用C#绘柱形图(owc编程)

string strImageTag = "<IMG SRC='" + strRelativePath + "'/>";

return strImageTag;

}

}

---------------------------------------------------------------------------------

调用方式举例

//调用 在页面上打印一个Image来显示产生的统计图

public void ShowChartLine3()

{

DataSet ds = new DataSet();

ds.Tables.Add("Table1");

ds.Tables[0].Columns.Add("abc");

ds.Tables[0].Columns.Add("bcd");

ds.Tables[0].Rows.Add();

for (int i = 101; i < 120; i++)

{

DataRow row = ds.Tables[0].NewRow();

row["abc"] = i.ToString();

row["bcd"] = (i + 5).ToString();

ds.Tables[0].Rows.Add(row);

}

ChartLine3 ch = new ChartLine3();

Response.Write(ch.toChartLine3(ds, "bcd,abc", "abc,bcd", "参赛选手", "票数", "在线投票系统"));

}

}
