CanvasDataAction Class

CanvasDataAction is a subclass of the AbstractDataAction base class. You can extend this concrete class to provide the functionality you require.

CanvasDataAction

Use the CanvasDataAction class to navigate from a data point in a visualization to a different canvas. The canvas you're navigating to can be in the same workbook or a different one. All the active filters for the source visualization are passed to the target canvas along with new filters that describe the Qualified Data Reference of the data point itself. If your data action needs to navigate to a different canvas then this is the class your data action should extend.
