Simulink.sdi.plot - Plot data in Simulation Data Inspector - MATLAB (original) (raw)

Plot data in Simulation Data Inspector

Syntax

Description

Simulink.sdi.plot([obj](#mw%5Fc0a3abf9-7c5f-4e17-9db2-6bb2834871f8)) opens the Simulation Data Inspector and plots the data in the object obj.

When the input object contains fewer than eight signals, the Simulation Data Inspector layout changes to 1-by-n, where n is the number of signals, and each subplot displays one signal. When the simulation results contain more than eight signals to plot, the Simulation Data Inspector layout changes to1-by-1, and the plot displays the first signal.

example

Simulink.sdi.plot([obj](#mw%5Fc0a3abf9-7c5f-4e17-9db2-6bb2834871f8),[runName](#mw%5Fb044efe1-74c9-4b24-94bf-06c3e6565233)) names the run runName when the data in obj does not already exist as a named run in the Simulation Data Inspector. If the data inobj already exists as a named run in the Simulation Data Inspector, the run is not renamed.

Simulink.sdi.plot([data](#mw%5F16253ff7-9ce2-48ce-85b0-dee1dc3ca2e1),[time](#mw%5F938f0b85-4bd3-43ce-86d6-52fc0c848e84)) plots data with respect to time in the Simulation Data Inspector.

example

[runObj](#mw%5F8b263d3c-f0da-4ca8-bc66-f9b19787c88a) = Simulink.sdi.plot(___) returns the Simulink.sdi.Run object that corresponds to the plotted data.

Examples

collapse all

You can use the Simulink.sdi.plot function to plot simulation results in the Simulation Data Inspector. Open the model vdp, which models the second-order Van der Pol differential equation. For more information about the model, see Van der Pol Oscillator.

mdl = "vdp"; open_system(mdl)

The vdp model

Simulate the model. The model logs two signals: x1 and x2. Simulation results are stored in a single SimulationOutput object named out.

Use the Simulink.sdi.plot function to open the Simulation Data Inspector and plot the results.

Simulation results are plotted on two vertically aligned subplots in the Simulation Data Inspector. The x1 signal is plotted in the upper subplot. The x2 signal is plotted in the lower subplot.

You can use the Simulink.sdi.plot function to plot data with respect to time in the Simulation Data Inspector.

time = 0:0.1:10; data = sin(time); Simulink.sdi.plot(data,time);

A single sine wave plotted in the Simulation Data Inspector

You can also plot an array of data values in the Simulation Data Inspector. The number of rows in the data array must match the length of the time vector. The number of columns in the data array corresponds to how many signals are plotted.

dataArray = rand(length(time),4); Simulink.sdi.plot(dataArray,time);

Input Arguments

collapse all

Run name, specified as a string or character vector.

The software only applies the run name runName to an unnamed run. If a named run with some or all of the data in obj already exists in the Simulation Data Inspector, the run is not renamed. When you create a run by simulating a model that logs data, the run name is automatically generated according to the run-naming rule in the Simulation Data Inspector. You can modify the run-naming rule in the Simulation Data Inspector in the UI or by using the Simulink.sdi.setRunNamingRule function.

To rename a run, you can use the Name property. For example,myRun.Name = myRunName sets the Name property of the Run object myRun tomyRunName. The workspace variable name for the run (myRun) does not change when you set the Name property.

Sample times, specified as a numeric scalar or vector, or a cell array of date character vectors. The table lists forms for valid date character vectors.
