D3切换堆叠在多个条形图上分组

Question

我正在尝试在一个页面上运行多个“堆叠到分组”的d3条形图。我可以让图表渲染，但是没有成功地使两个图表在各个选项之间切换。

我猜这可能与多次调用“更改”函数有关（因为我在渲染两个图表时都调用它），但我不知道如何将它放在图表并使其能够访问所需的内容。认为它可能与“每个”有关，但我不确定。

以下是我创建的jsfiddle的链接：http://jsfiddle.net/1amsknh2/

这是图表的js：

    chart1();

在这里和那里挣扎之后，我终于为你做了一个小提琴。检查一次。我希望你正在寻找这个http://jsfiddle.net/jxbyf82u/ 在这个小提琴中观察这些线

d3.selectAll("input").on("change", change1);
chart1.change1 = change1;

我通过传递输入值（如下面的

）从chart2（）的change（）函数调用此函数

chart1.change1(this.value);

如果它不是你想要的，那么问你想要什么。好的
