simulink plot and compare

i use autonomous-emergency-braking-with-sensor-fusion.

and i use sim("AEBTestBench"); % Simulate to end of scenario

helperPlotAEBResults(logsout,scenarioFcnName);

this code to plot.

i want change parameter and compare before change parameter and after change parameter in plot.

How can i compare two graphs (like matlab hold on)

(1) I can see you are working with the example below.

Autonomous Emergency Braking with Sensor Fusion - MATLAB & Simulink - MathWorks 한국

(2) The plot itself is complicated and it would be hard to compare by overlapping signals in the same figure. In my humble opinion, it would be better (or may be recommended) to use different figures to compare the result. This is exactly how it is done in the example as well. The author uses scenario names to set up environment and plot results in new figures. For example,

helperSLAEBSetup(scenarioFcnName="scenario_25_AEB_PedestrianTurning_Nearside_10kph");
sim("AEBTestBench");
helperPlotAEBResults(logsout,scenarioFcnName);

and

helperSLAEBSetup(scenarioFcnName="scenario_23_AEB_PedestrianChild_Nearside_50width");
sim("AEBTestBench");
helperPlotAEBResults(logsout,scenarioFcnName);

(3) Another way is to use the result logs called "logsout". You can keep them by parameters for comparison.

Hope this helps.
