⛔ DEPRECATED. This project was moved to a new repository. Visit dashboard-extensions to find an updated version.
The current repository does not support the modular approach for HTML JS Dashboard and will not be updated in the future.
A custom FunnelD3 item renders a funnel chart using the D3Funnel JS library.
This dashboard item supports the following capabilities:
- Master-Filtering
- Drill-Down
- Exporting
- Appearance Customization
Note that the custom export functionality implemented in the Funnel D3 item is not supported for the Internet Explorer browser due to the problem with HTML canvas drawing. If you use IE 11 or earlier versions, the export buttons will be hidden. Refer to the following Microsoft issue to learn more: https://developer.microsoft.com/en-us/microsoft-edge/platform/issues/1015651/.
