我正在尝试根据所选持续时间的小时创建移动平均线。我希望x轴代表一天中的24小时，而y轴代表整个持续时间内每小时的平均值。例如，我想要一个人努力的四月份的小时平均值。
我编写了以下程序，但它在第一个程序后两天打印。任何帮助都非常感谢。

答案 0 :(得分：1)
根据我的评论理解，你真的想在你的情节上展示4个系列，而不是2 - 即
然后，您可以更改getDateByHour()方法，或者更好地与new Hour(Date)中多次调用的createDataset()构造函数结合使用：
private Hour makeHour(int hour) {
return new Hour(hour, 1, 1, 2012);
}
您使用的实际日/月/年不重要，因为您已将DateFormat设置为＆＃34; HH＆＃34;，因此不会呈现任何内容。 （假设你以后不改变x轴......）
