Rename and update the references to the chart output y.

Open the model and access the Stateflow.Data object for the chart output y.

open_system("sfRectifyAPIExample")
data = find(sfroot,"-isa","Stateflow.Data",Scope="Output");
data.Name

ans = 
'y'

Find the locations where the chart refers to the chart output.

references = getReferences(data)

references=2×1 SymbolReference array with properties:
    Position
    WhereUsed

Display the names and entry actions of the states that refer to the chart output.

whereUsed = [references.WhereUsed];
classes = arrayfun(@class,whereUsed,UniformOutput=false);
idx = (classes=="Stateflow.State");
states = whereUsed(idx);
get(states,{"Name" "EntryAction"})

ans = 2x2 cell
    {'On' }    {'y = x;'}
    {'Off'}    {'y = 0;'}

Change the Name property of the chart output to "z" and update the references to the output in the chart.

renameReferences(data,"z")
data.Name

ans = 
'z'

Display the names and modified entry actions of the states that refer to the chart output.

get(states,{"Name" "EntryAction"})
