plot

Class: Simulink.sdi.DatasetRef
Package: Simulink.sdi

Open the Simulation Data Inspector to view and compare data

Syntax

SDIDatasetRef.plot

Description

SDIDatasetRef.plot opens the Simulation Data Inspector, where you can view and compare runs and signals.

Examples

This example shows how to work with the Simulink.sdi.DatasetRef object by comparing two runs of the ex_sldemo_absbrake system with different desired slip ratios.

% Simulate model ex_sldemo_absbrake to create a run of logged signals
load_system('ex_sldemo_absbrake')
sim('ex_sldemo_absbrake')

% Get the runID
runIDs = Simulink.sdi.getAllRunIDs;
runID = runIDs(end);

% Get the run object
brakeRun = Simulink.sdi.getRun(runID);

% Make a Simulink.sdi.DatasetRef object
run_DSRef = brakeRun.getDatasetRef;

% Get the names of the elements in the object
names = run_DSRef.getElementNames
names = 2x1 cell array
    {'yout'}
    {'slp' }

% Get yout bus
[yout, name, index] = run_DSRef.getElement(1);

% View signals in outputs
outputs = yout.Values
outputs = struct with fields:
    Ww: [1x1 timeseries]
    Vs: [1x1 timeseries]
    Sd: [1x1 timeseries]

% Get slp signal
slp = run_DSRef.getSignal('slp');

% Plot signal
slp.Checked = 'true';
% Create another run for a different Desired relative slip
set_param('ex_sldemo_absbrake/Desired relative slip', 'Value', '0.25')
sim('ex_sldemo_absbrake')
DSR_Runs = Simulink.sdi.DatasetRef;

% Compare the results from the two runs
[matches, mismatches, diffResult] = run_DSRef.compare(DSR_Runs(2));

% Open the Simulation Data Inspector to view signals
run_DSRef.plot

Alternatives

You can use the Simulink.sdi.view function to open the Simulation Data Inspector. For information on using the UI to open the Simulation Data Inspector, see View Data with the Simulation Data Inspector.
