ItemVisualInteractivityEventArgs Interface

Provides information for the ItemVisualInteractivity event.

Declaration

export interface ItemVisualInteractivityEventArgs extends DashboardItemBaseEventArgs

Remarks

Use the onItemVisualInteractivity handler to raise the ItemVisualInteractivity event.

The ItemVisualInteractivity event allows you to provide custom visual interactivity for data-bound dashboard items that support element selection and highlighting. This event is raised for dashboard items with disabled master filtering. Visual interactivity is enabled for master filter items by default. The Web Dashboard also fires this event when master filtering is applied to the current dashboard item or drill-down is performed in this dashboard item.

After the selection is changed, the ItemSelectionChanged event is raised. You can use the onItemSelectionChanged handler to raise this event.

The following table lists possible target axes for each dashboard item and supported interactivity capabilities.

Dashboard Item	Target Axes	Selection	Highlighting
GridDashboardItem	DefaultAxis	yes	no
ChartDashboardItem	ChartArgumentAxis	yes	yes
ChartDashboardItem	ChartSeriesAxis	yes	yes
ScatterChartDashboardItem	ChartArgumentAxis	yes	yes
PieDashboardItem	ChartArgumentAxis	yes	yes
PieDashboardItem	ChartSeriesAxis	yes	yes
CardDashboardItem	DefaultAxis	yes	yes
GaugeDashboardItem	DefaultAxis	yes	yes
MapDashboardItem	DefaultAxis	yes	yes
TreemapDashboardItem	DefaultAxis	yes	yes

Note

The Grid dashboard item does not support custom interactivity when Cell Merging is enabled.
