Nyquist
Use a Nyquist () plot to plot a Nyquist plot that shows the magnitude and phase of a frequency response. The plot shows the magnitude as the distance from the origin and the phase as the angle using a curve with the frequency as the parameter. Typical data to use for a Nyquist plot includes complex-valued impedance data from a frequency domain study. Add a Color Expression subnode as needed. Right-click a 1D Plot Group or Polar Plot Group to add this plot type.
Except where noted below, see Global for all of the settings. For Global Plots, the Expressions section is called y-Axis Data (or r-Axis Data for polar plots), but the instructions are the same.
Under Coloring and Style, select the Show unit circle check box to include a unit circle in the Nyquist plot.
