如何在Microsoft的.NET 4.0图表中将MinorGrid行的数量修复为固定数量？ [英] How can I fix the number of MinorGrid lines to a fixed number in Microsoft's .NET 4.0 Chart?

问题描述

我试图在一个.NET 4.0图表中设置固定数量的次要网格线，其X轴为对数刻度。

I am trying to set a fixed number of minor grid lines in a .NET 4.0 Chart whose X axis is in a Logarithmic scale.

我尝试设置Axis.Minor.Interval属性，这只会使网格线消失。

I try to set the "Axis.Minor.Interval" property, this only makes the grid lines disappear.

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网格的对数刻度，显示10条次网格线。

My goal is to have a logarithmic scale with a major grid every decade, showing 10 minor grid lines.

推荐答案

有相同的确切问题，它似乎我偶然得到的答案：

After hours of banging my head on the wall with the same exact problem, it seems I've stumbled onto the answer:

不可避免地，如果你设置MinorGrid间隔为1，那么你得到传统的对数网格标记，每十年十次：

Inexplicably, if you set the MinorGrid Interval to 1, then you get the traditional Logarithmic grid marks, ten per decade:

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

希望有帮助。
