(Create output for monitoring:)

Hi @Fangping,

To programmatically check the option “Create output for monitoring” in the Stateflow chart’s properties, you can make use of the “HasOutputData” property of the “Stateflow.Chart” object.

chart.HasOutputData = 1;

The 'OutputMonitoringMode' property can be used to set the mode of the output data.

chart.OutputMonitoringMode = ‘ChildActivity’; 

To access your Stateflow chart object, the “find” function can be used.

chartArray = find(sfroot,"-isa","Stateflow.Chart");

Here’s some documentation to help you out:

'HasOutputData' :

I can take out this chart, but this attribute OutputMonitoringMode just sets the mode. What I'm thinking about is activating Create output for monitoring. You may need to set the OutputData property, but this property is read-only. Is there any way?

[Divyajyoti Nayak]

Oh my mistake, then instead of the 'OutputMonitoringMode' property, you can use the 'HasOutputData' property. I'll edit the answer above.

Yes, you can remove the check box with this setting

chart.HasOutputData = 0;

This is the mode for modifying it

chart.OutputMonitoringMode = ‘ChildActivity’;
