Overview of the Stateflow API

Create and edit Stateflow charts by using MATLAB commands.

Access Properties and Methods of Stateflow Objects

Use dot notation to refer to API properties and methods.

Create and Destroy Stateflow Objects

Add and delete Stateflow objects to your chart.

Access Existing Stateflow Objects

Create handles to manipulate Stateflow objects in your chart.

Copy and Paste Stateflow Objects

Access the clipboard object to duplicate Stateflow objects.

View Stateflow Graphical Objects

Use the fitToView method to zoom in on an object in your chart.

Move Stateflow Graphical Objects

Programmatically reposition states and subcharts.

Modify the Graphical Properties of Your Chart

Access the Editor object to perform graphical operations on a chart.

Create Default Transition Objects

Indicate which substate becomes active during state initialization.

Create Supertransition Objects

Connect transitions between different levels in a chart.

Enter Multiline Labels in States and Transitions

Specify more than one line of text in your state and transition labels.
