XYPlot.indexOf介绍

[英]Returns the index of the specified dataset, or -1 if the dataset does not belong to the plot.
[中]返回指定数据集的索引，如果数据集不属于绘图，则返回-1。

 * renderer with the same index as the dataset or, if there isn't a

 * does not belong to the plot, this method will return {@code null}.
 *
 * @param dataset  the dataset ({@code null} permitted).
