高图网络网络图 [英] highchart network network-graph

问题描述

我正在使用highchart创建网络图.我需要更改工具提示值.但它不起作用.

I am using highchart to create network-graph. i need to change tooltip value. but its not working.

请检查我的代码

var json = [{
    "key": "1",
    "value": "19122",
    "code": "A"
  }, {
    "key": "19122",
    "value": "623753",
     "code": "B"
  }, {
    "key": "19122",
    "value": "582024",
     "code": "C"
  }],
  data = [];

json.forEach(function(point) {
 data.push([point.key, point.value])
});

Highcharts.chart('container', {

  tooltip: {
    formatter: function() {
     return data.code;
    }
  },

  series: [{
    type: 'networkgraph',
    layoutAlgorithm: {
      enableSimulation: true
    },
     dataLabels: {
            enabled: true,
            linkFormat: ''
        },
    data
  }]

});

<script src="https://code.highcharts.com/highcharts.js"></script>
<script src="https://code.highcharts.com/modules/networkgraph.js"></script>
<div id="container"></div>

当我将鼠标悬停在网络葡萄节点上时，我需要显示代码值.我该怎么做.

when i mouse over the network grape node, i need to show code value. how i do it.

推荐答案

尝试一下:

var json = [{
    "key": "1",
    "value": "19122",
    "code": "A"
  }, {
    "key": "19122",
    "value": "623753",
     "code": "B"
  }, {
    "key": "19122",
    "value": "582024",
     "code": "C"
  }],
  data = [];

json.forEach(function(point) {
 data.push([point.key, point.value])
});

Highcharts.chart('container', {

  tooltip: {
    formatter: function() {
      const codes = json.reduce((acc, cur)=>{
        if(cur.key===this.key||cur.value===this.key) acc.push(cur.code);
        return acc;}, []);
      return codes.join(',');         
    }
  },

  series: [{
    type: 'networkgraph',
    layoutAlgorithm: {
      enableSimulation: true
    },
     dataLabels: {
            enabled: true,
            linkFormat: ''
        },
    data
  }]

});
