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 = {

多条曲线叠加，但注意，需要监听legendselectchanged事件，

},

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 = [];
}

}
myChart.setOption(option);
});
