Google visualization 谷歌绘制的时间轴不是按时间顺序排列的

我使用谷歌图表折线图作为价格图。每天都有一个值，或者缺少一些天

图形不是一个函数，而是一条曲线。我的意思是图表上有一个卷曲，它可以追溯到时间。从一月底到二月乞讨之间有点不对劲。

图中所示为或：

我相信我使用了正确的日期时间格式日期（2014,01,31）

---

我不明白我做错了什么。

最后我发现了一个问题。正如a所说，月份是以零为基础的。这意味着2014年2月28日不是“日期（2014,2,28）”，而是“日期（2014,1,28）”

---

现在它可以工作了。

我认为格式应该是

new Date（）

：new Date（）不适用于json格式。我终于找到了答案，见下文。
