multiple boxplots in one chart in C#

Question

I'm trying to figure out how to get c# to put in more than one boxplot in a chart. There's not much help in the internet as soon as it comes to c# instead of R or python. So I'm asking: What did I do wrong or miss in this code?

   private void on_boxplot(object sender, EventArgs e)
    {                  
        List<String> xValue = new List<String> { "Ala (A)", "Arg (R)", "Asn (N)", "Asp (D)", "Cys (C)", "Gln (Q)", "Glu (E)", "Gly (G)", "His (H)", "Ile (I)", "Leu (L)", "Lys (K)", "Met (M)", "Phe (F)", "Pro (P)", "Ser (S)", "Thr (T)", "Trp (W)", "Tyr (Y)", "Val (V)", "Pyl (O)", "Sec (U)" };
        Chart Chart = new Chart();
        Chart.chart_main.Series.Clear();
        Chart.chart_main.Series.Add("BoxPlotSeries");
        for (Int32 i = 0; i < xValue.Count; i++)
        {
            Chart.chart_main.Series.Add(xValue[i]); 
        }

        for (Int32 i = 0; i < DYL; i++)
        {
            if (Data[i, 0] == null) break;
            Chart.chart_main.Series[xValue[0]].Points.AddY(boxplot_helper(i, Dataslots[0]));
            Chart.chart_main.Series[xValue[1]].Points.AddY(boxplot_helper(i, Dataslots[1]));
            Chart.chart_main.Series[xValue[2]].Points.AddY(boxplot_helper(i, Dataslots[2]));
            Chart.chart_main.Series[xValue[3]].Points.AddY(boxplot_helper(i, Dataslots[3]));
            Chart.chart_main.Series[xValue[4]].Points.AddY(boxplot_helper(i, Dataslots[4]));
            Chart.chart_main.Series[xValue[5]].Points.AddY(boxplot_helper(i, Dataslots[5]));
            Chart.chart_main.Series[xValue[6]].Points.AddY(boxplot_helper(i, Dataslots[6]));
            Chart.chart_main.Series[xValue[7]].Points.AddY(boxplot_helper(i, Dataslots[7]));
            Chart.chart_main.Series[xValue[8]].Points.AddY(boxplot_helper(i, Dataslots[8]));
            Chart.chart_main.Series[xValue[9]].Points.AddY(boxplot_helper(i, Dataslots[9]));
            Chart.chart_main.Series[xValue[10]].Points.AddY(boxplot_helper(i, Dataslots[10]));
            Chart.chart_main.Series[xValue[11]].Points.AddY(boxplot_helper(i, Dataslots[11]));
            Chart.chart_main.Series[xValue[12]].Points.AddY(boxplot_helper(i, Dataslots[12]));
            Chart.chart_main.Series[xValue[13]].Points.AddY(boxplot_helper(i, Dataslots[13]));
            Chart.chart_main.Series[xValue[14]].Points.AddY(boxplot_helper(i, Dataslots[14]));
            Chart.chart_main.Series[xValue[15]].Points.AddY(boxplot_helper(i, Dataslots[15]));
            Chart.chart_main.Series[xValue[16]].Points.AddY(boxplot_helper(i, Dataslots[16]));
            Chart.chart_main.Series[xValue[17]].Points.AddY(boxplot_helper(i, Dataslots[17]));
            Chart.chart_main.Series[xValue[18]].Points.AddY(boxplot_helper(i, Dataslots[18]));
            Chart.chart_main.Series[xValue[19]].Points.AddY(boxplot_helper(i, Dataslots[19]));
            Chart.chart_main.Series[xValue[20]].Points.AddY(boxplot_helper(i, Dataslots[20]));
            Chart.chart_main.Series[xValue[21]].Points.AddY(boxplot_helper(i, Dataslots[21]));     
        }

        Chart.chart_main.Series["BoxPlotSeries"].ChartType = SeriesChartType.BoxPlot;
        Chart.chart_main.Series["BoxPlotSeries"]["BoxPlotSeries"] = xValue[0];

        Chart.chart_main.ChartAreas.Add("BoxPlot");
        Chart.chart_main.Series["BoxPlotSeries"].ChartArea = "BoxPlot";

        Chart.chart_main.Series["BoxPlotSeries"]["BoxPlotWhiskerPercentile"] = "0";
        Chart.chart_main.Series["BoxPlotSeries"]["BoxPlotPercentile"] = "25";
        Chart.chart_main.Series["BoxPlotSeries"]["BoxPlotShowAverage"] = "true";
        Chart.chart_main.Series["BoxPlotSeries"]["BoxPlotShowMedian"] = "true";
        Chart.chart_main.Series["BoxPlotSeries"]["BoxPlotShowUnusualValues"] = "true";
        Chart.chart_main.Series["BoxPlotSeries"]["MaxPixelPointWidth"] = "15";
        Chart.chart_main.Series["BoxPlotSeries"].BorderWidth = 2;
        Chart.Show();

    }

    private Double boxplot_helper(Int32 i, Int32 slot)
    {
        String Santas = Data[i, slot].Replace('.', ',').TrimEnd('%').Trim();
        Double LittleHelper = Convert.ToDouble(Santas);
        return LittleHelper;

    }

Above is the outcome but I'd like 22 of those. Anyone happen to have any kind of idea how to solve this?

Answer 1

You can create multiple boxplots as

Chart.chart_main.Series["BoxPlotSeries"]["BoxPlotSeries"] = string.Join(";", xValue);

Answer 2

One might be interested in what I did:

        List<String> Series = new List<String>();
        for (Int32 i = 0; i < 22; i++)
        {
            Series.Add(xValue[i]);
        }
        String Helper = String.Join("; ", Series);

        Chart.chart_main.Series["BoxPlotSeries"]["BoxPlotSeries"] = Helper;

And the outcome:
