Simulink.sdi.copyRunViewSettings

Copy line style and color for signals from one run to another

Syntax

sigIDs = Simulink.sdi.copyRunViewSettings(run1,run2,plot)

Description

sigIDs = Simulink.sdi.copyRunViewSettings(run1,run2,plot) copies the line style and color specifications from runID1 to runID2 for matched signals. You can specify run1 and run2 with their run ID or as a Simulink.sdi.Run object. If plot is specified as true, Simulink.sdi.copyRunViewSettings also changes signal parameters in both runs so that aligned signals that are plotted come from the run2. The function returns an array of signal identifiers for the signals that the Simulation Data Inspector aligned between the two runs. To learn more about how the Simulation Data Inspector aligns signals between runs, see How the Simulation Data Inspector Compares Data.

Open Live Script

Copy view settings from one run to another and create figures using the Simulink.sdi.CustomSnapshot object.

Simulate Model and Get Run Object

Configure the vdp model to save output data. Run a simulation to create data. 

load_system("vdp")
set_param("vdp","SaveFormat","Dataset","SaveOutput","on")
set_param("vdp/Mu","Gain","1");
sim("vdp");

Use the Simulation Data Inspector programmatic interface to access the run data.

runIndex = Simulink.sdi.getRunCount;
runID = Simulink.sdi.getRunIDByIndex(runIndex);
vdpRun = Simulink.sdi.getRun(runID);

Modify Signal View Settings

Use the Simulink.sdi.Run object to access signals in the run. Then, modify the signal view settings. This example specifies the line color and style for each signal. The view settings for the run comprise the view settings for each signal and view settings specified for the plot area.

sig1 = getSignalByIndex(vdpRun,1);
sig2 = getSignalByIndex(vdpRun,2);

sig1.LineColor = [0 0 1];
sig1.LineDashed = "-.";

sig2.LineColor = [1 0 0];
sig2.LineDashed = ":";

Capture Snapshot from Simulation Data Inspector

Create a Simulink.sdi.CustomSnapshot object and use the Simulink.sdi.snapshot function to programmatically capture a snapshot of the contents of the Simulation Data Inspector.

snap = Simulink.sdi.CustomSnapshot;

You can use properties of the Simulink.sdi.CustomSnapshot object to configure the plot settings, such as the subplot layout and axis limits, and to plot signals. When you use a Simulink.sdi.CustomSnapshot object to create your figure, these plot settings do not affect the Simulation Data Inspector.

snap.Rows = 2;
snap.YRange = {[-2.25 2.25],[-3 3]};
plotOnSubPlot(snap,1,1,sig1,true)
plotOnSubPlot(snap,2,1,sig2,true)

Use the Simulink.sdi.snapshot function to generate the figure you specified in the properties of the Simulink.sdi.CustomSnapshot object.

fig = Simulink.sdi.snapshot("From","custom","To","figure","Settings",snap);

Figure contains 2 axes objects. Axes object 1 with xlabel Time (seconds) contains an object of type line. This object represents x1. Axes object 2 with xlabel Time (seconds) contains an object of type line. This object represents x2.

Copy View Settings to New Simulation Run

Simulate the model again, with a different Mu value. Use the Simulation Data Inspector programmatic interface to access the simulation data.

set_param("vdp/Mu","Gain",".5")
sim("vdp");

runIndex2 = Simulink.sdi.getRunCount;
runID2 = Simulink.sdi.getRunIDByIndex(runIndex2);
run2 = Simulink.sdi.getRun(runID2);

To create a plot of the new output data that looks like the one you created in the previous step, you can copy the view settings to the run in a single line of code using the Simulink.sdi.copyRunViewSettings function. This function does not automatically update plot settings in Simulink.sdi.CustomSnapshot objects, so specify the input that determines whether the plot updates as false.

sigIDs = Simulink.sdi.copyRunViewSettings(runID,runID2,false);

Capture Snapshot of New Simulation Run

Use the Simulink.sdi.CustomSnapshot object to capture a snapshot of the new simulation run. First, clear the signals from the subplots. Then, plot the signals from the new run and capture another snapshot.

clearSignals(snap)
snap.YRange = {[-2.25 2.25],[-8 8]};
plotOnSubPlot(snap,1,1,sigIDs(1),true)
plotOnSubPlot(snap,2,1,sigIDs(2),true)


fig = snapshot(snap,"To","figure");

Figure contains 2 axes objects. Axes object 1 with xlabel Time (seconds) contains an object of type line. This object represents x2. Axes object 2 with xlabel Time (seconds) contains an object of type line. This object represents x1.

Input Arguments

Run with the view settings you want to copy specified with its run ID or Simulink.sdi.Run object. The Simulation Data Inspector assigns run IDs when it creates runs. You can get the run ID for your run using Simulink.sdi.getAllRunIDs or Simulink.sdi.getRunIDByIndex.

Run you want to copy the view settings to, specified with its run ID or Simulink.sdi.Run object. The Simulation Data Inspector assigns run IDs when it creates runs. You can get the run ID for your run using Simulink.sdi.getAllRunIDs or Simulink.sdi.getRunIDByIndex.

Specifies whether the Simulation Data Inspector changes the plot settings in the runs corresponding to run1 and run2.

  • When plot is true, the Simulation Data Inspector modifies the signal parameters so that the aligned signals that are plotted come from run2.

  • When plot is false, the Simulation Data Inspector does not change which signals are plotted.

Data Types: logical

Output Arguments

collapse all

Matrix containing the signal IDs for signals in run2 that aligned with signals in run1 and had view settings modified.
