使用 ZedGraph 控制，说我策划的数据，有13，34和55的Y值。

Using the ZedGraph control, say I am plotting data that has Y values of 13, 34, and 55.

如何设置我的Y轴，使所示的唯一的文本标签（我猜网格线将同步）是指那些13，34和55？

How do I set up my Y Axis so that the only text labels shown (and I guess that grid lines would be synchronised) are those for 13, 34 and 55?

我不希望在我的数据范围规则间隔的标签（比如0，25，50，75，..）。而就在实际值的标签。

I don't want regularly spaced labels in the range of my data (say 0, 25, 50, 75, ..). Just labels at the actual values.

推荐答案

我不认为这是可能直接，开箱即用。

I don't think it is possible directly, out of the box.

下面是使用自定义TextObj标签，一些较差半的解决方案创建的。

Here's some poor half-solution created using custom TextObj labels.

首先，你需要禁用旧轴规模：

First, you need to disable the old axis scale:

zg1.MasterPane[0].YAxis.Scale.IsVisible = false;
zg1.MasterPane[0].YAxis.MajorTic.IsAllTics = false;

然后，你需要创建自定义标签。如果y_vals是你的Y值的数组：

Then, you need to create custom labels. If y_vals is the array of your Y-values:

foreach (double val in y_vals)
            {
                TextObj text = new TextObj(val.ToString(), zg1.MasterPane[0].XAxis.Scale.Min, val);
                text.Location.AlignH = AlignH.Right;
                text.FontSpec.Border.IsVisible = false;
                text.FontSpec.Fill.IsVisible = false;
                zg1.MasterPane[0].GraphObjList.Add(text); 
            }

您可以只使用LineObj以同样的方式创建自定义的网格线。就在foreach循环里面补充一点：

You can create your custom grid-lines just in the same way using LineObj. Just add this inside the foreach loop:

LineObj line = new LineObj(zg1.MasterPane[0].XAxis.Scale.Min, val, zg1.MasterPane[0].XAxis.Scale.Max, val);
 line.Line.Style = System.Drawing.Drawing2D.DashStyle.Dash;
 line.Line.Width = 1f;
 zg1.MasterPane[0].GraphObjList.Add(line);
