China Map¶
Used to display the distribution of a certain Metrics data across different provinces.
Use Cases¶
- View data containing geographical location information;
- View dispersed data, such as population density;
- Compare data sizes through color intensity.
Chart Query¶
Prerequisites: The data set queried for Metrics must contain a tag representing province, and the query conditions must include grouping by province; otherwise, the chart cannot be successfully added.
Chart queries support simple queries, expression queries, PromQL queries, and data source queries; you can add multiple queries, but the by (grouping) Tag must be consistent.
For more detailed instructions, refer to Chart Query.
Chart queries match regions via provinces and colors via Metrics values:
| Option | Description |
|---|---|
| Province Tag | Select the tag representing the province. This tag must be a grouped tag in the query. The tag name for the province tag does not have to be province as long as its values represent provincial administrative regions. |
| Metrics | When multiple Metrics queries are added, you can set the primary displayed Metrics. The "main display Metrics" determines the gradient color of the color blocks. |
