【问题描述】：

我想组合 2 个或多个折线图，其中 x 轴为日期，y 轴为值。但是某些系列的日期不匹配。

series0X= ["2015-11-21","2017-09-21"];
series1X= ["2017-09-21","2017-10-22","2017-11-20"];
series2X= ["2018-05-21","2018-09-22","2018-10-20","2018-11-21"]

series0Y=["5","8"];
series1Y=["3","4","7"];
series2Y= ["2","9","6","1"];

我已经对 x 轴的日期数组进行了合并和排序：

DatesX = ["2015-11-21", "2017-09-21", "2017-10-22", "2017-11-20", "2018-05-21", "2018-09-22", "2018-10-20", "2018-11-21"];

我希望 y 轴系列值是这样的：

series0Y= ["5","8","0',"0","0", "0", "0", "0"]
series1Y= ["0","3","4',"7","0", "0", "0", "0"]
series2Y= ["0","0","0',"0","2","9","6","1"]

【解决方案1】：

使用null 而不是0 作为缺失数据的值。就我而言，效果很好
