Question

我对D3 JS还是很陌生，我已经使用StackOverflow的一些资源创建了多线D3图表。我已经附上了该代码。我的问题是在图表中，我需要在X轴上显示从当月到上一年的同月的13个月。在那种情况下，我遇到了几个问题，最后想到了这个。现在不存在另一个问题，例如我需要支持月份名称的本地化。但是由于我将时间序列用于x轴，因此当我将月份名称更改为另一种语言时会出现错误。我希望如果我将非时间序列用于X轴，不会出现此问题？有没有办法转换为非时间序列？

我认为您只需要重新格式化小提琴中的数据即可。在数组的前3个对象中，缺少有关它们来自哪一年的指示：

var data = [{
    name: "USA",
    values: [{
        date: "October",
        price: "100"
      },
      {
        date: "November",
        price: "110"
      },
      {
        date: "December",
        price: "145"
      },
      {
        date: "2011-January",
        price: "241"
      },

Here is your fiddle again，其中我更改了这些日期行，并在x轴上添加了该月所属年份的指示，并更改了该轴的字体大小文字彼此重叠。

在D3图表中将Xaxis值显示为非时间序列值
