Description

2D Cube:  This type of chart is very similar to a bar chart, but instead of a bar a cube is displayed.  This chart is available from the toolbar or from the Options / General under Gallery type.  You can convert this type of chart to a conic or cylindrical chart.

3D Cube:  same as 2D but in 3D mode.  Changing from 2D to 3D can be done from the toolbar or from the Options / 3D View dialog boxes.  Please refer to bar charts for the different variations supported in Cube charts.
