悬停效应(D3图)

Question

好吧，我试着模仿这个图表上的CSS效果：

当你在一个点上盘旋时，它会在点周围形成一个更大的圆圈。

对于我的生活，我不知道我在我自己的CSS中缺少了什么:)

CSS：

/* Line Chart CSS */

.axis path,
.axis line {
  fill: none;
  stroke: #000;
  stroke-width: 3px;
  shape-rendering: crispEdges;
}

#pipeline-1,

  stroke-width: 1.5px;
  stroke-linecap: round;

.x.axis path {
/* Uncomment below if I want to remove x-axis line */
/*  display: none;*/

你已经填充了你的圆圈，但它们没有笔画颜色。所以，您的css动画正在运行，没有什么可看的：

.pipelinePoint .circlePoint.active {
  fill: orangered;
  stroke: orangered;
  fill-opacity: 1;
  stroke-width: 25px;
  stroke-opacity: .5;
}
