后端使用django实现，返回的数据可以修改为从数据库获取或其他方式获取，实例里是写死的数据。
urls配置：
url(r‘^outip/chart/$‘, views.charts), url(r‘^outip/getchart/$‘, views.get_chart), url(r‘^outip/getlast/$‘, views.get_last), url(r‘^outip/detail/$‘, views.get_detail_chart),
所有实例浏览器访问的后端方法：charts
@csrf_exempt
def charts(request):
return render_to_response(‘html/chart.html‘)
所有实例使用的html代码：chart.html
<html> <head> <meta charset="utf-8"> <style> </style> <script type="text/javascript" src="/outip/staticfiles/js/jquery-2.1.4.js"></script> <script type="text/javascript" src="/outip/staticfiles/highcharts/js/highcharts.js"></script> <script type="text/javascript" src="/outip/staticfiles/highcharts/js/modules/exporting.js"></script> <script type="text/javascript" src="/outip/staticfiles/js/activechart.js"></script> <!-- <script type="text/javascript" src="/outip/staticfiles/js/chart.js"></script> --> </head> <body> <div id="container" style="min-width:400px;height:400px"></div> <script> </script> </body> </html>
1.实时刷新曲线图（若取消实时刷新，将activechart.js中 chart的events删除即可）：
js代码: activechart.js
$(document).ready(function () {
Highcharts.setOptions({
decimalPoint: ‘.‘, // 小数点号，例如 12.50
thousandsSep: ‘,‘, // 千分号，例如 12,000
global: {
useUTC: false
}
});
function getchart() {
var datax = [];
var datay = [];
$.ajax({
type: "POST",
dataType: "json",
url:‘/outip/getchart/‘,
success: function(result) {
if (result.errno == 0) {
for(var i=0;i<result.data.length;i++) {
datax.push(result.data[i].x)
datay.push(result.data[i].y)
};
start(datax,datay);
//console.log(datax);
//console.log(t);
}else {
alert(‘err‘);
}
}
});
}
function start(datax,datay) {
$(‘#container‘).highcharts({
chart: {
type: ‘spline‘,
animation: Highcharts.svg,
marginRight: 10,
events: {
load: function () {
var series = this.series[0];
setInterval(function () {
$.ajax({
type: "POST",
dataType: "json",
url:‘/outip/getlast/‘,
success: function(result) {
if (result.errno == 0) {
series.addPoint([result.data.x, result.data.y], true, true);
} else {
alert(‘last err‘);
}
}
});
}, 60000);
}
}
},
title: {
text: ‘Total flow‘,
x: -20 //center
},
//subtitle: {
// text: ‘Source:‘,
// x: -20
//},
xAxis: {
categories: datax
//categories: ["2016-10-08 17:11"]
},
yAxis: {
title: {
text: ‘flow/Bytes‘
},
plotLines: [{
value: 0,
width: 1,
color: ‘#808080‘
}]
},
credits:{
enabled:false // 禁用版权信息
},
tooltip: {
valueSuffix: ‘ Bytes‘,
formatter:function(){
//console.log(this);
return this.key+‘<br>‘+Highcharts.numberFormat(this.y,‘2‘,‘.‘,‘,‘)+‘ Bytes‘;
}
},
legend: {
layout: ‘vertical‘,
align: ‘center‘,
verticalAlign: ‘bottom‘,
borderWidth: 0
},
series: [{
name: ‘Flow‘,
data: datay
}]
});
}
getchart();
});
