我正在尝试使用具有不同数据的相同脚本在同一页面上创建 3 个响应式条形图。
当窗口大小调整时，我的问题就出现了。我不断遇到仅在要渲染的最后一个图表中更新的元素。
我很抱歉没有提供 jsfiddle，但我无法让 fiddle 渲染我的代码(fiddle - newbee)
以下代码片段仅生成轴'。我遇到的第一个问题是 d3.axisBottom(scale) - 作为我遇到的示例。

最佳答案
我也被同样的问题困扰。我知道您找到了解决方案，但我想我会提供我发现的内容，以防它对最终访问此页面的其他人有所帮助，因为这个问题比我发现的其他问题更准确地描述了我的问题。
我的解决方案最终来自以下 Stack Overflow 帖子。那里的答案解释说您需要为监听器添加命名空间，否则在添加新监听器时现有监听器将被删除。
How to have multiple d3 window resize events
对于这个例子，我必须更改此代码:
d3.select(window).on("resize", render);
到
var resizeId = "resize." + scope.chartId
d3.select(window).on(resizeId, render);
其中scope.chartId是每个图表的唯一ID，因此监听器也是唯一的，并且在添加新图表时不会被删除。
