试图在同一页面上显示两个图表

Question

我正在使用 win 表单应用程序 我正在使用单个 ms 图表控件并生成两个不同的图表，并希望通过使用布尔概述在同一页面上显示两个图表（这意味着当应用程序运行时将显示一个图表，如果您单击该图表，我想显示另一个图表）与此）通过以下代码

      private void chartControlMemberTotals_Click(object sender, EventArgs e)
     {

       kpiMemberTotalsForm.DrawKpi(this.chartControlMemberTotals, startDate, endDate, true);
     }





 public void DrawKpi(Chart targetChartControl, DateTime StartDate, DateTime EndDate, bool Overview)
{
  try
  {    
    Series series = null;
    Title title;
    string area;


     targetChartControl.ChartAreas.Clear();
      targetChartControl.Series.Clear();
      targetChartControl.Titles.Clear();

        area = "Status";
      targetChartControl.ChartAreas.Add(area);
      series = targetChartControl.Series.Add(area);
      series.ChartArea = area;
      if (!Overview)
      {
        title = targetChartControl.Titles.Add("Member status");
        title.IsDockedInsideChartArea = Overview;
        title.Alignment = ContentAlignment.TopLeft;
        title.DockedToChartArea = area;


        targetChartControl.Titles.Add("").DockedToChartArea = area;
      }

      targetChartControl.Titles.Add("Members status").DockedToChartArea = area;

      area = " Live members mebershiptypes";
      targetChartControl.ChartAreas.Add(area);
      series = targetChartControl.Series.Add(area);
      series.ChartArea = area;

      if (!Overview)
      {
        title = targetChartControl.Titles.Add("Live Status  members  By MemberShip Type");
        title.Font = new Font(FontFamily.GenericSansSerif, 10, FontStyle.Bold);
        title.Alignment = ContentAlignment.TopLeft;
        title.DockedToChartArea = area;

        targetChartControl.Titles.Add("").DockedToChartArea = area;
        targetChartControl.Titles.Add("Live memberships").DockedToChartArea = area;
      }


      foreach (Title chartTitle in targetChartControl.Titles)
      {
        chartTitle.IsDockedInsideChartArea = false;
      }

      foreach (ChartArea chartArea in targetChartControl.ChartAreas)
      {
        chartArea.Area3DStyle.Enable3D = true;
        chartArea.AxisX.LabelStyle.IsEndLabelVisible = true;
      }

      if (!Overview)
      {
        foreach (Series chartSerie in targetChartControl.Series)
        {


          chartSerie.ChartType = SeriesChartType.StackedColumn;
          chartSerie["ColumnDrawingStyle"] = "SoftEdge";
          chartSerie["LabelStyle"] = "Top";
          chartSerie.IsValueShownAsLabel = true;
                    //series.CustomProperties = "DrawingStyle=Cylinder";
        chartSerie.BackGradientStyle = GradientStyle.DiagonalLeft;

        }
      }

      foreach (Series chartSeries in targetChartControl.Series)
      {
        chartSeries.ChartType = SeriesChartType.Pie;

        if (!Overview)
        {
          chartSeries["PieLabelStyle"] = "Outside";
        }
        else
        {

          chartSeries["PieLabelStyle"] = "Disabled";
        }
        chartSeries["DoughnutRadius"] = "30";
        chartSeries["PieDrawingStyle"] = "SoftEdge";

        chartSeries.BackGradientStyle = GradientStyle.DiagonalLeft;
      }

      foreach (Legend legend in targetChartControl.Legends)
      {
        legend.Enabled = false;
      }

      if (!Overview)
      {
        DataTable Accept = null;
        Accept = KPIData.livemembersmembershiptype(mf);
        targetChartControl.Series[0].Points.DataBindXY(Accept.Rows, "mshipname", Accept.Rows, "count");

        foreach (Series chartSeries in targetChartControl.Series)
        {
          foreach (DataPoint point in chartSeries.Points)
          {

            switch (point.AxisLabel)
            {
              case "Silver membership": point.Color = Color.Red; break;

            }
            point.Label = string.Format("{0:0}", point.YValues[0]);
          }
        }
      }
      DataTable reportsfull = null;
      reportsfull = KPIData.MembershipTotals(StartDate, EndDate, mf);

        targetChartControl.Series[0].Points.DataBindXY(reportsfull.Rows, "Status", reportsfull.Rows, "Value");


        foreach (Series chartSeries in targetChartControl.Series)
        {
          foreach (DataPoint point in chartSeries.Points)
          {
            switch (point.AxisLabel)
            {
              case "New": point.Color = Color.Cyan; break;
              case "Live": point.Color = Color.Green; break;

            }

            point.Label = string.Format("{0:0} - {1}", point.YValues[0], point.AxisLabel);
          }
        }
    }
 catch
  {
  }
  }

，但当应用程序运行时，它显示图表，当我单击图表时，它只显示一个图表，我不知道为什么它不显示另一张图表，

指定系列和图例是否有任何错误MS图表和来自数据库的数据是正确的

查看您的代码，您正在数据绑定同一系列targetChartControl.Series[0]。
我认为您需要尝试定义两个单独的图表系列并将它们分配给您已经定义的两个不同的图表区域。那应该可以解决你的问题。
