ComponentGroup

public class XRangeChart<X,Y>
extends Object
implements ComponentGroup

X-range chart. X-range charts are used to visualize a range on the X-axis. It is plotted on a RectangularCoordinate system a range of values on the X-axis with corresponding Y-axis values. Each X range-value is represented using a horizontal bar. Typically, X-values are of DataType.NUMBER, DataType.DATE or DataType.TIME and Y-values are of DataType.CATEGORY. However, the Y-values could be of other types too.

Note: This chart automatically creates its coordinate system and the required axes.
