In a 3D Bar chart, each data point is displayed as a single bar drawn from the Z-value to the origin. Spacing between adjacent bars is honored when using either grid or irregular grid data layout. You can customize the origin, spacing, and colors for the 3D Bar charts.
Use the axis Origin property to set the origin of the Z-axis. It is only used with Bar charts. Origin is located in the Bar node of the Chart3DGroup Collection Editor.
Use the bar RowWidth and ColumnWidth properties to set the space used by each bar. The value represents the percentage of available space, with valid values between 0 and 100. When 100, the bars touch one another. These properties are located in the Bar node of Chart3DGroup Collection Editor.
When a Bar chart is shaded but not zoned, bars drawn above the Z-origin use the surface top color and bars drawn below the Z-origin use the surface bottom color. The color of one bar or entire rows and columns of bars can be arbitrarily set. Create a 4D chart to define colors that appear in the Legend; see Displaying 4D Data for more information.
