示例1: createXYSeriesCollection
import org.jfree.data.xy.XYSeriesCollection; //导入方法依赖的package包/类
/**
* @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
