setoptions
Set plot options for response plot
Syntax
setoptions(h, PlotOpts)
setoptions(h, 'Property1', 'value1', ...)
setoptions(h, PlotOpts, 'Property1', 'value1', ...)
Description
setoptions(h, PlotOpts) sets preferences
for response plot using the plot handle. h is the
plot handle, PlotOpts is a plot options handle
containing information about plot options.
There are two ways to create a plot options handle:
Use
getoptions, which accepts a plot handle and returns a plot options handle.p = getoptions(h)
Create a default plot options handle using one of the following commands:
bodeoptions— Bode plotshsvoptions— Hankel singular values plotsnicholsoptions— Nichols plotsnyquistoptions— Nyquist plotspzoptions— Pole/zero plotssigmaoptions— Sigma plotstimeoptions— Time plots (step, initial, impulse, etc.)
For example,
p = bodeoptions
returns a plot options handle for Bode plots.
setoptions(h, 'Property1', 'value1', ...) assigns
values to property pairs instead of using PlotOpts.
To find out what properties and values are available for a particular
plot, type help <function>options.
For example, for Bode plots type
help bodeoptions
For a list of the properties and values available for each plot type, see Properties and Values Reference (Control System Toolbox).
setoptions(h, PlotOpts, 'Property1', 'value1', ...) first
assigns plot properties as defined in @PlotOptions,
and then overrides any properties governed by the specified property/value
pairs.
Examples
Change Frequency Units in Response Plot
Create the following continuous-time transfer function:
sys = tf(1,[1 1]);
Create a Bode plot with plot handle h.
h = bodeplot(sys);
Create a plot options handle p.
p = getoptions(h);
Change frequency units of the plot to Hz.
p.FreqUnits = 'Hz';Apply the plot options to the Bode plot.
setoptions(h,p);
Alternatively, use setoptions(h,'FrequencyUnits','Hz').
