How do I modify the default junction size for the Stateflow Editor?

I would like my Stateflow charts to have a default junction size that is different from the current defaults.

The ability to change the default junction size for the Stateflow Editor is not available in Stateflow since there are no chart- or machine-level properties controlling these. As a workaround, write functions to modify properties for objects created in MATLAB code as follows:

sfnew

save_system(gcs,'un1')

rt = sfroot;

m = rt.find('-isa','Stateflow.Machine','Name','un1');

chart = m.findDeep('Chart')

%get a handle to the junction

   j = Stateflow.Junction(chart)

   jp = j.Position

   jp.Radius = 25 %Modify the Radius

For information on the default chart level properties that can be modified, refer to the solution linked below:
