In the 2D bubble chart I see where you set x, y, and radius

ctrlUltraChart

ctrlUltraChart.BubbleChart.ColumnY = Y axis column

ctrlUltraChart.BubbleChart.ColumnZ = Radius column

But in the 3D bubble chart I don't see where to set the radius since ColumnZ no longer equals radius

Here is info on the bubble chart 3D showing it needs four columns

when I look in

ctrlUltraChart

I don't see anywhere to set the fourth(radius column)

any help would be much appreciated, thank you, Jamie
