Examples of org.jfree.data.xy.XYSeries

org.jfree.data.xy.XYSeries
Represents a sequence of zero or more data items in the form (x, y). By default, items in the series will be sorted into ascending order by x-value, and duplicate x-values are permitted. Both the sorting and duplicate defaults can be changed in the constructor. Y-values can be null to represent missing values.
