Drill-Down

  • 2 minutes to read

The built-in drill-down capability allows end-users to change the detail level of data displayed in dashboard items on the fly. To learn more about drill-down concepts common to all dashboard items, see the Drill-Down topic.

The Pie dashboard item supports drill-down on argument or series values.

Drill-Down on Arguments

When drill-down on arguments is enabled, an end-user can click a pie segment to view a detail diagram for the corresponding argument value.

Note

When Filtering by Arguments is enabled, an end-user can view the details by double-clicking a pie segment.

Anim_Pies_DrillDownOnArguments

Drill-down on arguments requires that the Arguments section contains several data items, from the least detailed to the most detailed item.

Pies_Interactivity_DrillDown_Arguments_DataItems

Note

In OLAP mode, you can perform drill-down for either a hierarchy data item or several dimension attributes. To learn more about OLAP mode, see Bind Dashboard Items to Data in OLAP Mode.

To enable drill-down on arguments, click the Drill Down button in the Data Ribbon tab (or the Chart_Interactivity_DrillDown_Toolbar button if you are using the toolbar menu)…

Chart_Interactivity_DrillDown_Ribbon

…and the Arguments button (or the Pies_Interactivity_MasterFilter_Arguments_Toolbar button if you are using the toolbar menu).

Drill-Down on Series

When drill-down on series is enabled, an end-user can click a pie chart to view a detail diagram for the corresponding series value.

Note

When Filtering by Series is enabled, an end-user can view the details by double-clicking a pie chart.

Anim_Pies_DrillDownOnSeries

Drill-down on series requires that the Series section contains several data items, from the least detailed to the most detailed item.

Pies_Interactivity_DrillDown_Series_DataItems

Note

In OLAP mode, you can perform drill-down for either a hierarchy data item or several dimension attributes.

To enable drill-down on series, click the Drill Down button in the Data Ribbon tab (or the Chart_Interactivity_DrillDown_Toolbar button if you are using the toolbar menu)…

Chart_Interactivity_DrillDown_Ribbon

…and the Series button (or the Pies_Interactivity_MasterFilter_Series_Toolbar button if you are using the toolbar menu).

Drill-Up

To return to the previous detail level (drill-up), use the Drill Up (DrillDown_DrillUpArrow) button in the caption of the Pie dashboard item, or the Drill Up command in the context menu.

Enable Drill-Down in Code

Use the ChartDashboardItemBase.InteractivityOptions property to access interactivity settings. This property returns the ChartInteractivityOptions object.

To enable drill-down, set the DashboardItemInteractivityOptions.IsDrillDownEnabled property to true. Use the ChartInteractivityOptions.TargetDimensions property to specify whether to drill down on arguments or series.
