      { "value": 80, "color": "red" }
    ]
  }
}
Or use percentage mode: 
{
  "thresholds": {
    "mode": "percentage",
    "steps": [
      { "value": 0, "color": "green" },
      { "value": 50, "color": "yellow" },
      { "value": 80, "color": "red" }
    ]
  }
}

​
Value Mappings

Map specific values to custom text and colors: 
{
  "mappings": [
    {
      "type": "value",
      "value": "0",
      "text": "Down",
      "color": "red"
    },
    {
      "type": "value",
      "value": "1",
      "text": "Up",
      "color": "green"
    },
    {
      "type": "range",
      "from": 2,
      "to": 10,
      "text": "Multiple",
      "color": "blue"
    }
  ]
}
Add clickable links to stat values: 
{
  "links": [
    {
      "title": "View Details",
      "url": "/d/detailed-dashboard",
      "targetBlank": false
    }
  ]
}

Implementation Details

The Stat panel extends SingleStatBaseOptions which provides common functionality shared with the Gauge and Bar Gauge panels. Key files:
  • public/app/plugins/panel/stat/module.tsx - Plugin definition
  • public/app/plugins/panel/stat/StatPanel.tsx - Component implementation
  • public/app/plugins/panel/stat/panelcfg.gen.ts - Generated types
  • public/app/plugins/panel/stat/common.ts - Shared utilities
The Stat panel uses setNoPadding() to remove default panel padding for edge-to-edge display.

Gauge Panel

Display values with radial gauges

Graph Panel

Visualize time series data
