C＃ - Windows窗体图 - AxisX.IntervalOffset不起作用

Question

我试图抵消我的majorGrids和LabelStyle。当我设置一个间隔时，它工作正常，但当我试图抵消该间隔时，我无法使其工作。

绘制的数据沿x轴具有固定点。它们总是相同且对数（不确定是否相关）。

无论IntervalOffset的价值如何，我都尝试过它总是一样的。我也尝试过设置IntervalOffsetType和Interval类型（我在代码中尝试过不同的东西）。我想要的是标签和majorGridLines从63开始并重复每三个点。

以下是一些代码：

包含图表的表单中的代码

private void setupChart()
{
    // Setup Chart
    chartPathData.Legends[0].Docking = Docking.Bottom;


    chartPathData.ChartAreas[0].AxisX.LabelStyle.IntervalOffset = 1;
    chartPathData.ChartAreas[0].AxisX.LabelStyle.Interval = 3;
    chartPathData.ChartAreas[0].AxisX.LabelStyle.IntervalType = 0;
    chartPathData.ChartAreas[0].AxisX.LabelStyle.IntervalOffsetType = 0;

    chartPathData.ChartAreas[0].AxisX.MajorGrid.IntervalOffset = 1;
    chartPathData.ChartAreas[0].AxisX.MajorGrid.Interval = 3;
    chartPathData.ChartAreas[0].AxisX.MajorGrid.IntervalType = DateTimeIntervalType.Number;
     chartPathData.ChartAreas[0].AxisX.MajorGrid.IntervalOffsetType = DateTimeIntervalType.Number;


    chartPathData.ChartAreas[0].AxisY.Minimum = 0;
    chartPathData.ChartAreas[0].AxisY.Maximum = 100;
}

private void GraphPath(Pathdata pathData, string pathName, Color color)
{
    var seriesPath = new Series
    {
        Name = pathName,
        IsVisibleInLegend = true,
        IsXValueIndexed = true,
        Color = color,
        ChartType = SeriesChartType.FastLine
    };

    chartPathData.Series.Add(seriesPath);

    // GraphPath just creates a graphable version
    // of pathData assigning X values at the corresponding
    // properties (creating x,y points)
    GraphPath graphPath = new GraphPath(pathData);
    foreach (GraphPoint point in graphPath.GraphPoints)
    {               
        seriesPath.Points.AddXY(point.x, point.y);
    }

}

DataPath类

    public class DataPath
{        
    public ThirdOctaveValue A50 { get; set; }
    public ThirdOctaveValue A63 { get; set; }
    public ThirdOctaveValue A80 { get; set; }
    public ThirdOctaveValue A100 { get; set; }
    public ThirdOctaveValue A125 { get; set; }
    public ThirdOctaveValue A160 { get; set; }
    public ThirdOctaveValue A200 { get; set; }
    public ThirdOctaveValue A250 { get; set; }
    public ThirdOctaveValue A315 { get; set; }
    public ThirdOctaveValue A400 { get; set; }
    public ThirdOctaveValue A500 { get; set; }
    public ThirdOctaveValue A630 { get; set; }
    public ThirdOctaveValue A800 { get; set; }
    public ThirdOctaveValue A1000 { get; set; }
    public ThirdOctaveValue A1250 { get; set; }
    public ThirdOctaveValue A1600 { get; set; }
    public ThirdOctaveValue A2000 { get; set; }
    public ThirdOctaveValue A2500 { get; set; }
    public ThirdOctaveValue A3150 { get; set; }
    public ThirdOctaveValue A4000 { get; set; }
    public ThirdOctaveValue A5000 { get; set; }
}

以下是结果
