javascript - 防止图像旋转到 d3 径向树上的 SVG 圆中

标签 javascript svg d3.js

我使用的是 d3js 简单树径向图，并且我在深度 1 上添加了带有 SVG 图像的额外圆圈，但图像会平移并旋转到圆圈位置。

如何保留或旋转图像以查看原始位置(即垂直模式)？

这是我的虚拟代码:

最佳答案

这就是你想要的吗？

我添加了以下代码:

nodeUpdate.selectAll(".circle_1").attr("transform", function(d) {
  return "rotate(" + (-1 * d.x + 90) + ")";
});

这将选择所有深度为 1 的圆(基于 circle_1 的类)并“取消旋转”它们。

注意:在以下代码中:

nodeEnter.filter(function(d) {
    return d.depth == 1;
  })
  .append("circle")
  .attr("r", "1.2em")
  .style("fill", "gray")
  .attr("class", function(d) {
    return "circle_" + d.depth
  })
  .attr("id", "circle_group")
  .attr("stroke", "#CCC")
  .attr("stroke-width", 2)
  .attr("pointer-events", "none")
  .style("fill", "url(#group_avatar)");

您正在重复使用 ID circle_group，从技术上讲，您不应该这样做，但在这种情况下，它不会给您带来任何问题。
