如何在Microsoft的.NET 4.0图表中将MinorGrid行的数量修复为固定数字？

Question

我试图在.NET 4.0图表中设置固定数量的次网格线,其X轴是对数刻度.

我尝试设置"Axis.Minor.Interval"属性,这只会使网格线消失.

chart1.ChartAreas[0].AxisX.IntervalAutoMode = IntervalAutoMode.VariableCount;
            chart1.ChartAreas[0].AxisX.IntervalType = DateTimeIntervalType.Number;
            chart1.ChartAreas[0].AxisX.Interval = 100d;

            chart1.ChartAreas[0].AxisX.MajorGrid.IntervalType = DateTimeIntervalType.Number;
            chart1.ChartAreas[0].AxisX.MajorGrid.IntervalOffsetType = DateTimeIntervalType.Number;
            chart1.ChartAreas[0].AxisX.MajorGrid.Interval = 10d;

            chart1.ChartAreas[0].AxisX.MinorGrid.IntervalType = DateTimeIntervalType.Number;
            chart1.ChartAreas[0].AxisX.MinorGrid.IntervalOffsetType = DateTimeIntervalType.Number;
            chart1.ChartAreas[0].AxisX.MinorGrid.Interval = 5;

我的目标是每十年有一个主要网格的对数刻度,显示10个小网格线.

谢谢

几个小时以同样的问题将我的头撞在墙上,似乎我偶然发现了答案:

令人费解的是,如果将MinorGrid Interval设置为1,那么您将获得传统的Logarithmic网格标记,每十年十个:

aChart.ChartAreas[0].AxisX.IsLogarithmic = true;
aChart.ChartAreas[0].AxisX.MinorGrid.Interval = 1;
aChart.ChartAreas[0].AxisX.MinorGrid.Enabled = true;

希望有所帮助.
