Enables drill down functionality in UltraChart. Before drill down can be fully realized, the DrillElement property must be initialized with an array of DrillElements that describe the drill down hierarchy.
For all WebCharts and WinCharts with custom Drill Down (IDrillDown) implemented, this property will have no effect. To disable Drill Down in a custom IDrillDown implementation, avoid calling your custom Drill method in the ChartDataClicked event handler.
