iddataPlotOptions
(Not recommended) Option set for plot
when plotting data
contained in an iddata
object
iddataPlotOptions
is not recommended. Use dataPlotOptions
instead to create option sets for idplot
. For more information, see Compatibility Considerations.
Syntax
Description
creates
the default option set for plotting time-domain data. Use dot notation to customize
the option set, if needed.opt
= iddataPlotOptions('time')
creates a default option set for plotting frequency-domain data. Use dot notation to
customize the option set, if needed.opt
= iddataPlotOptions('frequency')
initializes the plot options with the System Identification Toolbox™
preferences. This syntax can include any of the input argument
combinations in the previous syntaxes. Use this syntax to change a few plot options
but otherwise use your toolbox preferences.opt
= iddataPlotOptions(___,'identpref')
Examples
Create Option Set for Plotting Time-Domain Data
Create an option set and use it for plotting data
% Create Option Set opt = iddataPlotOptions('time'); opt.TimeUnits = 'minutes'; % Turn grid on opt.Grid = 'on'; % Load input/output data and plot it. load iddata1 z1 h = plot(z1, opt);
Change Orientation of Input-Output Data Axes
Generate data with two inputs and one output, plot the data, and change the orientation of the plots.
% Generate the data set. z = iddata(randn(100,1),rand(100,2)); % Configure a time plot. opt = iddataPlotOptions('time'); % Plot the data. h = plot(z,opt); % Change the orientation of the % plots such that all inputs are plotted in one column, % and all outputs are in a second column. opt.Orientation = 'two-column'; h = plot(z,opt); % Alternatively, use setoptions. setoptions(h,'Orientation','two-column')
Create Option Set for Plotting Frequency-Domain Data
Create an option set with default options for frequency-domain data.
opt = iddataPlotOptions('frequency'); % Specify plot properties, such as phase visibility and frequency units. opt.PhaseVisible = 'off'; opt.FreqUnits = 'Hz'; % Create a plot with the specified options. load iddata7 z7 zf = fft(z7); h = plot(zf,opt);
Initialize a Plot Using Toolbox Preferences
Specify identpref
for standard
preferences.
opt = iddataPlotOptions('time','identpref');

Version History
Introduced in R2014aR2023a: iddataPlotOptions
is not recommended
iddataPlotOptons
is not recommended. Use dataPlotOptions
instead to create option sets for idplot
, which replaces plot
.
iddataPlotOtions
continues to work with
plot
. There are no plans to remove
iddataPlotOptions
at this time.
