用餅圖添加用戶名

Question

我對餅圖非常新，我有一個顯示hh：mm：ss的秒，但我也需要包含的用戶名以及這是我的代碼。

string easystone = ConfigurationManager.ConnectionStrings["easystone"].ConnectionString; 

    SqlConnection con = new SqlConnection(easystone); 
    SqlDataAdapter graph = new SqlDataAdapter("SELECT[User] , sum(time) as [time] FROM avgtime3 group by[user]", con); 
    DataTable graphdata = new DataTable(); 
    graph.Fill(graphdata); 
    chart1.DataSource = graphdata; 
    chart1.ChartAreas["ChartArea1"].AxisX.Title = ""; 
    foreach (DataRow row in graphdata.Rows) 
    { 
     int total = (int)row["time"]; 
     int index = chart1.Series["Series1"].Points.AddXY(row["User"], new object[] { total }); 
     chart1.Series["Series1"].Points[index].Label = // I need the username to go here. 
     chart1.Series["Series1"].Points[index].Label = string.Format("{0:00}:{1:00}:{2:00}", (total/60)/60, (total/60) % 60, total % 60); 
    } 

Answer 1

在用戶名和時間前綴。

chart1.Series["Series1"].Points[index].Label = row["User"].ToString() + " : " + string.Format("{0:00}:{1:00}:{2:00}", (total/60)/60, (total/60) % 60, total % 60);
