I'm using the 3D Stacked Column Double-Y-axis Line Combo Chart (StackedColumn3DLineDY.swf). whew!
1) Is there a 2D equivalent of this graph?
2) Is there any way to adjust the depth and angle of the 3D columns?
3) I noticed that on the 2D Stacked Column Chart you can change the gradient color for the columns by simply adding color='ffffff,ff0000' to the dataset element. On this 3D graph, however, you can either have the 3D lighting effects turned on or off. If they're turned on, the color you specify fades to a darker shade. If they're turned off, there is no gradient at all, and adding the color='ffffff,ff0000' bit doesn't seem to work for me.
I also noticed that the plotGradientColor attribute was not available in the data plot cosmetics for this graph, why would it be available for a 2d graph and not a 3d one?
