ECharts 雷达图怎么在类目值下面显示数值
需要实现的效果:
官网里面的demo显示数值,都是在拐点处:
【解决】
1、只显示类目
<div id="mychart" style="width:300px;height:300px;margin:0 auto;"></div> <script> var arr1 = [60,73,85,40,60]; var arr2 = [23,90,23,32,67]; var mychart = echarts.init(document.getElementById('mychart')); var option = { radar: [ { indicator: [ {text: '品牌', max: 100}, {text: '内容', max: 100}, {text: '可用性', max: 100}, {text: '功能', max: 100}, {text: '屏幕', max: 100} ], center: ['50%','54%'],//调整雷达图的位置 radius: 80,//半径,可放大放小雷达图 axisLine: {//坐标轴线相关设置 show: true, lineStyle: { color: 'red' } }, splitLine : { show : true, lineStyle : { width : 1, color : 'red' // 图表背景网格线的颜色 } }, splitArea: { show: false, }, name: { rich: { a: { color: 'red', lineHeight: 20 }, }, formatter: (a)=>{ return `{a|${a}}` } } }, ], series: [ { type: 'radar', symbol: 'none',//去掉拐点的圈 data: [ { value: arr1, name: '某软件', areaStyle: { normal: { color: 'blue' } }, lineStyle: { color:"rgba(255,255,255,0)" }, },{ value: arr2, name:'jja', areaStyle: { normal: { color: 'red' // 图表中各个图区域的颜色 } }, lineStyle: { color:"rgba(255,255,255,0)" // 图表中各个图区域的边框线颜色 }, } ] }, ] }; mychart.setOption(option); </script>
实现效果:
2、实现最简单的数值在类目下
<div id="mychart" style="width:300px;height:300px;margin:0 auto;"></div> <script> var arr1 = [60,73,85,40,60]; var arr2 = [23,90,23,32,67]; var mychart = echarts.init(document.getElementById('mychart')); var option = { radar: [ { indicator: [ {text: '品牌', max: 100}, {text: '内容', max: 100}, {text: '可用性', max: 100}, {text: '功能', max: 100}, {text: '屏幕', max: 100} ], center: ['50%','54%'],//调整雷达图的位置 radius: 80,//半径,可放大放小雷达图 axisLine: {//坐标轴线相关设置 show: true, lineStyle: { color: 'red' } }, splitLine : { show : true, lineStyle : { width : 1, color : 'red' // 图表背景网格线的颜色 } }, splitArea: { show: false, }, name: { rich: { a: { color: 'red', lineHeight: 20 }, b: { color: '#fff', align: 'center', backgroundColor: '#666', padding: 2, borderRadius: 4 } }, formatter: (a,b)=>{ return `{a|${a}}\n{b|999}` } } }, ], series: [ { type: 'radar', symbol: 'none',//去掉拐点的圈 data: [ { value: arr1, name: '某软件', areaStyle: { normal: { color: 'blue' } }, lineStyle: { color:"rgba(255,255,255,0)" }, },{ value: arr2, name:'jja', areaStyle: { normal: { color: 'red' // 图表中各个图区域的颜色 } }, lineStyle: { color:"rgba(255,255,255,0)" // 图表中各个图区域的边框线颜色 }, } ] }, ] }; mychart.setOption(option); </script>
3、实现最终效果
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width,initial-scale=1.0"> <title></title> <script src="js/jquery.min.js"></script> <script src="js/echarts.js"></script> </head> <body> <div id="mychart" style="width:300px;height:300px;margin:0 auto;"></div> <script> var arr1 = [60,73,85,40,60]; var arr2 = [23,90,23,32,67]; var mychart = echarts.init(document.getElementById('mychart')); var option = { radar: [ { indicator: [ {text: '品牌', max: 100}, {text: '内容', max: 100}, {text: '可用性', max: 100}, {text: '功能', max: 100}, {text: '屏幕', max: 100} ], center: ['50%','54%'],//调整雷达图的位置 radius: 80,//半径,可放大放小雷达图 axisLine: {//坐标轴线相关设置 show: true, lineStyle: { color: 'red' } }, splitLine : { show : true, lineStyle : { width : 1, color : 'red' // 图表背景网格线的颜色 } }, splitArea: { show: false, }, }, ], series: [ { type: 'radar', symbol: 'none',//去掉拐点的圈 data: [ { value: arr1, name: '某软件', areaStyle: { normal: { color: 'blue' } }, lineStyle: { color:"rgba(255,255,255,0)" }, },{ value: arr2, name:'jja', areaStyle: { normal: { color: 'red' // 图表中各个图区域的颜色 } }, lineStyle: { color:"rgba(255,255,255,0)" // 图表中各个图区域的边框线颜色 }, } ] }, ] }; mychart.setOption(option); var i = -1; mychart.setOption({ radar: [ { name: { rich: { a: { color: 'red', lineHeight: 20 }, b: { color: '#fff', align: 'center', backgroundColor: '#666', padding: 2, borderRadius: 4 } }, formatter: (a,b)=>{ i++; return `{a|${a}}\n{b|${arr1[i]}}` } } } ] }) </script> </body> </html>
