echarts散点图

一、类似散点图折线图不展示折线

option = {grid: {left: '10',right: '20',top: '35',bottom: '15',containLabel: true},tooltip: {show: true,trigger: 'item',backgroundColor: "rgba(0,0,0,0)", // 提示框浮层的背景颜色。formatter: function (params) {var html = ` <div style="background:#fff;width: 100px;box-shadow: 0px 3px 6px 1px rgba(0,0,0,0.2);border-radius: 4px;padding:8px;"><divstyle="font-family: Source Han Sans CN, Source Han Sans CN;font-weight: 500;font-size: 14px;color: #000000;">${params.name}</div><div style="display: flex; align-items: center"><divstyle="width: 8px;height: 8px;background: ${params.color};border-radius: 50%;margin-right: 5px;"></div><divstyle="font-family: Source Han Sans CN, Source Han Sans CN;font-weight: 400;font-size: 12px;color: ${params.color};">${params.seriesName}</div></div><divstyle="display: flex;width: 100px;align-items: center;justify-content: space-between;font-family: Source Han Sans CN, Source Han Sans CN;font-weight: 400;font-size: 12px;color: #333333;"><div>百分比</div><div>${params.data.value}%</div></div><divstyle="display: flex;align-items: center;justify-content: space-between;font-family: Source Han Sans CN, Source Han Sans CN;font-weight: 400;font-size: 12px;color: #333333;"><div>指标数</div><div>${params.data.targetNum}</div></div><divstyle="display: flex;align-items: center;justify-content: space-between;font-family: Source Han Sans CN, Source Han Sans CN;font-weight: 400;font-size: 12px;color: #333333;"><div>完成数</div><div>${params.data.finishNum}</div></div></div>`return html;}},legend: {show: true,right: 10,top: '0',y: '0',icon: 'stack',itemWidth: 16,itemHeight: 10,textStyle: {color: '#333333'},data: ['x1', 'x2', 'x3', 'x4', 'x5']},xAxis: [{type: 'category',axisLabel: {color: "#333333"},axisLine: {show: true,lineStyle: {color: '#E1E3E9',width: 2}},axisTick: {show: false,},splitLine: {show: false,lineStyle: {color: '#E1E3E9'}},data: ['x1', 'x2', 'x3', 'x4', 'x5']}],yAxis: [{type: 'value',name: '(%)',min: 0,interval: 50, // 指定刻度间隔nameTextStyle: {  // y轴name的样式调整color: '#999',fontSize: 14,padding: [0, 20, 0, 0] // 加上padding可以调整其位置},axisLabel: {textStyle: {color: "#333333",},formatter: function (value) {if (value === 100) {return `{a|${value}}`;} else {return value;}},rich: {a: {color: 'red' // 这里设置为你想要的颜色}}},axisLine: {show: false,},axisTick: {show: false,},splitLine: {show: true,lineStyle: {color: '#E1E3E9',type: 'dashed',}}}],series: [{name: 'x1',type: 'line',symbol: 'circle',symbolSize: 10,symbolOffset: [-40, 0],itemStyle: {normal: {color: '#9B83DF',lineStyle: {color: "#9B83DF",width: 0,},}},markLine: {symbol: "none",silent: true, //鼠标悬停事件  true没有，false有label: {show: true,position: "end", //将警示值放在哪个位置，三个值“start”,"middle","end"  开始  中点 结束formatter: "",},data: [{type: 'line',triggerEvent: false, //坐标轴的标签是否响应和触发鼠标事件yAxis: "100",lineStyle: {color: "#D9001B",},axisPointer: {type: 'none'}},],},data: [{value:"180",targetNum:"10",finishNum:"8"},{finishNum: "19",value: "120.76",targetNum: "25"},{finishNum: "129",value: "20",targetNum: "225"},{finishNum: "19",value: "30.55",targetNum: "125"},{finishNum: "129",value: "40.16",targetNum: "225"},]},{name: 'x2',type: 'line',symbol: 'circle',symbolSize: 10,symbolOffset: [-20, 0],itemStyle: {normal: {color: '#2977FF',lineStyle: {color: "#2977FF",width: 0},}},data: [ {value:"120",targetNum:"10",finishNum:"8"},{finishNum: "19",value: "10.76",targetNum: "25"},{finishNum: "129",value: "99.12",targetNum: "225"},{finishNum: "19",value: "120.55",targetNum: "125"},{finishNum: "129",value: "60.16",targetNum: "225"},]},{name: 'x3',type: 'line',symbol: 'circle',symbolSize: 10,itemStyle: {normal: {color: '#29A2FF',lineStyle: {color: "#29A2FF",width: 0},}},data: [{value:"123.3",targetNum:"10",finishNum:"8"},{finishNum: "19",value: "120.76",targetNum: "25"},{finishNum: "129",value: "43.55",targetNum: "225"},{finishNum: "19",value: "22.56",targetNum: "125"},{finishNum: "129",value: "140.16",targetNum: "225"},]},{name: 'x4',type: 'line',symbol: 'circle',symbolSize: 10,symbolOffset: [20, 0],itemStyle: {normal: {color: '#42CDC8',lineStyle: {color: "#42CDC8",width: 0,},}},data: [{value:"13.3",targetNum:"10",finishNum:"8"},{finishNum: "19",value: "180.76",targetNum: "25"},{finishNum: "129",value: "413.55",targetNum: "225"},{finishNum: "19",value: "122.56",targetNum: "125"},{finishNum: "129",value: "99.16",targetNum: "225"},]},{name: 'x5',type: 'line',symbol: 'circle',symbolSize: 10,symbolOffset: [40, 0],itemStyle: {normal: {color: '#0AAE52',lineStyle: {color: "#0AAE52",width: 0,},}},data: [{value:"49.3",targetNum:"10",finishNum:"8"},{finishNum: "19",value: "230.76",targetNum: "25"},{finishNum: "129",value: "98.55",targetNum: "225"},{finishNum: "19",value: "72.56",targetNum: "125"},{finishNum: "129",value: "120.16",targetNum: "225"},]},]}