后端方法:
1) 获取初始数据：get_chart
@csrf_exempt
def get_chart(request):
data = [{‘x‘:‘2016-10-08 17:11‘,‘y‘:1},{‘x‘:‘2016-10-08 17:12‘,‘y‘:3},{‘x‘:‘2016-10-08 17:13‘,‘y‘:4},{‘x‘:‘2016-10-08 17:14‘,‘y‘:400},{‘x‘:‘2016-10-08 17:15‘,‘y‘:124},{‘x‘:‘2016-10-08 17:16‘,‘y‘:2444},{‘x‘:‘2016-10-08 17:17‘,‘y‘:23334},{‘x‘:‘2016-10-08 17:18‘,‘y‘:40}]
return HttpResponse(json.dumps({‘errno‘:0,‘data‘:data}))
2）获取最新的一个数据：get_last
@csrf_exempt
def get_last(request):
data = {‘x‘:‘2016-10-08 17:19‘,‘y‘:100}
return HttpResponse(json.dumps({‘errno‘:0,‘data‘:data}))
2.基础柱状图
js代码：activechart.js（datay每个元素中要有name和data两个key,且名字不能改，data的值为一个数组；若将plotOptions.column.stacking属性加上，则成为堆叠柱状图）
function getchart() {
var datax;
var datay;
$.ajax({
type: "POST",
dataType: "json",
url:‘/outip/detail/‘,
success: function(result) {
if (result.errno == 0) {
datax = result.data.time
datay = result.data.value
start(datax,datay);
//console.log(datay);
//console.log(t);
}else {
alert(‘err‘);
}
}
});
}
function start(datax,datay) {
$(‘#container‘).highcharts({
chart: {
type: ‘column‘
},
title: {
text: ‘Detail flow‘,
x: -20 //center
},
credits:{
enabled:false // 禁用版权信息
},
//subtitle: {
// text: ‘Source:‘,
// x: -20
//},
xAxis: {
categories: datax
//categories: ["2016-10-08 17:11"]
},
yAxis: {
title: {
text: ‘flow/Bytes‘
},
plotLines: [{
value: 0,
width: 1,
color: ‘#808080‘
}]
},
tooltip: {
formatter: function () {
return this.x + ‘ Total: ‘ + Highcharts.numberFormat(this.point.stackTotal,‘2‘,‘.‘,‘,‘) +
‘ Bytes<br/><b>‘ + this.series.name + ‘: ‘ + Highcharts.numberFormat(this.y,‘2‘,‘.‘,‘,‘) + ‘ Bytes</b>‘;
},
valueSuffix: ‘ Bytes‘
},
plotOptions: {
column: {
pointPadding: 0.2,
borderWidth: 0,
//stacking: ‘normal‘,
dataLabels: {
enabled: true,
color: (Highcharts.theme && Highcharts.theme.dataLabelsColor) || ‘black‘,
style: {
textShadow: ‘0 0 3px black‘
}
}
}
},
/*legend: {
layout: ‘vertical‘,
align: ‘right‘,
verticalAlign: ‘middle‘,
borderWidth: 0
},*/
//series: [{‘name‘:‘1‘,‘data‘:[1]},{‘name‘:‘2‘,‘data‘:[3]}] /*[{
series: datay /*[{
name: ‘Flow‘,
data: datay
}]*/
});
}
getchart();
后端方法：get_detail_chart
@csrf_exempt
def get_detail_chart(request):
data = {‘time‘:[‘2016-10-08 17:19‘],‘value‘:[{‘name‘:‘x0‘,‘data‘:[70]},{‘name‘:‘x1‘,‘data‘:[60]},{‘name‘:‘x2‘,‘data‘:[21]},{‘name‘:‘x3‘,‘data‘:[31]},{‘name‘:‘x4‘,‘data‘:[50]},{‘name‘:‘x5‘,‘data‘:[40]},{‘name‘:‘x6‘,‘data‘:[22]},{‘name‘:‘x7‘,‘data‘:[1]},{‘name‘:‘x8‘,‘data‘:[20]},{‘name‘:‘x9‘,‘data‘:[10]},{‘name‘:‘x10‘,‘data‘:[30]}]}
return HttpResponse(json.dumps({‘errno‘:0,‘data‘:data}))
3.堆叠柱状图
js代码：activechart.js
function getchart() {
var datax;
var datay;
$.ajax({

}
}
});
}

}]
},
tooltip: {
