This property returns the depth (or "drilled level") in the drill down hierarchy of the currently displayed child chart. Each time a user drills down, depth (their distance from the topmost chart) increases by one level. Calling the DrillBack() method or using the drill back button (see the ShowButton property), both reduce the depth by one level.
Depth is read-only. It cannot be directly modified to skip several levels in the drill down hierarchy. It is possible to have multiple Infragistics.UltraChart.Resources.DrillElement objects refer to equivalent child charts (identical Infragistics.UltraChart.Shared.Styles.ChartTypes and DataSources), even at different depths in the drill down hierarchy, thereby simulating the appearance of diving several levels at once.
