HighCharts是开源的Web图表js组件，与D3.js一样，经常用于数据可视化。HighCharts图表类型丰富，功能非常强大，是很好的数据可视化解决方案，其官方网站为：http://www.hcharts.cn/，感兴趣的读者可以自行去下载HighCharts并按照给出的Example尝试着开发，基本上按照示例中的例子，把数据部分替换成自己想要展示的数据就可以了，非常容易上手。本篇博客将结合ASP.NET MVC和HighCharts开发统计图表功能，为简单起见，这里只演示三个最基本、最常用的图表类型（柱状图、饼图）。
一、横向柱状图
前端cshtml代码：
@{
Layout = null;
}
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>退休单位统计</title>
<script src='@Url.Content("~/Scripts/jquery-1.7.1.js")'></script>
<script src='@Url.Content("~/Scripts/hightcharts/highcharts.js")'></script>
<script src='@Url.Content("~/Scripts/hightcharts/exporting.js")'></script>
<script src='@Url.Content("~/Scripts/hightcharts/highcharts-zh_CN.js")'></script>
</head>
<body>
<div id="container" style="min-width: 400px; height: 400px">
</div>
<script type="text/javascript">
$(function () {
$.ajax({
url: '@Url.Action("GetTXDW", "TJTB")',
type: 'get',
success: function (result) {
var name = result.split(';')[0];
var data = result.split(';')[1];
var nname = eval('(' + name + ')');
var ddata = eval('(' + data + ')');
$('#container').highcharts({
chart: {
type: 'bar'
},
title: {
text: '退休人数最多的十个单位'
},
subtitle: {
text: ''
},
xAxis: {
categories: nname,
// [
// '*职业',
// 'xxx有限公司',
// 'xxx工程总公司',
// 'xxx有限公司',
// 'xxx总公司',
// 'xxx有限公司',
// 'xxx有限公司',
// 'xxx有限公司',
// 'xxx厂',
// 'xxx有限责任公司'
// ],
title: {
text: null
}
},
yAxis: {
min: 0,
title: {
text: '人数',
align: 'high'
},
labels: {
overflow: 'justify'
}
},
tooltip: {
valueSuffix: '人'
},
plotOptions: {
bar: {
dataLabels: {
enabled: true,
allowOverlap: true
}
}
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'top',
x: -40,
y: 100,
floating: true,
borderWidth: 1,
backgroundColor: ((Highcharts.theme && Highcharts.theme.legendBackgroundColor) || '#FFFFFF'),
shadow: true
},
credits: {
enabled: false
},
series:
[{
name: '人数',
data: ddata
//data: [23926, 2328, 1828, 1816, 1485, 1464, 1408, 1164, 1124, 1124]
}
]
});
}
});
})
</script>
</body>
</html>
控制器cs代码：
/// <summary>
/// 退休单位统计
/// </summary>
/// <returns></returns>
[HttpGet]
public string GetTXDW()
{
string result1 = string.Empty;
string result2 = string.Empty;
string sql = @"with a as(select rownum rn,t.* from(
select gzdw,count(gzdw) xl from T_RYXX
group by gzdw
order by xl desc) t)
select gzdw,xl from a where a.rn>=1 and a.rn<=10"; result1 += "[";
result2 += "[";
DataSet ds = OracleHelper.Query(sql);
for (int i = ; i < ds.Tables[].Rows.Count; i++)
{
result1 += "'" + ds.Tables[].Rows[i]["GZDW"].ToString() + "'";
result2 += ds.Tables[].Rows[i]["XL"].ToString();
if (i != ds.Tables[].Rows.Count - )
{
result1 += ",";
result2 += ",";
}
}
result1 += "]";
result2 += "]";
return result1 + ";" + result2;
}
二、饼图
前端cshtml代码：
@{
Layout = null;
}
<!DOCTYPE html>

</head>
<body>
<div id="container" style="min-width: 400px; height: 400px">
</div>
<script type="text/javascript">
$(function () {
$.ajax({
url: '@Url.Action("GetXBTJ", "TJTB")',
type: 'get',
success: function (result) {
var data = eval('(' + result + ')');
$('#container').highcharts({

},

}
}
}
},
series: [{

data: data
}]
});
}
});
});
</script>
</body>
</html>
控制器cs代码：
/// <summary>

/// </summary>
/// <returns></returns>
[HttpGet]
public string GetXBTJ()
{

return result;
}
