The 3D Scientific Graph uses ZData to identify data plotted against the z axis.
The Scientific Graph Object uses ZData to control bubble sizes for the Bubble plotting method. The object will evaluate the range of ZData and then proportionally size bubbles with respect to that range. See PlottingMethod, BubbleSize
The Polar/Smith Object uses ZData when SmithChart equals TRUE to identify an alternate list of R/X Rings to create Smith chart grid. Start with lowest non-zero value and increase R/X values. End the list with an R/X value of zero. Default R/X grid values are: 0.2 / 0.4 / 0.6 / 0.8 / 1.0 / 1.5 / 2.0 / 3.0 / 4.0 / 5.0 / 10.0 / 20.0 / 50.0 / 0.0
For the Scientific Graph, the format of the data is defined by the SubsetByPoint property.
For the 3D Scientific Graph, data is always structured Subset by Point, or in other words, for the case when SubsetByPoint is TRUE.
CommentsPeData.Z members of Pego.PeData, Pesgo.PeData, Pepso.PeData, Pe3do.PeData
If greater precision is needed with the 3D Scientific Graph, set UsingZDataII to TRUE and use ZDataII instead of this property.
When used with PEvget, the destination buffer must be large enough to hold all of information. For property arrays, calling PEvget with lpDest equal to NULL will return the number of bytes needed to hold the data.
See Also: ScaleForZData, XData, YData.
Refer to the example 400 for more information on the use of this property.
