Takes data for a Smith plot and normalizes it, meaning that the data is scaled relative to a known value.
You can wire either an array of points, where each point is a cluster of an r and an x value, or an array of complex data to this VI. The VI detects which data input you wire and uses that input. If you wire both inputs, the VI normalizes the array of points.

This VI normalizes the data with respect to a specified characteristic impedance, Zo, of the system. Then it returns the resulting data as an array of clusters of points, where each cluster contains an r and an x value. You can wire the normalized smith points output directly to the Smith Plot VI.
Refer to the Smith Multi Plot with Styles VI in the labview\examples\picture\demos.llb for an example of using the Normalize Smith Plot VI.
