MSCharts最后轴标签隐藏

Question

我正在使用MSCharts并且正在使用轴的日期，并且不禁注意到轴标签是为最后一个网格线隐藏的。下图显示了这一点。

我正在使用的代码是：

Public Function buildXAxis(ByVal chartArea As ChartArea, ByVal min As DateTime, ByVal max As DateTime) As Axis
        Dim xAxis As New Axis(chartArea, AxisName.X) 'Chart Area is passed into the function
        With xAxis
            .Interval = 3 'This is the interval, so the next visible label should be 7/1/2013
            .IntervalType = DateTimeIntervalType.Months 
            .IntervalAutoMode = IntervalAutoMode.FixedCount
            .Maximum = max.ToOADate 'In this instance, it is 7/29/2013
            .Minimum = min.ToOADate 'In this instance, it is 1/29/2013
            .TitleAlignment = Drawing.StringAlignment.Center
            .TitleForeColor = Drawing.Color.FromArgb(129, 127, 124)
            .TextOrientation = TextOrientation.Auto
            .LabelAutoFitStyle = LabelAutoFitStyles.LabelsAngleStep45
            Dim xLabelStyle As New LabelStyle
            xLabelStyle.TruncatedLabels = False
            xLabelStyle.IsStaggered = False
            xLabelStyle.Format = "d"
            .LabelStyle = xLabelStyle
            .MajorGrid.LineColor = Drawing.Color.FromArgb(129, 127, 124)
            .MinorGrid.LineColor = Drawing.Color.FromArgb(129, 127, 124)
            .MajorTickMark.LineColor = Drawing.Color.FromArgb(129, 127, 124)
            .MinorTickMark.LineColor = Drawing.Color.FromArgb(129, 127, 124)
        End With
        Return xAxis
    End Function

有人知道为什么隐藏这些标签吗？根据代码，网格线在正确的位置，（每3个月），但轴标签根本没有显示，这实际上是修改此代码的唯一地方

Answer 1

LabelStyle.IsEndLabelVisible控制是否显示第一个和最后一个标签。

Here is the MSDN entry.

我猜你没有发布的代码中的某个地方是这样的：

Dim chartingArea As New ChartArea
chartingArea.AxisX.LabelStyle.IsEndLabelVisible = False

您需要将其更改为true或完全删除它，因为它默认为true。
