public class NFBarSet

extends NFDataSet

An NFBarSet describes a single set of 1 dimensional data along with its appearance characteristics. Data can be added via the addElement(), setElementAt(), or loadDataModel() methods. A simple example of this object's usage is shown here:

	NFBarchart bc = new NFBarchart();
	NFBarSet barSet = new NFBarSet("Apples", Color.red);
	for (int j=0; j < 20; j++)
		barSet.addElement(j);
	barSet.setBarType(NFBarSet.TRIANGLEBAR);

	bc.addBarSet(barSet);
