当我将鼠标悬停在Google图表中的某个点上时,我遇到了更改日期工具提示的问题。你可以在这里找到它:http://jsfiddle.net/5smu5ng7/15/

As you can see, the tooltips read "Feb 1, 2017". I want them to just read "February 2017", but I can't seem to get it right.

如您所见,工具提示显示为“2017年2月1日”。我希望他们只读“2017年2月”,但我似乎无法做到正确。

根据Google Charts网站的说法,我所包含的以下细分应该可以解决问题,但它不会:

      hAxis: {
         format: 'MMMM/yyyy'
      }

How do I get it to work?

我如何让它工作?
