Coordinate-Based Three-Dimensional Charts
When working with coordinate-based chart types (Column, Bar, Area, Point, Line and Range), three-dimensional effects display the chart with a third axis, known as the "z-axis". The introduction of this third axis allows you to apply a variety of visual enhancements to your chart.
Changing the White Space in a 3D Chart
When you display a chart area in three-dimensional mode, each series is shown in a separate row along the z-axis of the chart. To change the amount of space between each series, modify the chart's point gap depth by changing the Point Gap Depth property in the 3D Effects dialog box. For more information, see Chart Area Properties Dialog Box, 3D Options.
Changing the Projection of a 3D Chart
There are two types of 3D projections: oblique and perspective. An oblique projection to the chart adds a depth dimension to a two-dimensional chart. The z-axis is drawn at equal angles from the horizontal and vertical axes, which remain perpendicular to each other just as in a two-dimensional chart.
Perspective projection transforms the chart by estimating a view plane and re-drawing the chart as if it were being viewed from that point. The Rotation value shifts the view vertically from "ground level" at 0 to overhead at 90. The Inclination value shifts the viewing angle to the left or right. A value of 0 is equivalent to a two-dimensional view of the chart. The Perspective value defines the percentage of distortion that will be used when displaying the projection. This type of projection maintains the proportions of your chart, but the chart's appearance becomes distorted, so it is most effective to use a lower degree of perspective.

The oblique and perspective projections are separate types of projections, so they cannot be used together on the same chart.

Clustering Data
In 2D charts, multiple series of data appear side-by-side. Clustering shows individual series in separate rows on a 3D chart. For example, if you have a chart that contains three series of data points, clustering will display each of the three series on a separate row along the z-axis. By default, all chart types shown in 3D are clustered.
Clustering can be disabled for bar and column charts. When clustering is disabled, multiple bar and column series are displayed side-by-side in one row.
