我正在构建一个带有图表 ( system.windows.forms.datavisualization.Charting.ChartArea) 的 winforms 应用程序。此图表中的系列在 上具有日期/时间，并在 上AxisX浮动AxisY。无论我尝试什么设置ScaleView.MinSize，它总是像设置为 1 天一样ScaleView.MinSizeType工作AxisX

        chartArea1.AxisX.Enabled = System.Windows.Forms.DataVisualization.Charting.AxisEnabled.True;
        chartArea1.AxisX.LabelStyle.Format = "dd MMM\nHH:mm";
        chartArea1.AxisX.ScaleView.MinSize = 0.001D;
        chartArea1.AxisX.ScaleView.MinSizeType = System.Windows.Forms.DataVisualization.Charting.DateTimeIntervalType.Days;
        chartArea1.AxisX.ScaleView.SizeType = System.Windows.Forms.DataVisualization.Charting.DateTimeIntervalType.Hours;
        chartArea1.AxisX.ScaleView.SmallScrollMinSize = 15D;
        chartArea1.AxisX.ScaleView.SmallScrollMinSizeType = System.Windows.Forms.DataVisualization.Charting.DateTimeIntervalType.Minutes;
        chartArea1.AxisX.ScaleView.SmallScrollSize = 15D;
        chartArea1.AxisX.ScaleView.SmallScrollSizeType = System.Windows.Forms.DataVisualization.Charting.DateTimeIntervalType.Minutes;
        chartArea1.AxisX2.Enabled = System.Windows.Forms.DataVisualization.Charting.AxisEnabled.False;
        chartArea1.AxisX2.ScaleView.SmallScrollMinSizeType = System.Windows.Forms.DataVisualization.Charting.DateTimeIntervalType.Hours;
        chartArea1.AxisX2.ScaleView.SmallScrollSize = 15D;
        chartArea1.AxisX2.ScaleView.SmallScrollSizeType = System.Windows.Forms.DataVisualization.Charting.DateTimeIntervalType.Minutes;
        chartArea1.AxisY.Enabled = System.Windows.Forms.DataVisualization.Charting.AxisEnabled.True;
        chartArea1.AxisY.ScaleView.MinSize = 1D;
        chartArea1.AxisY.ScaleView.MinSizeType = System.Windows.Forms.DataVisualization.Charting.DateTimeIntervalType.Number;
        chartArea1.AxisY.ScaleView.SmallScrollMinSizeType = System.Windows.Forms.DataVisualization.Charting.DateTimeIntervalType.Number;
        chartArea1.AxisY.ScaleView.SmallScrollSize = 1D;
        chartArea1.AxisY.ScaleView.SmallScrollSizeType = System.Windows.Forms.DataVisualization.Charting.DateTimeIntervalType.Number;
        chartArea1.AxisY2.Enabled = System.Windows.Forms.DataVisualization.Charting.AxisEnabled.False;
        chartArea1.CursorX.IsUserEnabled = true;
        chartArea1.CursorX.IsUserSelectionEnabled = true;
        chartArea1.CursorY.IsUserEnabled = true;
        chartArea1.CursorY.IsUserSelectionEnabled = true;

AxisY数据类型 float 工作正常。也SmallScrollSize可以AxisX正常工作。但是为什么ScaleView.MinSize困扰着我呢？

该问题是由光标间隔引起的。默认情况下设置为 1，因此我无法选择小于 1（天）的间隔。通过将时间间隔更改为 0.01（14.4 分钟），这不再是问题。

chartArea1.CursorX.Interval = 0.01D;
