Manhattan Bar 3D Series Type (with support for real Z axis) Decline reason: You can use the new RadChartView3D BarSeries3D. http://docs.telerik.com/devtools/wpf/controls/radchartview3d/series/barseries3d
I have no point in a "3D graph" if it doesn't let my put different columns in the Z axis. The current "3D" things are just thick-2D graphs that you can spin.
