Html Highcharts网络图箭头链接
我正在尝试使用Highcharts创建网络图,如下所示: 但是,在Highcharts网络图模块中,我没有看到任何添加箭头而不是连接节点的线段的选项。是否可以使用Highcharts进行此操作?如果没有,这个用例有更好的替代方案吗?下面是我当前必须渲染网络图的代码Html Highcharts网络图箭头链接,html,css,highcharts,bootstrap-4,Html,Css,Highcharts,Bootstrap 4,我正在尝试使用Highcharts创建网络图,如下所示: 但是,在Highcharts网络图模块中,我没有看到任何添加箭头而不是连接节点的线段的选项。是否可以使用Highcharts进行此操作?如果没有,这个用例有更好的替代方案吗?下面是我当前必须渲染网络图的代码 eventWorkflowGraph = Highcharts.chart('graph-canvas', { chart: { type: 'networkgraph', spaci

这将按如下方式呈现网络图:
根据评论-以下是如何呈现networkgraph系列中链接末尾箭头的答案 演示:
(功能(H){
H.wrap(H.seriesTypes.networkgraph.prototype.pointClass.prototype,'getLinkPath',函数(p){
var left=this.toNode,
右=this.fromNode;
变量角度=Math.atan((left.plotX-right.plotX)/
(left.plotY-right.plotY));
如果(角度){
设路径=['M',left.plotX,left.plotY,right.plotX,right.plotY],
最后一点=左,
nextLastPoint=右,
点半径=45,
箭头长度=20,
箭头宽度=10;
if(left.plotY
我在代码方面取得了一些进展-请看一看:对于这个演示,我也设法做到了,包括radius值:不幸的是,当前的networkgraph实现没有提供节点之间的双链接。您可以在Highcharts用户语音频道:或Highcharts GitHub问题频道上报告此想法:我发布了答案,可能对其他将面临相同问题的用户有用。谢谢
