Stateflow

Drawing Objects

A state diagram comprises seven types of graphical objects: states, boxes, functions, transitions, default transitions, history junctions, and connective junctions. Stateflow provides tools for creating instances of each of these types of objects as shown in the following:

In general, you can draw a chart object by first selecting one of the tools and then click-dragging on the chart area to form the object. This rule has two exceptions:

• Transitions do not require the preselection of a drawing tool.

• The Transition tool, used to draw transitions, is available by default. You can click-drag a transition at any time without selecting an icon in the Stateflow editor's object palette.

• Junctions require only a single click to place them at the cursor's position.

For detailed information on creating Statechart objects, see the following topics:
