Fastlineチャートに複数の線をプロットできません

Question

私はFastline Chartを選択しようとしています。私はちょうど同じチャートに平均をプラスしたデータをプロットしたいと思います。簡単にする必要がありますが、エラーが発生する "mscorlib.dllで 'System.Reflection.TargetInvocationException'型の未処理の例外が発生しました。私は[AverageTime「]と呼ばれる第二シリーズコメントアウトする場合

機能は、以下の通りである私は、コンパイルをし、1行で動作します。

機能に注意してください、私が使用非同期（.NET 4.5）である」のawait私が待っているスレッドを持っていると推測すると、これと何か関係があるかどうかは分かりません。

どのようにすればいいのですか？問題？

Answer 1

多くのヘッドスクラッチの後、私は 問題。 1つの小さな点がありませんでした。これは、グラフ作成キャンバスのメンバーとして宣言された2番目のシリーズ、Series ["AverageTime"]を持たなかったことです。

これを修正するには、[プロパティ]に行き、コレクションをクリックしてメンバーを追加してください。AverageTimeそれが完了したら、チャートキャンバスにポイントを描画することができました。可能な場合は、最小限のREPROを作成してください

は、だから今は

if (ckbx_plot.Checked) 
    { 
     chrt_timings.Series["ResponseTimes"].ChartType = SeriesChartType.FastLine; //set type 
     chrt_timings.Series["ResponseTimes"].Color = Color.Blue; //set colour 

     chrt_timings.Series["AverageTime"].ChartType = SeriesChartType.FastLine; //set type 
     chrt_timings.Series["AverageTime"].Color = Color.Red; //set colour 
     chrt_timings.Series["AverageTime"].BorderDashStyle = ChartDashStyle.Dash; 

     chrt_timings.Legends.Clear(); // We do not need a legend 
     chrt_timings.ChartAreas[0].AxisX.IsMarginVisible = false; 
    } 

以下の行を初期化し、今私は、データ

if (ckbx_restrict_graph.Checked) 
       { //shows just set number of points, add a new point remove an old point 
        if (chrt_timings.Series["ResponseTimes"].Points.Count() >= Convert.ToInt16(txtbx_axispoints.Text)) chrt_timings.Series["ResponseTimes"].Points.RemoveAt(0); 
        chrt_timings.Series["ResponseTimes"].Points.Add(timestamp); 
        chrt_timings.Series["ResponseTimes"].ToolTip = timestamp.ToString(); 

         if (chrt_timings.Series["AverageTime"].Points.Count() >= Convert.ToInt16(txtbx_axispoints.Text)) chrt_timings.Series["Average Time"].Points.RemoveAt(0); 
         chrt_timings.Series["AverageTime"].Points.Add(ave_plot); 

        chrt_timings.ResetAutoValues(); 
       } 
       else 
       { //squash all points onto the same canvas 
        recursive_counter++; 
        chrt_timings.Series["ResponseTimes"].Points.AddXY(recursive_counter, timestamp); 
        chrt_timings.Series["ResponseTimes"].ToolTip = timestamp.ToString(); 

        chrt_timings.Series["AverageTime"].Points.AddXY(ave_plot, timestamp); 
       }
