求：vs2010 c# 中的Chart控件的教程和源代码

VS2010 集成了Chart控件，但不会使用呢，比如如何设置样式：饼图、折线图等等，有谁有教程可以看看吗？最好要有源代码。谢谢
坐标的区间用哪个属性？

没有什么好的详细教程，给你简单点的，
简单示例，
<asp:Chart ID="Chart1" runat="server" Height="400px" Width="500px">
<Series>
<asp:Series Name="Series1" ChartType="Column" ChartArea="ChartArea1">
</asp:Series>
<asp:Series Name="Series2" ChartType="Column" ChartArea="ChartArea1">
</asp:Series>
</Series>
<ChartAreas>
<asp:ChartArea Name="ChartArea1">
</asp:ChartArea>
</ChartAreas>
</asp:Chart>

后台代码：

protected void Page_Load(object sender, EventArgs e)
{
DataTable dt = default(DataTable);
dt = CreateDataTable();

//设置图表的数据源
Chart1.DataSource = dt;

//设置图表Y轴对应项
Chart1.Series[0].YValueMembers = "Volume1";
Chart1.Series[1].YValueMembers = "Volume2";

//设置图表X轴对应项
Chart1.Series[0].XValueMember = "Date";

//绑定数据
Chart1.DataBind();
}
private DataTable CreateDataTable()
{
//Create a DataTable as the data source of the Chart control
DataTable dt = new DataTable();

//Add three columns to the DataTable
dt.Columns.Add("Date");
dt.Columns.Add("Volume1");
dt.Columns.Add("Volume2");

DataRow dr;

//Add rows to the table which contains some random data for demonstration
dr = dt.NewRow();
dr["Date"] = "Jan";
dr["Volume1"] = 3731;
dr["Volume2"] = 4101;
dt.Rows.Add(dr);

dr = dt.NewRow();
dr["Date"] = "Feb";
dr["Volume1"] = 6024;
dr["Volume2"] = 4324;
dt.Rows.Add(dr);

dr = dt.NewRow();
dr["Date"] = "Mar";
dr["Volume1"] = 4935;
dr["Volume2"] = 2935;
dt.Rows.Add(dr);

dr = dt.NewRow();
dr["Date"] = "Apr";
dr["Volume1"] = 4466;
dr["Volume2"] = 5644;
dt.Rows.Add(dr);

dr = dt.NewRow();
dr["Date"] = "May";
dr["Volume1"] = 5117;
dr["Volume2"] = 5671;
dt.Rows.Add(dr);

dr = dt.NewRow();
dr["Date"] = "Jun";
dr["Volume1"] = 3546;
dr["Volume2"] = 4646;
dt.Rows.Add(dr);

return dt;
}
