Perspective provides Excel charts with an effect of objects that are closer appearing larger and those that are farther away appearing smaller. In other words, perspective can add depth to a chart. This, of course, simulates the way you see things out in the world. Charts don't necessarily need this treatment, but it's available for you to use.

Here's how to adjust the perspective of a 3-D chart:

1. Create and select a 3-D chart, or open a workbook with a 3-D chart and select it.

2. Choose Chart, 3-D View.

3. Adjust the perspective setting.

4. Click OK to close the dialog box and to see the change in the chart.

The use of perspective can work against you. The use of perspective may make it seem that the data points are not equal in value, although in fact they're identical.
