Custom Chart Support for Cross-Visual Links and Filters

The zd-chart CLI supports the ability to publish and subscribe to cross-visual links. To implement publish/subscribe cross-visual filtering for custom charts, use the CLI to edit your charts and enable the controls for publish and subscribe. See Step 4. Enable Cross-Visual Filtering.

Publish should only be enabled if the custom chart uses the radial menu and filtering.

Cross-source links and same-source links are automatically populated and supported on the Cross-Visual Filtering tab of the Dashboard Interactions dialog for custom charts when they are added to a dashboard, in the following circumstances.

• When a custom chart has the Filter option in its radial menu, same-source links appear in the Published filters and Subscribed filters sections of the tab.

• When a custom chart does not have the Filter option in its radial menu, same-source links appear in the Subscribed filters section of the tab, but no Published filters section is shown.

• When two custom charts using different data sources are added to the dashboard and a cross-source link is added between their data sources, the cross-source link appears in the Published filters section for the chart that can publish the link (the chart using the first data source in the cross-source link) only. However, the cross-source link appears in the Subscribed filters section for both charts.

• Cross-visual filters are automatically applied to custom charts when they are added to a dashboard, in the following circumstances.

  • When two custom charts using the same data source are added to the dashboard, a cross-visual filter specified for the same-source link field on one custom chart is automatically applied to the other custom chart.

  • When two custom charts using different data sources are added to the dashboard and a cross-source link is added between their data sources, a cross-visual filter specified for the cross-source link field on one custom chart is automatically applied to the other custom chart.