二、常见饼图

let title = '总量';
let color = ['#FEBA26', '#9B83DF', '#2977FF'];
let echartData = [{name: "aa",value: 10},{name: "bb",value: 20},{name: "cc",value:11},];
let total = echartData.reduce((a, b) => {return a + b.value * 1
}, 0);
option = {color: color,tooltip: {show: true,trigger: 'item',},title: [{text: '{val|' + total + '}\n' + '{name|' + title + '}',top: '120',left: 'center',textStyle: {rich: {name: {fontSize: 12,fontWeight: '400',color: '#000',padding: [10, 0]},val: {fontSize: 28,fontWeight: 'bold',color: '#000000',}}}}],series: [{type: 'pie',radius: ['50%', '65%'],center: ['50%', '50%'],data: echartData,hoverAnimation: true,itemStyle: {normal: {borderColor: "#fff",borderWidth: 5}},labelLine: {show: false,},label: {show: false,},},{color: ['#E2EDFF'],type: 'pie',hoverAnimation: false, //鼠标移入变大center: ['50%', '50%'],radius: ['45%', '46%'],label: {normal: {show: false}},data: [{value: 0,name: '',}]},],};

三、堆叠柱状图展示合计 title增加背景图点击图例更新总计计算

var barTitle = "我是表头背景图代码注释了";
var dataJP = [123,33,33];
var dataJJ = [123,33,33];
var dataJYX = [123,33,33];
var sumArrays = dataJP.map((value, index) => value + dataJJ[index] + dataJYX[index]);
option = {title: {show: true,x: '30',text: '{A| ' + barTitle + '}',//主标题文字样式textStyle: {rich: {A: {//设置背景图片，可以设置width和height，不设置时宽高自适应backgroundColor: {//   image: require('@/assets/imgs/evaluation/barTitleBack.png'),},color: '#333',padding: [10, 12],fontSize: 14,},},}},grid: {top: 70,right: 20,left: 40,bottom: 20,containLabel: true,},tooltip: {trigger: "axis",axisPointer: {type: "shadow",textStyle: {color: "#fff"}},formatter: function (params) {let color = ['#2977FF', '#9B83DF', '#FEBA26'];let tooltipText = ` <span>${params[0].axisValue}</span><br/>`;// 遍历数据点并构建 tooltip 内容params.forEach((item, index) => {// 只显示非合计的数据if (item.seriesName !== '合计') {tooltipText += `<spanstyle="display: inline-block;margin-right: 5px;border-radius: 10px;width: 10px;height: 10px;background-color: ${item.seriesName == 'aa' ? '#2977FF' : item.seriesName == 'bb' ? '#9B83DF' : item.seriesName == 'cc' ? '#FEBA26' : ''};"></span>${item.seriesName}: ${item.value}<br/>`;}});return tooltipText;}},legend: {icon: 'stack',right: 10,top: "0",itemWidth: 16,itemHeight: 10,data: ["aa", "bb", "cc"]},xAxis: {data: ["aa", "bb", "cc"],type: 'category',axisLabel: {color: "#333333"},axisLine: {show: true,lineStyle: {color: '#E1E3E9',width: 2}},axisTick: {show: false,},splitLine: {show: false,},},yAxis: {splitLine: {show: true,lineStyle: {color: '#E1E3E9',type: 'dashed'}},axisLine: {show: false,},axisLabel: {textStyle: {color: "#000" //坐标值得具体的颜色}},axisTick: {show: false,}},series: [{name: 'aa',type: "bar",barWidth: "15px",stack: 'total',data: dataJP,itemStyle: {normal: {color: "#2977FF"}}},{name: 'bb',type: "bar",barWidth: "15px",stack: 'total',data: dataJJ,itemStyle: {normal: {color: "#9B83DF"}}},{name: 'cc',type: "bar",barWidth: "15px",stack: 'total',data: dataJYX,itemStyle: {normal: {color: "#FEBA26"}}},{name: '合计',type: 'bar',stack: 'total',data: sumArrays,color: 'transparent',label: {position: 'insideBottom',show: true,color: '#666666',}}]};
