Using d3-tip and CSS hover effect with d3 stacked bar chart
我正在尝试为一个简单的数据集制作一个堆积的条形图(下面可以找到代码和数据)。
对于鼠标悬停的栏,我尝试使用CSS悬停效果来更改栏的颜色(类为.bar的rect svg元素),并使用d3-tip显示工具提示,以显示该栏的区域名称属于。
我遇到的问题是:
1-CSS悬停效果根本不起作用。 (请在下面找到样式表)
2-显示工具提示,但仅当我从栏下方移动鼠标光标以输入它时才显示。如果我从栏的左/右/顶部移动鼠标光标,似乎无法检测到"鼠标悬停"。如果未检测到它,则单击该条将被检测到并显示工具提示。
3-工具提示应该显示" d.State"的数据(这是该区域的缩写文本),但它给我的定义是不确定的。不过," d.State"与条形图本身配合良好-轴刻度使用这些数据创建。
堆叠的条基于此条制成:https://bl.ocks.org/mbostock/3886208
工具提示和悬停效果基于以下内容:http://bl.ocks.org/Caged/6476579

如果有任何不清楚的部分,请告诉我。我是d3和stackoverflow的新手。谢谢!
CSS悬停效果根本不起作用。(我想不是没有遗漏吗?)
问题是它已经使用d3填充了。 要覆盖它,只需在悬停填充上添加!important
填充:steelblue!重要;
显示工具提示,但仅当我从栏下方移动鼠标光标以输入它时才显示。 如果将鼠标光标从栏的左/右/顶部移动(我的代码没有遇到任何问题?)
我不确定到底是什么问题,但是我猜想,仅当您将鼠标悬停在onmouseover上时,它才会起作用。 因此,如果鼠标指针在生成之前已经在图形上,则不会显示工具提示。
工具提示应该显示" d.State"的数据。
这里的问题是State数据未附加到元素,即d.ages不包含状态值。 绑定数据时只需附加状态值。
