control.nichols_plot(data, omega=None, *fmt, grid=None, title=None, ax=None, label=None, **kwargs)[source]

Nichols plot for a system.

Plots a Nichols plot for the system over a (optional) frequency range.

Parameters:

datalist of FrequencyResponseData or LTI: List of LTI systems or FrequencyResponseData objects. A single system or frequency response can also be passed.
omegaarray_like: Range of frequencies (list or bounds) in rad/sec.
*fmtmatplotlib.pyplot.plot format string, optional: Passed to matplotlib as the format string for all lines in the plot. The omega parameter must be present (use omega=None if needed).
gridboolean, optional: True if the plot should include a Nichols-chart grid. Default is True and can be set using config.defaults['nichols.grid'].
**kwargsmatplotlib.pyplot.plot keyword properties, optional: Additional keywords passed to matplotlib to specify line properties.

Returns:

cpltControlPlot object: Object containing the data that were plotted. See ControlPlot for more detailed information.
cplt.linesArray of matplotlib.lines.Line2D objects: Array containing information on each line in the plot. The shape of the array matches the subplots shape and the value of the array is a list of Line2D objects in that subplot.
cplt.axes2D ndarray of matplotlib.axes.Axes: Axes for each subplot.
cplt.figurematplotlib.figure.Figure: Figure containing the plot.
cplt.legend2D array of matplotlib.legend.Legend: Legend object(s) contained in the plot.

Other Parameters:

axmatplotlib.axes.Axes, optional: The matplotlib axes to draw the figure on. If not specified and the current figure has a single axes, that axes is used. Otherwise, a new figure is created.
labelstr or array_like of str, optional: If present, replace automatically generated label(s) with given label(s). If sysdata is a list, strings should be specified for each system.
legend_locint or str, optional: Include a legend in the given location. Default is ‘upper left’, with no legend for a single response. Use False to suppress legend.
rcParamsdict: Override the default parameters used for generating plots. Default is set by config.defaults['ctrlplot.rcParams'].
show_legendbool, optional: Force legend to be shown if True or hidden if False. If None, then show legend when there is more than one line on the plot or legend_loc has been specified.
titlestr, optional: Set the title of the plot. Defaults to plot type and system name(s).
