示例1: createXYSeriesCollection

import org.jfree.data.xy.XYSeriesCollection; //導入方法依賴的package包/類
/**
 * @param valueSource
 * @param plotInstance
 * @param autoWidthFraction
 *            If this value is greater than 0, an auto width for the intervals is calculated
 *            such that the intervals nearest to each other touch. This value is then multiplied
 *            with the value of autoWidthFtraction. If unset, the intervals have width 0.
 * @param allowDuplicates
 * @param sortByDomain
 *            if true, the data is sorted by domain values (useful for bar and area charts)
 * @return
 * @throws ChartPlottimeException
