做GIS或其他内部数据统计项目的应该对FusionCharts也不会太陌生，简单易用已无需多说什么了，只是有时候框架不同，实现起来也稍有差异
引用dll调用FusionCharts类的静态方法RenderChartHTML 返回html绑定在数据控件上更为符合webform；
使用JS代码new FusionCharts对象，调用对象的setDataXML或者setDataURL方法更为符合MVC
1、HTML+JS
class="brush:html;gutter:true;"><!--html--> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title></title> <script src="/Scripts/jquery-1.4.4.min.js" type="text/javascript"></script> <script src="/package/FusionCharts/Charts/FusionCharts.js" type="text/javascript"></script> <script type="text/javascript"> $(function () { initChars(); }) function initChars() { var chart = new FusionCharts("/package/FusionCharts/Charts/2Column3D.swf", "ChartId", "600", "350"); //1、加载字符串 //var dataXml = "<chart rotateYAxisName='0' baseFont='微软雅黑' baseFontSize='12' caption='' yAxisName='水果数量' bgcolor='FFFFFF' bgalpha='100' showValues='1' formatNumberScale='0' showBorder='0'><set label='香蕉' value='12' /><set label='橘子' value='55' /><set label='苹果' value='23' /><set label='人参果' value='20' /></chart>"; //chart.setDataXML(dataXml); //2、加载xml chart.setDataURL("/package/FusionCharts/FruitsData.xml"); chart.render("showData"); } </script> </head> <body> <div id="showData"> </div> </body> </html> <!--xml--> <chart rotateYAxisName='0' baseFont='微软雅黑' baseFontSize='12' caption='' yAxisName='水果数量' bgcolor='FFFFFF' bgalpha='100' showValues='1' formatNumberScale='0' showBorder='0'> <set label='香蕉' value='12' /> <set label='橘子' value='55' /> <set label='苹果' value='23' /> <set label='人参果' value='20' /> </chart>
2、ASP.NET Webform
<!-------------aspx---------------->
<form id="form1" runat="server">
<div>
<table id="tbl" border="0" cellpadding="0" cellspacing="0">
<tr>
<td>
<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="true">
<asp:ListItem Text="柱状图" Value="0"></asp:ListItem>
<asp:ListItem Text="饼状图" Value="1"></asp:ListItem>
</asp:DropDownList>
</td>
</tr>
<tr>
<td>
<asp:Panel ID="Panel1" runat="server">
</asp:Panel>
</td>
</tr>
</table>
</div>
</form>
<!-------------code behind---------------->
protected void Page_Load(object sender, EventArgs e)
{
Panel1.Controls.Clear();
Dictionary<string, int> data = new Dictionary<string, int>() {
{"香蕉",12},
{"橘子",55},
{"苹果",23},
{"人参果",20}
};
Panel1.Controls.Add(ShowNewChart(data, DropDownList1.SelectedValue, "数量"));
}
/// <summary>
/// 绑定图形数据
/// </summary>
/// <param name="dic">数据</param>
/// <param name="Type">图形类型</param>
/// <param name="yAxisName">柱状图显示标题</param>
/// <returns></returns>
private LiteralControl ShowNewChart(Dictionary<string, int> dic, string Type, string yAxisName)
{
StringBuilder sb = new StringBuilder();
sb.Append("<chart rotateYAxisName='0' baseFont='微软雅黑' baseFontSize='12' caption='' xAxisName='' yAxisName='" + yAxisName + "' bgcolor='FFFFFF' bgalpha='100' showValues='1' formatNumberScale='0' showBorder='0'>");
foreach (string key in dic.Keys)
{
sb.AppendFormat("<set label='{0}' value='{1}'/>", key, dic[key]);
}
sb.AppendFormat("</chart>");
string types = "";
if (Type == "1")
{
//饼状图 swf路径
types = "package/FusionCharts/Charts/Pie3D.swf";
}
else if (Type == "0")
{
//柱状图
types = "package/FusionCharts/Charts/2Column3D.swf";
}
return new LiteralControl(FusionCharts.RenderChartHTML(types, "", sb.ToString(), "chart1", "650", "250", false, false));
}
3、ASP.NET MVC
//--------------------------view----------------------------------
<script src="@Url.Content("~/package/FusionCharts/Charts/FusionCharts.js")" type="text/javascript"></script>
<script type="text/javascript">
$(function () {
initChars('@Url.Content("~/package/FusionCharts/Charts/2Column3D.swf")');
BindslMapTypeChange();
})
//初始化图表
function initChars(fusionChartsPath) {
var chart = new FusionCharts(fusionChartsPath, "ChartId", "600", "350");
chart.setDataXML("@(new MvcHtmlString(ViewData.Model))");
chart.render("showData");
}
//绑定图表类型选择按钮事件
function BindslMapTypeChange() {
$('#slMapType').change(function () {
if ($(this).val() == "1") {
initChars('@Url.Content("~/package/FusionCharts/Charts/2Column3D.swf")');
}
else {
initChars('@Url.Content("~/package/FusionCharts/Charts/Pie3D.swf")');
}
})
}
</script>
<table border="0" cellpadding="0" cellspacing="0">
<tr>
<td>
图形类型：<select id="slMapType"><option value="1">柱形图</option>
<option value="2">饼形图</option>
</select>
</td>
</tr>
<tr>
<td id="showData">
</td>
</tr>
</table>
//--------------------------action----------------------------------
public ActionResult Index()
{
Dictionary<string, int> data = new Dictionary<string, int>() {
{"香蕉",12},
{"橘子",55},
{"苹果",23},
{"人参果",20}
};
ViewData.Model = GetChartXml(data, "水果数量");
return View();
}
/// <summary>
/// 绑定图形数据
/// </summary>
/// <param name="dic">数据</param>
/// <param name="Type">图形类型</param>

/// <returns></returns>
private string GetChartXml(Dictionary<string, int> dic, string yAxisName)
{
StringBuilder sb = new StringBuilder();
sb.Append("<chart rotateYAxisName='0' baseFont='微软雅黑' baseFontSize='12' caption='' xAxisName='' yAxisName='" + yAxisName + "' bgcolor='FFFFFF' bgalpha='100' showValues='1' formatNumberScale='0' showBorder='0'>");
foreach (string key in dic.Keys)
{
sb.AppendFormat("<set name='{0}' value='{1}'/>", key, dic[key]);
}
sb.AppendFormat("</chart>");
return sb.ToString();
}
