円グラフでユーザー名を追加

Question

私は円グラフにはかなり新しく、hh：mm：ssに秒を表示するものがありますが、ここに私のコードも含まれている必要があります。

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

ユーザー名の前に、時刻を付加します。

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);
