常用的echarts图表的实现代码
本篇文章给大家带来的内容是关于常用的echarts图表的实现代码,有一定的参考价值,有需要的朋友可以参考一下,希望对你有所帮助。
本文代码基于ehcarts4.0开发
饼图
// 饼图配置项 var option = { series: [ { name:'风险预警占比', type: 'pie', radius: ['25%', '40%'], center: ['50%', '50%'], roseType: false, data: [ { value: 40, name: '红色预警' }, { value: 30, name: '橙色预警' }, { value: 10, name: '黄色预警' }, { value: 50, name: '蓝色预警' } ], label: { fontSize: 12, color:'#545454', formatter: function (param) { return param.name + '(' + Math.round(param.percent) + '%' + ')' + '' + param.value + '个'; } }, labelLine: { smooth: false, lineStyle: { width: 2 } }, itemStyle: { color:function(params){ switch (params.name) { case '红色预警': return '#D70002'; case '橙色预警': return '#FF9309'; case '黄色预警': return '#FFFB09'; case '蓝色预警': return '#035EF7'; default: break; } } }, } ] }
堆叠柱状图
//堆叠柱状图配置项 var option = { backgroundColor: '#fff', tooltip: { trigger: 'axis', axisPointer: { type: 'shadow' } }, legend: { bottom: '10', itemGap: 30, data: ['一级', '二级', '三级', '四级'] }, grid: { //图表的位置 top: 30, left: 10, right: 80, bottom: 60, containLabel: true }, dataZoom: [ { type: 'inside' }, { type: 'slider', start: 0, bottom: 40, height: '15px', fillerColor:'rgba(202,223,255,.8)', borderColor:'#b6d2fc', handleStyle:{ color:'#b6d2fc' }, dataBackground:{ lineStyle:{ color:'#b6d2fc' }, areaStyle:{ color:'rgba(202,223,255,.8)' } } } ], yAxis: [ { type: 'value', name: '备案个数', nameTextStyle: { fontSize: 12, fontWeight: 'bold', color: '#454545' }, splitLine: { show: false }, axisLine: { lineStyle: { color: '#B3B3B3' } }, axisLabel: { color: '#454545' } } ], xAxis: [ { type: 'category', name: '区县名称', nameTextStyle: { fontSize: 12, fontWeight: 'bold', color: '#454545' }, axisLine: { lineStyle: { color: '#B3B3B3' } }, axisLabel: { color: '#454545' }, data: ['鼓楼区','玄武区','秦淮区'] } ], series: [ { name: '一级', type: 'bar', stack: '总量', barWidth: '10px', itemStyle:{ color:'#D70002' }, data: [2,4,6] }, { name: '二级', type: 'bar', stack: '总量', barWidth: '10px', data: [2,4,1] }, { name: '三级', type: 'bar', stack: '总量', barWidth: '10px', itemStyle:{ color:'#FFFB09' }, data: [1,5,7] }, { name: '四级', type: 'bar', stack: '总量', barWidth: '10px', itemStyle:{ color:'#FF9309' }, data: [1] } ] }
渐变柱状图
//配置项var option = { backgroundColor: '#fff', color: [ new echarts.graphic.LinearGradient( 0, 0, 0, 1, [ { offset: 0, color: '#23E9EE' }, { offset: 1, color: '#0460F7' } ] ) ], tooltip: { trigger: 'axis', axisPointer: { type: 'shadow' } }, legend: { bottom: '10', itemGap: 30, data: ['一级', '二级', '三级', '四级'] }, grid: { //图表的位置 top: 30, left: 10, right: 80, bottom: 60, containLabel: true }, dataZoom: [ { type: 'inside' }, { type: 'slider', start: 0, bottom: 40, height: '15px', fillerColor:'rgba(202,223,255,.8)', borderColor:'#b6d2fc', handleStyle:{ color:'#b6d2fc' }, dataBackground:{ lineStyle:{ color:'#b6d2fc' }, areaStyle:{ color:'rgba(202,223,255,.8)' } } } ], yAxis: [ { type: 'value', name: '备案个数', nameTextStyle: { fontSize: 12, fontWeight: 'bold', color: '#454545' }, splitLine: { show: false }, axisLine: { lineStyle: { color: '#B3B3B3' } }, axisLabel: { color: '#454545' } } ], xAxis: [ { type: 'category', name: '区县名称', nameTextStyle: { fontSize: 12, fontWeight: 'bold', color: '#454545' }, axisLine: { lineStyle: { color: '#B3B3B3' } }, axisLabel: { color: '#454545' }, data: ['鼓楼区','玄武区','秦淮区'] } ], series: [ { name: '报警', type: 'bar', stack: '总量', barWidth: '10px', data: [1,2,4] } ] };
线图
//线图配置项var option = { tooltip: { trigger: 'axis' }, color: [ new echarts.graphic.LinearGradient( 0, 0, 0, 1, [ {offset: 0, color: '#23E9EE'}, {offset: 1, color: '#0460F7'} ] ) ], grid: { top: 30, left: 10, right: 30, bottom: 50, containLabel: true }, dataZoom: [ { type: 'inside' }, { type: 'slider', start: 0, bottom: 30, height: '15px', fillerColor:'rgba(202,223,255,.8)', borderColor:'#b6d2fc', handleStyle:{ color:'#b6d2fc' }, dataBackground:{ lineStyle:{ color:'#b6d2fc' }, areaStyle:{ color:'rgba(202,223,255,.8)' } } } ], yAxis: [ { type: 'value', splitLine: { show: false }, axisLine: { lineStyle: { color: '#B3B3B3' } }, axisLabel: { color: '#454545' } } ], xAxis: { type: 'category', boundaryGap:false, axisLine: { lineStyle: { color: '#B3B3B3' } }, axisLabel: { color: '#454545' }, data: ['周一', '周二', '周三', '周四', '周五', '周六', '周日'] }, series: [ { name: '报警个数', type: 'line', symbol: 'emptyCircle', symbolSize: 2, showSymbol: false, smooth: true, areaStyle: { color: new echarts.graphic.LinearGradient( 0, 0, 0, 1, [ {offset: 0, color: 'rgba(35,233,238,.4)'}, {offset: 1, color: 'rgba(4,96,247,.4)'} ] ) }, lineStyle: { width: 1, color: '#59cef5' }, itemStyle: { borderColor: '#59cef5', borderWidth: 2 }, data:[2,4,3,2,1,4,2] } ] }
创建实例
var chart = echarts.init(document.getElementById('chartBox'));
设置图表实例的配置项
设置图表实例的配置项以及数据,万能接口,所有参数和数据的修改都可以通过setOption完成,ECharts 会合并新的参数和数据,然后刷新图表chart.setOption(option);
