问题描述
在此高位图表中： :
是什么原因使x轴值出现在每个点中的年份增加了+10？
我可以看到起点设置为1940，xAxis配置为返回this.value，但是似乎有一些隐式功能计算每年的值？
要更改显示时间范围而不是1940-2000 ...的一年12个月... 小提琴代码：

更新：如何显式提供x值到图表？
1楼
为了说明我的评论中的问题：
1）使用datetime x轴类型，并提供一个pointStart和pointInterval
或明确提供x值：
（日期可以由Date.UTC对象[记住，javascript计数从0开始的月份数]，也可以是[epoch]时间戳[以毫秒为单位]的引用： | ）
2）使用类别：

我进行了以下更改：

希望它能工作..
