D3.js 未触发堆叠栏 OnClick 操作
D3.js Stacked Bar OnClick Action Not Triggered
我正在创建两个相关的堆积条形图。单击顶部图表的条形应触发底部图表的绘制。奇怪的是，mouseover 和 mousemove 操作有效，但 click 操作无效。我需要更改什么才能使点击操作生效？
注意：在说我不尊重代码中的 "Do Not Repeat Yourself Principle" 之前，请记住 Kent Beck 说过："First, get it to work, then get it right, finally get it to work fast"。我仍处于开始工作阶段。
请随意跳过数据创建部分。
这是我的代码：
