Dokowanie legend w obszarze wykresu w C#

Question

Oto kod tworzenia 3 wykresów. Chcę zadokować legendę wewnątrz obszaru każdego wykresu, ale ja dostaję legendy na dole. Użyłem DockedToChartArea, ale to nie miało sensu. Chcę umieścić legendę w każdym obszarze wykresu.

for (int t = 0; t < ARF.Rows.Count; t += 1) 
{ 
    dv.RowFilter = FilterString1.ToString(); 

    Chart1.Series.Add("Series1" + t.ToString()); 
    Chart1.ChartAreas.Add("ChartArea1" + t.ToString()); 
    Chart1.Series[t].ChartArea = "ChartArea1" + t.ToString(); 

    if (dtReportDetails.Rows[0].ItemArray[7].ToString() == "Bar") 
    { 
     Chart1.Series[t].ChartType = SeriesChartType.Column; 
     Chart1.Series[t].BorderWidth = 2; 
     Chart1.Series[t].ToolTip = "(#VALX,#VALY)"; 
     Chart1.ChartAreas["ChartArea1" + t.ToString()].AxisX.Title = "Learning Domains"; 
     Chart1.ChartAreas["ChartArea1" + t.ToString()].AxisY.Title = "Covered"; 
     Chart1.Legends.Add("Legend1" + t.ToString()); 
     Chart1.Legends["Legend1" + t.ToString()].Enabled = false; 
     // Chart1.Legends["Legend1" + t.ToString()].Docking = Docking.Bottom; 
     Chart1.Legends["Legend1" + t.ToString()].Alignment = System.Drawing.StringAlignment.Center; 
     Chart1.Legends["Legend1" + t.ToString()].DockedToChartArea = "ChartArea1" + t.ToString(); 
     // Chart1.Legends["Legend1" + t.ToString()].IsDockedInsideChartArea = false; 
     Random random = new Random(); 
     foreach (var item in Graph.Series[0].Points) 
     { 
      System.Drawing.Color c = System.Drawing.Color.FromArgb(random.Next(0, 255), random.Next(0, 255), random.Next(0, 255)); 
      item.Color = c; 

     } 

     Chart1.Series[t]["PointWidth"] = "0.2"; 
     Chart1.Series[t]["BarLabelStyle"] = "Center"; 
     Chart1.Series[t]["PixelPointDepth"] = "99";

Answer 1

Dziękuję.

if (t == ARF.Rows.Count) 
{ 
    for (int s = 0; s < ARF.Rows.Count; s++) 
    { 
     Chart1.Legends.Add(new Legend("Legends1" + s.ToString())); 
     Chart1.Series["Series1" + s.ToString()].Legend = "Legends1" + s.ToString(); 
     Chart1.Legends["Legends1" + s.ToString()].DockedToChartArea = "ChartArea1" + s.ToString(); 
    } 
} 

Answer 2

można ręcznie wyregulować położenie czatu legendy przez

Chart1.Legends["Legend1"].Position.Auto = false; 
Chart1.Legends["Legend1"].Position = new ElementPosition(x, y, width, hight); 

Musisz ustawić elementu przez ElementPosition z wszystkimi wymaganymi parametrami.

Możesz także sprawdzić tutaj Example, która wyjaśnia, jak dopasować legendę w obszarze wykresu.

Answer 3

Dzięki za sugestię. Miałem problemy w VB.NET uzyskanie legendy, aby dodać do każdego chartarea, dopóki nie stosuje się następującą:

For k = 1 To NumChartAreas 
     chart1.ChartAreas.Add(k - 1) 
     chart1.ChartAreas(k - 1).Name = k - 1 

     'Add new legend to each chartarea 
     chart1.Legends.Add(New Legend("Legends" + k.ToString())) 
     chart1.Legends("Legends" + k.ToString()).DockedToChartArea = chart1.ChartAreas(k - 1).Name 
     chart1.Legends("Legends" + k.ToString()).Docking = Docking.Right 

     'Populate series data for this chartarea 
     Cnt = -1 
     For j = 1 To NumSeries 'Number of series in this chartarea 
      Cnt += 1 
      chart1.Series.Add(Cnt) 
      For i = 1 To NumDataPoints ' Number of datapoints in this series 
       chart1.Series(Cnt).Points.AddXY(i, Rnd()) 
      Next 
      chart1.Series(Cnt).Legend = "Legends" + k.ToString 
     Next j 
    Next k
