Extending Stateflow Chart Diagrams

This chapter takes you through the steps of extending Stateflow states, transitions, and junctions with subcharts, boxes, functions, and notes. It includes the following sections:

Using History Junctions to Extend Charts and States	Describes how to create, move, and specify properties for Stateflow history junctions. History junctions extend the abilities of charts and states by recording their most recently active substate.
Using Subcharts to Extend Charts	Shows you how to create and work with charts within charts, that is, subcharts. Subcharts are a convenience for compacting your diagrams.
Using Supertransitions to Extend Transitions	Shows you how to make a supertransition to connect transitions from outside a subchart to a state or junction inside a subchart.
Extending Transitions with Smart Behavior	Shows you how smart transitions maintain their shapes and uniqueness while you rearrange chart objects.
Using Functions to Extend Actions	Describes how Stateflow graphical functions are created, called, and made available to Simulink. Graphical functions are a convenience, as functions are to programs.
Using Boxes to Extend Chart Diagrams	Describes Stateflow boxes and how to create them in your new chart. Boxes are a convenience for grouping items in your charts.
Using Notes to Extend Chart Diagrams	Shows you how to create, edit, and delete descriptive notes for your Stateflow chart.
Reporting Chart Diagrams	Shows you the options Stateflow offers for printing part or all of your Stateflow chart.
