[GitHub] [incubator-echarts] zpf96126 opened a new issue #12545: 动态数据 时间坐标轴，以秒为最小单位时，每分钟的前10秒数据未被绘制
zpf96126 opened a new issue #12545:
URL: https://github.com/apache/incubator-echarts/issues/12545
### Version
4.7.0
### Reproduction link
[https://www.echartsjs.com/examples/zh/editor.html?c=dynamic-data2](https://www.echartsjs.com/examples/zh/editor.html?c=dynamic-data2)
### Steps to reproduce
将随机数值函数修改为
function randomData() {
now = new Date();
value = value Math.random() * 21 - 10;
return {
name: now.toString(),
value: [
[now.getFullYear(), now.getMonth() 1, now.getDate()].join('/') " " [now.getHours(), now.getMinutes(), now.getSeconds()].join(':'),
Math.round(value)
]
};
}
将格式化日期修改为
tooltip: {
trigger: 'axis',
formatter: function (params) {
params = params[0];
var date = new Date(params.name);
return date.getDate() '/' (date.getMonth() 1) '/' date.getFullYear() ' ' date.getHours() ':' date.getMinutes() ':' date.getSeconds() ' : ' params.value[1];
},
axisPointer: {
animation: false
}
},
### What is expected?
能够按秒显示动态数据折线
### What is actually happening?
每分钟的前10秒会卡住，然后不绘制这段时间内的折线

`randomData` 里使用的是 new Date()
所得到的值是不确定的值。所以并不确定形成的数据在哪个时间点上。

我把function randomData() {
now = new Date();
value = value Math.random() * 21 - 10;
return {
name: now.toString(),
value: [
[now.getFullYear(), now.getMonth() 1, now.getDate()].join('/') +" "+ [now.getHours(), now.getMinutes(), now.getSeconds()].join(':'),
Math.round(value)
]
};
}
改成
function randomData() {
now = new Date();
value = value Math.random() * 21 - 10;
var ds;
if (now.getSeconds()< 10) {
ds = "0" + now.getSeconds().toString();
} else {
ds = now.getSeconds().toString();
}
return {
name: now.toString(),
value: [
[now.getFullYear(), now.getMonth() 1, now.getDate()].join('/')+ " "+ [now.getHours(), now.getMinutes(), ds].join(':'),
Math.round(value)
]
};后正常了
}
