Shows each available chart type and a variety of 3D chart options.

The sample creates any of the 3D chart types, including surface, bar or
scatter charts, and demonstrates a variety effects techniques.

Controls on the sample form allow various rotation and elevation
settings and selection of value or value label annotation methods.

ChartLabels are attached to mouse selected data points by tracking and
mapping the mouse coordinates.  As points are selected, the OnPaint
event of the chart is used to draw on the chart to indicate the selected
point.  The Z value for a selected point may be change through a popup
dialog.  Alpha blending is used to show some effects more clearly.

Additionally, the sample demonstrates the use of hole values in a 3D
chart, as well as individual bar coloring.
