WinForms Range Bar Chart Axis Not Rendering as Expected

Question

I am attempting to generate a ranged bar chart using System.Windows.Forms.DataVisualization.Charting.SeriesChartType.RangeBar. When I add the x axis as integers it renders correctly as shown below:

        int[] x = { 0, 0, 0, 1, 1, 1 };
        int[] y = { 10, 2, 35, 1, 10, 20 };
        int[] y2 = { 35, 4, 36, 2, 15, 40 };
        var xValue = x.ToList();
        var yValue1 = y.ToList();
        var yValue2 = y2.ToList();

        chart2.Series[0].Points.DataBindXY(x, y, y2);

However, when I swap the x axis integers to strings the chart does not render as above:

        string[] x = { "Test", "Test", "Test", "Test1", "Test1", "Test1" };
        int[] y = { 10, 2, 35, 1, 10, 20 };
        int[] y2 = { 35, 4, 36, 2, 15, 40 };
        var xValue = x.ToList();
        var yValue1 = y.ToList();
        var yValue2 = y2.ToList();
        chart2.Series[0].XValueType = 
        System.Windows.Forms.DataVisualization.Charting.ChartValueType.String;

        chart2.Series[0].Points.DataBindXY(x, y, y2);

Is there an elegant workaround to using string values for the x-axis while maintaining int or DateTime values for the y axis? Thanks in advance for your help.
