我试图通过一次又一次地更改parseDate函数参数但仍然没有结果来解决此错误（“ d3.min.js：1 Uncaught TypeError：n.getFullYear不是一个函数”），当我通过d.date解析日期时forEach函数日期变为空，这就是为什么在svg路径中，其以“ NaN”作为输入，导致没有绘制多系列折线图的原因。
//JSON array called "somearray" is like this.Actual JSON Array is much bigger but just to show the problem i have given this much.
