net.sf.jasperreports.charts.util.JRMeterInterval
Defines a subsection of a meter chart. This section has its own range, a label, and can shade a section of the meter face with its own color. Common usages are to show "critical", "warning" and "good" ranges. @author Barry Klawans (barry@users.sourceforge.net) @version $Id: JRMeterInterval.java 3939 2010-08-20 09:52:00Z teodord $
