Stateflow

Creating a Subchart

You create a subchart by converting an existing state, box, or graphical function into the subchart. The object to be converted can be one that you have created expressly for the purpose of making a subchart or it can be an existing object whose contents you want to turn into a subchart.

To convert a new or existing state, box, or graphical function to a subchart:

1. Select the object and right-click a state (SC1 in the example below) to display the Stateflow shortcut menu for that state.

   

2. Select Subcharted from the Make Contents menu.

1. Stateflow converts the selected state, graphical function, or box to a subchart.

   

Note    When you convert a box to a subchart, the subchart retains the attributes of a box. In particular, the resulting subchart's position in the chart determines its activation order (see Using Boxes in Stateflow Charts for more information).

To convert the subchart back to its original form, right-click the subchart. In the pop-up menu that results, select Make Contents. In the resulting submenu select the Subcharted item.

Caution    You cannot undo the operation of converting a subchart back to its original form. When you perform this operation, the undo and redo buttons are disabled from undoing and redoing any prior operations.
