       例如:

//檢索重慶市月平均氣溫
string sql = @"select DATEPART (month,dtmMeasure) as 'Month',AVG (fltTemperature ) as 'AvgTemp' from TblTemperature
        where chvCityName ='重慶' group by DATEPART (month,dtmMeasure) order by Month desc";
DataSet ds = SqlHelper.Select(CommandType.Text, sql, null);
//設置圖表背景顏色
this.Chart1.BackColor = Color.LightPink;
//設置圖表邊框樣式
this.Chart1.BorderlineColor = Color.Green;
//邊框線寬度
this.Chart1.BorderlineWidth = 5;
//圖表邊框西安為細線
this.Chart1.BorderlineDashStyle = ChartDashStyle.Solid;
//標題
this.Chart1.Titles.Add("重慶市月平均氣溫走勢圖");
//設置圖表X,Y軸綁定的列
this.Chart1.Series[0].XValueMember = "Month";
this.Chart1.Series[0].YValueMembers = "AvgTemp";
//設置每個數據點標簽上顯示的值為數據點的值
this.Chart1.Series[0].IsValueShownAsLabel = true;
//設置數據點標簽的文本格式]
this.Chart1.Series[0].LabelFormat = "{0}℃";
//綁定數據源
this.Chart1.DataSource = ds;
this.Chart1.DataBind();

       //折線圖
