Javascript Highcharts：从特定范围开始绘制yAxis值

我正在使用highstocks，我想知道是否有任何方法可以从任意数字开始绘制列序列中的y值。例如我有一个名为NU（新用户）的列系列，它的第一个条目yAxis值为1000。目前，第一个条目从[0，1000]范围绘制在yAxis上。但我希望它是从[50006000]开始绘制的

我之所以要这样做，是因为NU本质上是另一个名为DAU（Daily Active Users）的专栏的一部分，我希望它能如此显示。DAU列系列的第一个条目的Y值为6000，6000-1000为5000；因此，我希望NU的这个条目从5000开始

这是我到目前为止所拥有的

我打算将DAU绘制为（原始DAU-NU），并将NU堆叠在DAU的顶部，但这意味着该系列中的DAU值不正确

这是我的密码

您可以对列使用

low

属性，例如：

要显示正确的工具提示，请添加额外的属性，如

val

，并使用pointFormat显示它

注意：当使用数据分组时，自定义属性将被删除，在这种情况下，我建议您创建自己的工具提示格式化程序，以显示您所需的内容。

正是我想要的！
