Examples of IntervalXYDataset

com.positive.charts.data.xy.IntervalXYDataset
An extension of the {@link XYDataset} interface that allows a range of datato be defined for the X values, the Y values, or both the X and Y values. This interface is used to support (among other things) bar plots against numerical axes.
org.jfree.data.xy.IntervalXYDataset
An extension of the {@link XYDataset} interface that allows an x-intervaland a y-interval to be defined. Note that the x and y values defined by the parent interface are NOT required to fall within these intervals. This interface is used to support (among other things) bar plots against numerical axes.
