I have a state machine in my core model which has local and output signals Log signal data enabled. I want to disable that option and need to save the model. I have used the below code but still I was not able to save the changes to the model.

mdl = 'Modelname';

mi = Simulink.SimulationData.ModelLoggingInfo.createFromModel('mdl');

for i = 1:numel(mi.Signals)

mi.Signals(i).LoggingInfo.DataLogging = 0;

end

set_param(mdl, 'DataLoggingOverride', mi);

You can follow the steps below to disable log signal data option as follows:

Open the model in Simulink.
Open the Stateflow Chart from the model and now open the Symbols Pane from the Simulation tab in Prepare Section.
Similarly Open the Property Inspector from the Simulation Tab in Prepare Section.
Now select the data or signal whose Logging is be removed from the Symbols Pane.
Now In the Property Inspector, under Logging, uncheck the log signal data check box to disable the logging.
Now save the model by pressing ctrl + S or using the save button present in the Simulation Tab under File section.
