【问题描述】:
我有一个具有向下钻取功能的分组列高图。这是针对学区的,所以我的分组列是小学、初中和高中水平统计数据的上一年/当年。您可以单击任何列进行深入研究,并查看各个学校的表现。导出图表后,我尝试根据选择的学校级别进行一些更改——图表的宽度和高度、x 轴类别和类别旋转。
我希望能够在 chart.events 部分中动态地进行这些更改,但它似乎不起作用。我最初是初始图表构建之外的动态变量,并且正在使用这些值。显然我做的不对。有没有更简单的方法来更新我不知道的导出方法的这些值?
我已经创建了图表的jsFiddle,这样您就可以看到正在发生的事情......您可以一如既往地提供任何帮助,我们将不胜感激!
