마이크로 차트에서 X 축 레이블로 날짜를 표시하는 방법

Question

나는 날짜순으로 점을 표시하는 코드 뒤에있는 내 차트를 얻는 방법을 알아 내려고 노력하고 있습니다. 내 포인트는 데이터베이스에서 날짜로 x 축 레이블을 설정할 때마다 완벽하게 잘 보여 주지만, 프로그램은 적합합니다. 누군가가 이것을 어떻게 코드에 표시 할 수 있습니까?

마지막으로 내가 누락 된 부분을 찾아 냈습니다. 데이터베이스의 날짜를 표시하려면 해당 날짜를 시리즈의 Points로 설정해야합니다. 다른 사람들을 돕기 위해 내가 해왔 던 코드가 있습니다.

private void BPChart_Load(object sender, EventArgs e) 
    { 
     chart1 = new Chart(); 

     ChartArea chartArea1 = new ChartArea(); 
     chart1.ChartAreas.Add(chartArea1); 
     chart1.ChartAreas["ChartArea1"].AxisX.Title = "Dates"; 
     chart1.ChartAreas["ChartArea1"].AxisY.Title = "BP Rates"; 
     Series series1 = new Series(); 
     Series series2 = new Series(); 

     chart1.Series.Add(series1); 
     chart1.Series.Add(series2); 

     // Add data points to the first series 
     int i = 0; 
     string ConnStr1 = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString; 
     SqlCeConnection conn = new SqlCeConnection(ConnStr1); 
     string GetBPReadings = "SELECT Systolic, Diastolic, [Date] from Bp where [Date] BETWEEN '5/1/2000' AND '5/8/2000'"; 
     SqlCeCommand cmd = new SqlCeCommand(GetBPReadings, conn); 
     conn.Open(); 
     SqlCeDataReader rdrBP = cmd.ExecuteReader(); 
     while (rdrBP.Read()) 
     { 
      series1.Points.Add(Convert.ToInt32(rdrBP.GetValue(0).ToString())); 
      series2.Points.Add(Convert.ToInt32(rdrBP.GetValue(1).ToString())); 
      chart1.Series["Series1"].Points[i].AxisLabel = rdrBP.GetValue(2).ToString(); 
      i++; 
     } 
     conn.Close(); 

     chart1.Series["Series1"].ChartType = SeriesChartType.Line; 
     chart1.Series["Series2"].ChartType = SeriesChartType.Line; 

     chart1.Series["Series1"].Color = System.Drawing.Color.Red; 
     chart1.Series["Series2"].Color = System.Drawing.Color.Blue; 

     // Set chart control location 
     chart1.Location = new System.Drawing.Point(0, 0); 

     // Set Chart control size 
     chart1.Size = new System.Drawing.Size(800, 600); 

     // Add chart control to the form 
     this.Controls.AddRange(new System.Windows.Forms.Control[] { this.chart1 }); 
    } 
}
