    // Create a new chart.

    // Create two series.
    Series series1 = new Series("Series 1", ViewType.Bar);
    Series series2 = new Series("Series 2", ViewType.Line);

    // Add points to them, with their arguments different.
    series1.Points.Add(new SeriesPoint("A", 10));
    series1.Points.Add(new SeriesPoint("B", 12));
    series1.Points.Add(new SeriesPoint("C", 17));

    series2.Points.Add(new SeriesPoint("III", 2500));
    series2.Points.Add(new SeriesPoint("IV", 3300));

    // Add both series to the chart.
    chartControl1.Series.AddRange(new Series[] { series1, series2 });

    // Hide the legend (optional).

    // Assign the series2 to the created axes.
    ((LineSeriesView)series2.View).AxisX = myAxisX;
    ((LineSeriesView)series2.View).AxisY = myAxisY;

    myAxisY.Title.TextColor = Color.Blue;
    myAxisY.Label.TextColor = Color.Blue;
    myAxisY.Color = Color.Blue;

    // Add the chart to the form.
    chartControl1.Dock = DockStyle.Fill;
    this.Controls.Add(chartControl1);
