highcharts Highchart鼠标跟踪

我正在使用Highchart组织结构图，我想更改鼠标跟踪的行为。在这段代码中，当您将鼠标悬停在节点上时，将只显示第一个父节点和第一个子节点。我想要的是，当你悬停一个节点时，所有相关的父节点和子节点都将显示出来。例如，现在，如果你悬停在'首席财务官'，只有'首席执行官'和'营销团队'显示。但是我想看到所有相关的节点，比如〈股东+董事会+ CEO +营销团队〉。你能帮我实现这个愿望吗非常感谢。

                    nodeId = point.toNode.id,
                    nodeDesc = nodeName === nodeId ? nodeName : nodeName + ', ' + nodeId,
                    parentDesc = point.fromNode.id;
                return point.index + '. ' + nodeDesc + ', reports to ' + parentDesc + '.';

        Organization charts are a common case of hierarchical network charts,
        where the parent/child relationships between nodes are visualized.
        Highcharts includes a dedicated organization chart type that streamlines
        the process of creating these types of visualizations.

此功能不是现成可用的，但您可以通过编写一个算法来实现，该算法将检查节点之间的关系，并在point.mouseOver()和point.mouseOut()事件上更新其不透明度。以下是我的解决方案：

plotOptions: {
    series: {
      states: {
        inactive: {
          opacity: 1
        }
      },
      point: {
        events: {
          mouseOver() {
            let parents = [];
            let children = [];
            let hovered = this;
            const getParents = (node) => {
              if (node.linksTo) {
                node.linksTo.forEach(link => {
                  let parent = node.series.nodes[link.fromNode.index];
                  parents.push(parent);
                  getParents(parent);
                });
              }
            }

            const getChildren = (node) => {
              if (node.linksFrom) {
                node.linksFrom.forEach(link => {
                  let child = node.series.nodes[link.toNode.index];
                  children.push(child);
                  getChildren(child);
                });
              }
            }

            getParents(hovered);
            getChildren(hovered);

            const family = parents.concat(hovered, children);

            this.series.nodes.forEach(node=> {
                             node.update({
                opacity: 0.1
              }, false)
            });

            family.forEach(node => {
              node.update({
                opacity: 1
              }, false)
            })

            this.series.chart.redraw();
          },
          mouseOut() {
                      this.series.nodes.forEach(node=> {
                             node.update({
                opacity: 1
              }, false)
            });

            this.series.chart.redraw();
          }
        }
      }
    }
  },
