<%// ChangeOrientation:%>

<%
// A graph's display properties (orientation, title, axis characteristics, and
// so on) are general properties that are defined in the graph's model. Thus,
// to set the orientation of bar elements,
//    1) Get the BarChart's graph model
//    2) Call the model's setOrientation() method
// By default, a BarChart is created with a vertical orientation.
