modify chart c#

I have good solutions from Robert Schutt at:

https://www.experts-exchange.com/questions/28489916/Fine-tune-column-chart-asp-net-c.html

In my posts,I have used two different chart samples. Now I am having a bit trouble consolidating the solutions.

Question How can I consolidate solution 1 through 6 with the code below it?

Thank you.

            // 1 don't show grid*********************************************************
            chartImage.ChartAreas[0].AxisX.MajorGrid.Enabled = false;
           chartImage.ChartAreas[0].AxisY.MajorGrid.Enabled = false;
           chartImage.ChartAreas[0].BorderWidth = 1;

           // 2 remove y labels?********************************************************
            chartImage.ChartAreas[0].AxisY.LabelStyle.Enabled = false;

            // 3 show value*************************************************************
            chartImage.Series[0].IsValueShownAsLabel = true;
            chartImage.Series[0].LabelForeColor = System.Drawing.Color.Blue;

            // 4 rotate x labels**********************************************************
           chartImage.ChartAreas[0].AxisX.LabelStyle.Angle = 90;

           //5.remove tick marks and add border*************************************
           chartImage.ChartAreas[0].AxisY.MajorTickMark.Enabled = false;

           //6. add border************************************************************
           chartImage.ChartAreas[0].BorderDashStyle = ChartDashStyle.Solid;
           chartImage.ChartAreas[0].BorderColor = System.Drawing.Color.DeepPink;

The above solutions (1-6) to be included with:
       double[] yValues = { 15, 60, 12, 13 };   //for column chart
        double[] yValues2 = { 30, 32, 30, 0 };   //for line
        string[] xValues = { "September", "October", "November", "December" };

        Chart chart = new Chart();

        Series series = new Series("Default");
        series.ChartType = SeriesChartType.Column;
        chart.Series.Add(series);

        Series series2 = new Series("Default2");
        series2.ChartType = SeriesChartType.Line;
        series2.Color = System.Drawing.Color.Red;
        series2.BorderWidth = 5; // this is actually the line width...
        chart.Series.Add(series2);

        ChartArea chartArea = new ChartArea();
        Axis yAxis = new Axis(chartArea, AxisName.Y);
        Axis xAxis = new Axis(chartArea, AxisName.X);

        chart.Series["Default"].Points.DataBindXY(xValues, yValues);
        chart.Series["Default2"].Points.DataBindXY(xValues, yValues2);
        chart.Series["Default"].Color = System.Drawing.Color.Blue; // change default if you want to
        chart.Series["Default"].Points[0].Color = System.Drawing.Color.Red;
        chart.Series["Default"].Points[chart.Series["Default"].Points.Count - 1].Color = System.Drawing.Color.Orange;

        chart.ChartAreas.Add(chartArea);

        chart.Width = new Unit(300, UnitType.Pixel);
        chart.Height = new Unit(200, UnitType.Pixel);
        string filename = "C:\\image\\Chart.png";
        chart.SaveImage(filename, ChartImageFormat.Png);
