# Smith Chart Control

toolslib\toolbox\smith.fp

This instrument driver contains functions for creating a Smith Chart, a standard tool for visualizing transmission-line impedance characteristics. The chart plots normalized resistance and reactance in the reflection coefficient plane, using a standard LabWindows/CVI graph control.

You must create a Smith Chart by converting an existing graph control using SMITH_ConvertFromGraph. The Smith Chart inherits the size and position information from the graph control. When you finish using the chart, you must make a corresponding call to SMITH_DiscardChart.

| Note Refer to the function panels for function and parameter help for this control.
