自己做的一个图表控件，调用方法如下

下载控件保存为dll即可







使用方法：

protected void Page_Load(object sender, EventArgs e)
{

MyOWC1.DataSource = createTable();
MyOWC1.Attribute.KeyField = "name";
MyOWC1.Attribute.ValueFileds = new string[] { "vistis", "showname" };
MyOWC1.Attribute.signValues = new string[] { "美国", "中国" };
MyOWC1.Attribute.startDate = new DateTime(2007, 4, 1);
MyOWC1.Attribute.endDate = new DateTime(2007, 4, 19);
MyOWC1.Draw();
}
DataTable createTable()
{
Random rnd = new Random();
DataTable dt = new DataTable();
dt.Columns.Add("name");
dt.Columns.Add("vistis");
dt.Columns.Add("showname");
dt.Columns.Add("percent");
for (int i = 0; i < 8; i++)
{
DataRow dr = dt.NewRow();
dr["name"] = "2007-4-"+(i+1);
dr["vistis"] = rnd.Next(100, 1000).ToString();
dr["showname"] = rnd.Next(100, 1000).ToString();
dr["percent"] = rnd.Next(100, 1000).ToString();
dt.Rows.Add(dr);
}
return dt;

}
