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。

2.叠加流光效果

多条曲线叠加,但注意,需要监听legendselectchanged事件,

option = {

    show: true,
  },
  grid: {

    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 = [];
        option.series[3].data = [];
      }
      if (!selectArr[1]) {
        option.series[4].data = [];
