WinFormsチャートコントロール付きグループ化棒グラフ

Question

このようなMS Excelグループ化棒グラフで作成できます。

WinForms Chart Controlを介して同じChartを作成する必要があります。

私はこのコードを試していますが、MS Excelのような正しいチャートを作成するためには、より洗練されたソリューションが必要です。

グループ化された棒グラフを作成するには、コードを修正してください。 Googleといくつかの実験を使用することにより （そして、この偉大なマイクロソフトの例https://code.msdn.microsoft.com/mschart/Release/ProjectReleases.aspx?ReleaseId=4418を助けていません）

のDataSource

DataTable dtExc = new DataTable(); 

// Create columns 
dtExc.Columns.Add((new DataColumn("StoodType", typeof(int))).Caption = "Stood"); 
dtExc.Columns.Add((new DataColumn("TotalMinutes", typeof(double))).Caption = "Time"); 

foreach (var exDataitem in allDataExc) 
{ 
    DataRow drToAdd = dtExc.NewRow(); 

    drToAdd[0] = exDataitem.StoodTypeFullName; 
    drToAdd[1] = exDataitem.TotalMinutes; 

    dtExc.Rows.Add(drToAdd); 
} 

チャート

public Chart GenerateExcChart(DataTable dtChartDataSource, int width, int height, string bgColor, SeriesChartType seriesChartType, 
      string axisXTitle, string axisYTitle) 
     { 
      Chart chart = new Chart() 
      { 
       Width = width, 
       Height = height 
      }; 


      chart.Legends.Add(new Legend() { Name = "Legend" }); 
      chart.Legends[0].Docking = Docking.Bottom; 
      ChartArea chartArea = new ChartArea() { Name = "ChartArea" }; 

      //Remove X-axis grid lines 
      chartArea.AxisX.MajorGrid.LineWidth = 0; 
      chartArea.AxisX.Title = axisXTitle; 

      chartArea.AxisX.IntervalAutoMode = IntervalAutoMode.VariableCount; 
      chartArea.AxisX.IntervalType = DateTimeIntervalType.Number; 

      //Remove Y-axis grid lines 
      chartArea.AxisY.MajorGrid.LineWidth = 0; 
      chartArea.AxisY.Interval = 1; 
      chartArea.AxisY.Title = axisYTitle; 

      //Chart Area Back Color 
      chartArea.BackColor = Color.FromName(bgColor); 
      chart.ChartAreas.Add(chartArea); 
      chart.Palette = ChartColorPalette.BrightPastel; 
      string series = string.Empty; 

      //create series and add data points to the series 
      if (dtChartDataSource != null) 
      { 
       foreach (DataColumn dc in dtChartDataSource.Columns) 
       { 
        //a series to the chart 
        if (chart.Series.FindByName(dc.ColumnName) == null) 
        { 
         series = dc.ColumnName; 
         chart.Series.Add(series); 
         chart.Series[series].ChartType = seriesChartType; 
        } 

        var rowIndex = 0; 
        //Add data points to the series 
        foreach (DataRow dr in dtChartDataSource.Rows) 
        { 
         double dataPoint = 0; 
         double.TryParse(dr[dc.ColumnName].ToString(), out dataPoint); 

         var objDataPoint = new DataPoint(); 
         objDataPoint.YValues = new double[] { dataPoint }; 
         objDataPoint.XValue = rowIndex + 1; 
         objDataPoint.AxisLabel = rowIndex.ToString(); 

         if (dataPoint == 0) 
         { 
          objDataPoint.IsEmpty = true; 
         } 

         chart.Series[series].Points.Add(objDataPoint); 
         rowIndex++; 
        } 
       } 
      } 

      return chart; 
     } 

Answer 1

それがどのようなIないので、私は、コードを修正必要。

public Chart GenerateExcChart(DataTable dtChartDataSource, int width, int height, string bgColor, SeriesChartType seriesChartType, 
      string axisXTitle, string axisYTitle) 
     { 
      Chart chart = new Chart() 
      { 
       Width = width, 
       Height = height 
      }; 

      chart.Legends.Add(new Legend() { Name = "Legend" }); 
      chart.Legends[0].Docking = Docking.Bottom; 
      ChartArea chartArea = new ChartArea() { Name = "ChartArea" }; 

      chartArea.AxisX.MajorGrid.LineWidth = 0;//Remove X-axis grid lines 
      chartArea.AxisY.MajorGrid.LineWidth = 0;//Remove Y-axis grid lines 

      chartArea.AxisX.IntervalAutoMode = IntervalAutoMode.VariableCount; 
      chartArea.AxisY.IntervalAutoMode = IntervalAutoMode.VariableCount; 
      chartArea.AxisX.IntervalType = DateTimeIntervalType.Number; 
      chartArea.AxisY.IntervalType = DateTimeIntervalType.Number; 

      chartArea.AxisX.LabelStyle.Angle = -45; 

      chartArea.AxisX.Title = axisYTitle; 
      chartArea.AxisY.Title = axisXTitle; 

      //Chart Area Back Color 
      chartArea.BackColor = Color.FromName(bgColor); 
      chart.ChartAreas.Add(chartArea); 
      chart.Palette = ChartColorPalette.BrightPastel; 
      string series = string.Empty; 

      //create series and add data points to the series 
      if (dtChartDataSource != null) 
      { 
       series = "Series1"; 
       chart.Series.Add(series); 
       chart.Series[series].ChartType = SeriesChartType.Column; 
       chart.Series[series].XValueType = ChartValueType.Auto; 
       chart.Series[series].YValuesPerPoint = 1; 
       chart.Series[series].YValueType = ChartValueType.Auto; 

       var rowIndex = 0; 

       //Add data points to the series 
       foreach (DataRow dr in dtChartDataSource.Rows) 
       { 
        double dataPoint; 
        DataPoint objDataPoint = new DataPoint(); 

        objDataPoint.AxisLabel = dr[dtChartDataSource.Columns[0].ColumnName].ToString(); 

        double.TryParse(dr[dtChartDataSource.Columns[1].ColumnName].ToString(), out dataPoint); 


        objDataPoint.XValue = rowIndex; 
        objDataPoint.YValues = new double[] { dataPoint }; 

        chart.Series[series].Points.Add(objDataPoint); 

        rowIndex++; 
       } 
      } 

      chart.Series[0].IsVisibleInLegend = false; 

      return chart; 
     }
