VB .NET中Chart控件如何让AxisLabel对齐

目的：柱状图用来统计某个区间的数量，在X轴用AxisLabel显示区间的上限和下限
问题：因为设置IsStaggered = True，所以AxisLabel的显示效果是分两层的，如何设置属性才能放到一样水平？ 希望大家帮忙指教，万分感谢！！ 本人QQ:865207156

代码:
Chart1.ChartAreas(0).AxisX.LabelStyle.IsStaggered = True
Chart1.ChartAreas(0).AxisX.LabelStyle.Angle = 90

    Chart1.Series(0).Points.Item(0).AxisLabel = "0.004\n\n0.000"
    Chart1.Series(0).Points.Item(0).YValues(0) = 85

    Chart1.Series(0).Points.Item(1).AxisLabel = " "
    Chart1.Series(0).Points.Item(1).YValues(0) = 90

    Chart1.Series(0).Points.Item(2).AxisLabel = "0.012\n\n0.008"
    Chart1.Series(0).Points.Item(2).YValues(0) = 45
