XYZ point series.

Unit
TeePoin3
Description
To see a visual representation of this Series type, go to the TeeChart User Guide.
This Series is very similar to a TPointSeries, adding Z values for each point:
Series1.AddXYZ( 123, 456, 789 , 'Hello', clRed );
Point3D series does not impose any limit on the X,Y,Z coordinates or number of points.
Think as it is the same as a normal Point Series, with each point located inside the chart axes in a different XYZ position.
Points can optionally be displayed with lines that link them in the same order they were added to the series.
