### Steps to Reproduce
var dom = document.getElementById("container");
var myChart = echarts.init(dom);
var app = {};
var option;
let base = +new Date(1968, 9, 3);
let oneDay = 24 * 3600 * 1000;
let date = [];
let data = [Math.random() * 300];
for (let i = 1; i < 40000; i++) {
var now = new Date((base += oneDay));
date.push([i].join('/'));
data.push(Math.round((Math.random() - 0.5) * 20 + data[i - 1]));
}
option = {
animationDuration:30000,
tooltip: {
trigger: 'axis',
position: function (pt) {
return [pt[0], '10%'];
}
},
title: {
left: 'center',
text: 'line Chart (400w data)'
},
toolbox: {
feature: {
dataZoom: {
yAxisIndex: 'none'
},
restore: {},
saveAsImage: {}
}
},
xAxis: {
type: 'category',
boundaryGap: false,
data: date
},
yAxis: {
type: 'value',
boundaryGap: [0, '100%']
},
dataZoom: [
{
type: 'inside',
start: 0,
end: 1
},
{
start: 0,
end: 1000
}
],
series: [
{
name: 'Fake Data',
type: 'line',
symbol: 'none',
sampling: 'lttb',
itemStyle: {
color: 'rgb(255, 70, 131)'
},
data: data
}
]
};
if (option && typeof option === 'object') {
myChart.setOption(option);
}
### Current Behavior
echarts line chart
如果数据量超过2000个（如4000），animtionDuration设置后，动画播放不能正常运行，而是直接显示所有数据
打开devTool后才能正常播放，400w个也行
### Expected Behavior
echarts line chart 如果数据量超过2000个（如4000），animtionDuration设置后，动画播放能正常运行
### Environment
```markdown
