setoptions(h,Name=Value)

setoptions(h,opts,Name=Value)

Description

setoptions(h,opts) sets options for the plot associated with plot handle h to the options specified in opts.

setoptions(h,Name=Value) specifies one or more plot options using name-value arguments. For example, setoptions(sp,FreqUnits='rad/s') sets the frequency units of spectrum plot sp to radians per second.

To see the supported options for a specific plot type, see the corresponding options page indicated in opts.

Obtain the identified model.

load iddata9 z9
sys = ar(z9,4);

Get the plot handle for the model spectrum plot.

h = spectrumplot(sys);

Figure contains an axes object. The axes object with title From: e@y1 To: y1, ylabel Power (dB) contains an object of type line. This object represents sys.

(Optional) Specify the plot options, using the plot handle.
