Highcharts 应使用highchart在不更改现有节点位置的情况下添加新节点

Highcharts.chart（'容器'{ 图表：{ 键入：“网络图”，

我在添加或修改节点时使用网络图，现有节点位置变化很大。如果我希望在不改变位置的情况下进行更改，我该怎么办

代码：

---

因此，您可以让我知道如何实现这一点。

您可以将

最大迭代次数

属性归零，并在

重画

事件中为新点定义自定义位置：

chart: {
    ...,
    events: {
        load: function() {
            var chart = this;

            setTimeout(function() {
                chart.series[0].addPoint(['G', 'Z'], true);
            }, 2000);
        },
        redraw: function() {
            var newNode = this.series[0].nodes[7];

            newNode.plotX = 100;
            newNode.plotY = 100;
        }
    }
}
