由于工作需要，需要统计交易数据的TP50，TP90，TP95，TP99。采用的前端技术是jquery+json+echart。
一、TP定义（谷歌）
Calculating TP is very simple:
1. Sort all times in ascending order: [2s, 10s, 100s, 1000s]
2. find latest item in portion you need to calculate.
2.1 For TP50 it will be ceil(4*0.5) = 2 requests. You need 2nd request.
2.2 For TP90 it will be ceil(4*0.9) = 4. You need 4th request.
3. We get time for the item found above. TP50=10s. TP90=1000s
二、json数据结构
{
"2017-01-01": {
"tp50": {
"cost": 0.628
},
"tp90": {
"cost": 0.655
},
"tp95": {
"cost": 0.796
},
"tp99": {
"cost": 1.907
}
},
"2017-01-02": {
"tp50": {
"cost": 0.614
},
"tp90": {
"cost": 0.645
},
"tp95": {
"cost": 0.784
},
"tp99": {
"cost": 2.224
}
},
"2017-01-03": {
"tp50": {
"cost": 0.615
},
"tp90": {
"cost": 0.651
},
"tp95": {
"cost": 0.808
},
"tp99": {
"cost": 2.745
}
}
}
三、前端页面代码片段

$(document).ready(function() {
$("button").click(function() {

$.getJSON({

data:"startDate="+startDate+"&endDate="+endDate,
success : function(data) {
myChart.setOption({
xAxis : {

},
series : [ {

}
});
});
});
</script>
</head>

<div id="main" style="width: 1200px; height: 400px;"></div>
<script>
var myChart = echarts.init(document.getElementById('main'));
option = {

};
myChart.setOption(option);

四、页面展示
