Winforms范围条形图轴未预期渲染

Question

我正在尝试使用System.Windows.Forms.Datavisualization.charting.seriescharttype.rangebar生成范围的条形图。当我将X轴添加为整数时，它会正确渲染如下所示：

        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);

但是，当我将x轴整数交换为串联时，图表并不如上所述：

        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);

您可以尝试！

            int[] tmpx = { 0, 0, 0, 1, 1, 1 };
            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();
            for (int i = 0; i<x.Length; i++)
            {
                int index = chart1.Series[0].Points.AddXY(tmpx[i], y[i], y2[i]);
                chart1.Series[0].Points[index].AxisLabel = x[i];
            }
