微软今天发布了Net Framework 3.5下的 Chart 控件，弥补了.Net平台下缺乏一个十分强力的图表控件。
该图表控件支持多种图表，如饼图，柱状图，曲线图，散点图，雷达图，面积图，股票图等，同时支持Winform和Asp.net。
目前该控件只能用在.Net Framework 3.5上，没有查找到For .Net Framework 2.0的信息。
补：根据stu_acer的反馈，原来该款控件来自dundas.com, For .Net Framework 2.0也有，只是需要付费。

WinForm 和 Asp.net的例子（Samples Environment for Microsoft Chart Controls） –
这个只有英文的，没找到英文的。
如何设置X或者Y轴Label间隔数(默认为自动分配，有时候12个X，只会显示6个的lable)
chart1.ChartAreas[0].AxisX.LabelStyle.Interval = 1;
设置为每隔1个就显示一个Lable。
MSChartTest
在UpdatePanel中使用Charts Controls
Code
<httpHandlers>
<add path="ChartImg.axd" verb="GET,HEAD,POST" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="false"/>
</httpHandlers>
通过webservice来传送图片
Code
[WebMethod]
public byte[] GetChart()
{
Chart chart1 = new Chart();
//Set chart properties
//and dind it to data
//Save chart to memory stream
using (MemoryStream s= new MemoryStream())
{
chart1.Save(s, ChartImageFormat.Png);
return s.ToArray();
}
}
GridView中使用
The most simple way to achieve master detail in grid view is to insert a data source and chart ( and other detail output if you need) in a template field. Use data grid RowDataBound event to sync the data sources. The sample bellow shows territory name in the first column and a pie chart in the second column, data bind to sales.
Code
