## Specifications

### Aggregation

Big Number [aggregates the selected metric without specifying dimensions](/data-exploration/chart/chart-common.md#dimension-metric) and displays it as a single value.

| Item             | Role   | Notes                                            |
| ---------------- | ------ | ------------------------------------------------ |
| Metric           | Metric | Displays the aggregated result as a single value |
| Secondary metric | Metric | Used as the maximum value for gauge              |

#### Example Configurations

* Show "Total sales overall" as text
  * Metric: Sum of sales
* Show "Achievement rate" as a gauge
  * Metric: Sum of actuals
  * Secondary metric: Sum of targets

### Gauge

* The gauge achievement rate is calculated as "Metric ÷ Secondary metric × 100"
* Secondary metric is required and must be numeric

## Tips

### Conditional styles

By configuring "Conditional styles" in "Advanced", you can change the font color based on the metric value. For example, you can color the value as danger when it is 80 or less, and success when it is 100 or more.
