1.通过dataZoom实现柱状图动态前移效果
最近做大屏相关需求,产品说需要炫酷一点的效果,于是做了一些echart相关的动效
设置dataZoom当前缩放值,加定时器,实现轮播效果。
示例:
option = { color: ['#1E90FF', '#FFA500'], tooltip: { trigger: 'axis', axisPointer: {} }, grid: { left: 20, right: 20, bottom: 0, containLabel: true }, legend: { data: [ { name: '负载电量', itemStyle: { color: '#FAAD14' } }, { name: '中央空调冷量', itemStyle: { color: '#01E6F5' } } ], textStyle: { color: '#fff' } }, dataZoom: { type: 'inside' }, xAxis: [ { type: 'category', axisLabel: { margin: 20, textStyle: { color: '#fff' } }, data: [ '11:00', '12:00', '13:00', '14:00', '15:00', '16:00', '17:00', '18:00', '19:00', '20:00', '21:00', '22:00', '23:00', '00:00', '01:00', '02:00', '03:00', '04:00', '05:00', '06:00', '07:00', '08:00', '09:00', '10:00' ], axisPointer: { type: 'shadow' } } ], yAxis: [ { type: 'value', name: 'kWh', nameTextStyle: { color: '#fff' }, splitLine: { show: true, lineStyle: { color: 'rgba(255, 255, 255, 0.2)' } }, axisLabel: { margin: 20, textStyle: { color: '#fff' } } }, { type: 'value', name: 'kWh', nameTextStyle: { color: '#fff' }, splitLine: { show: false, lineStyle: { color: 'rgba(255, 255, 255, 0.2)' } }, axisLabel: { margin: 20, textStyle: { color: '#d1e6eb' } } } ], series: [ { name: '负载电量', type: 'bar', yAxisIndex: 0, itemStyle: { color: { x: 0, y: 0, x2: 0, y2: 1, colorStops: [ { offset: 0, color: 'rgba(250,173,20, 1)' }, { offset: 0.5, color: 'rgba(250,173,20, 0.8)' }, { offset: 1, color: 'rgba(250,173,20,0.5)' } ] } }, tooltip: { valueFormatter(value) { if (typeof value === 'number') return value.toFixed(2) + 'kWh'; else return '-'; } }, data: [ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0 ] }, { name: '中央空调冷量', type: 'bar', yAxisIndex: 1, itemStyle: { color: { x: 0, y: 0, x2: 0, y2: 1, colorStops: [ { offset: 0, color: 'rgba(1,230,245, 1)' }, { offset: 0.5, color: 'rgba(1,230,245, 0.8)' }, { offset: 1, color: 'rgba(1,230,245,0.5)' } ] } }, tooltip: { valueFormatter(value) { if (typeof value === 'number') return value.toFixed(2) + 'kWh'; else return '-'; } }, data: [ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.10333333333333333, 0.0, 0.0, 0.0, 3.5133333333333336, 6.2, 6.2, 6.2, 6.2, 6.2, 6.2, 6.2, 6.2, 6.2, 6.2, 2.2733333333333334, 0.0 ] } ], func: (myChart, option) => { let start = 0, end = 7; option.dataZoom.startValue = option.xAxis[0].data[start]; // option.dataZoom.endValue = option.xAxis[0].data[end]; myChart.setOption(option); if (this.electInterval) { clearInterval(this.electInterval); } this.electInterval = setInterval(function () { option.dataZoom.startValue = option.xAxis[0].data[start]; option.dataZoom.endValue = option.xAxis[0].data[end]; myChart.setOption(option); start += 1; end += 1; if (end >= option.xAxis[0].data.length) { end = 7; start = 0; } }, 5000); }, }; option.func(myChart, option)
2.叠加流光效果
多条曲线叠加,但注意,需要监听legendselectchanged事件,
option = { tooltip: { trigger: 'axis', show: true, }, grid: { left: 20, right: 20, bottom: 0, containLabel: true, }, dataZoom: { type: 'inside', }, legend: { textStyle: { color: '#fff', borderColor: '#fff' } }, func: (myChart, option) => { // 修复无图表数据切换bug if (option.series[0].data.length <= 0 && option.series[1].data.length <= 0) { return; } option.series[2].data = option.series[0].data; option.series[3].data = option.series[0].data; option.series[4].data = option.series[1].data; option.series[5].data = option.series[1].data; // setTimeout修复初始加载动效没生效bug setTimeout(() => { myChart.clear(); myChart.setOption(option); }, 100) if (this.loadInterval) { clearInterval(this.loadInterval); } this.loadInterval = setInterval(() => { myChart.clear(); myChart.setOption(option); }, 6000); myChart.on('legendselectchanged', function (params) { let selectArr = Object.values(params.selected); option.series[2].data = option.series[0].data; option.series[3].data = option.series[0].data; option.series[4].data = option.series[1].data; option.series[5].data = option.series[1].data; if (!selectArr[0]) { option.series[2].data = [];
