下面这段代码直接粘贴到echarts官网就能执行，但我使用本地的vue执行后，缩放变得卡顿，但是官网上很流畅
var base = +new Date(1968, 9, 3);
var oneDay = 24 * 3600 * 1000;
var date = [];
var data = new Array(4);
data[0] = [Math.random() * 300];
for (var i = 0; i < data.length; i++) {
data[i] = [data[0].length];
}
for (var i = 1; i < 20000; i++) {
var now = new Date((base += oneDay));
date.push(
[now.getFullYear(), now.getMonth() + 1, now.getDate()].join("/")
);
data[0].push(Math.round((Math.random() - 0.5) * 20 + data[0][i - 1]));
}
for (var j = 1; j < data.length; j++) {
for (var i = 1; i < 20000; i++) {
data[j].push(Math.round((Math.random() - 0.5) * 20 + data[j][i - 1]));
