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="cdnjs.cloudflare/ajax/libs/jquery/2.2.1/jquery.min.js"></script> <script src="code.highcharts/highcharts.js"></script> <script src="code.highcharts/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 }] });
