Chart linkage allows you to use a chart as a filter. By clicking a data item in the chart, the associated charts will filter and display the data of the selected item. This article introduces how to use the chart linkage feature.

The chart linkage feature enables users to quickly find data in other charts corresponding to a specific factor.
When linkage effects have been applied on the dashboard page, you can use the "Clear all linkages" option in the upper right corner of the page to clear all active linkage states in the current sheet with one click, making it easy to quickly return to the unlinked viewing state.
Example usage scenario:

• Real-time linkage between summary and detail tables: In the regional sales summary table, you can view the overall sales performance for each region, and link to the detail table to view the sales performance of Sales representatives in the region.
  

1. Go to the dashboard editing page, click the options in the upper right corner of the chart to be configured for linkage, and select "Linkage".
   
2. Select the charts to be linked with the current chart, click "Confirm", and chart linkage will be enabled.

• To link charts that use the same dataset as the current chart, simply select the chart name. In the example below, "Chart linkage detail table" is selected.
  
• To link charts that use a different dataset from the current chart, you need to associate fields.
  

3. Click any data item to view the chart linkage effect.
   

• To link charts that use the same dataset as the current chart, simply click "Confirm".
  
• To link charts that use a different dataset from the current chart, you need to configure the mapping between fields.
  
  • At least one field must be associated. Once this condition is met, the field configuration box will change from red to green.
  • Caution: When the field value is null (empty), linkage does not take effect.
  • If there are drill-down fields under the current primary field (see Drill Up and Drill Down), drill-down fields also support linkage configuration.

Single data point linkage #

• Click the dimension field "2013-09-09" in the source chart, and the linked chart will display the corresponding data for "2013-09-09".
  
• Click the value "10,734.81" in the metric field "price" in the source chart. All dimension field values in that row will be passed to the linked chart, so the linked chart will display the corresponding data for "Fujian-Fuzhou".
  

Multiple data point linkage #

If multiple data points are selected in the linked chart, multiple data point linkage will be achieved.

When any linkage effect exists on the current dashboard sheet page, a "Clear all linkages" button will appear in the upper right corner. You can click the button to clear the linkage effect.

To cancel only the current linkage result, you can click again on the field or data point that previously triggered the linkage, or click on a blank area of the chart.
If multiple linkage results have already been generated on the current page, you can click the "Clear all linkages" button in the upper right corner of the page to clear all linkage results on the current page at once.

In dashboard edit mode, clicking the chart's cancel linkage button will clear the linkage configuration for that chart.
