## 实现 ##

主窗体添加按钮，点击之后弹出Y轴设置界面。

private void button12_Click(object sender, EventArgs e)
            {
                addY = new AddY();
                addY.Show();
    
            }

其中addY是对应要弹窗显示的窗体对象，其设计如下

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70][]

此窗体有两个EditText，用来存储Y轴的上下限，然后使用RadioGroup用来设置标题的选择，然后使用

ColorEditPicker进行颜色的选择，以上的控件都是使用的DevExpress的控件。

在点击新增按钮时将控件上的所有属性赋值给声明的YAxis对象。

private void button1_Click(object sender, EventArgs e)
            {
                YAxis y = new YAxis();
                //标题
                y.Title.Text = this.radioGroup1.Text;
                //颜色
                y.Color = this.colorPickEdit1.Color;
                //下限
                y.Scale.Min = Double.Parse(this.textEdit1.Text);
                //上限
                y.Scale.Max = Double.Parse(this.textEdit2.Text);
    
                if (setYaxisEvent != null)
                {
                    setYaxisEvent(y);
                }
              
            }

这里使用的是事件与委托进行跨窗体传递对象。

在AddY当前页面代码中

//委托的定义
    public delegate void SetYaxisDelegete(YAxis s);
    //事件声明
    public static event SetYaxisDelegete setYaxisEvent;

然后在主页面Form1中的初始化方法中进行委托的订阅

//添加Y轴
    AddY.setYaxisEvent += new AddY.SetYaxisDelegete(addYaxis);

此时传递了addYaxis方法名

方法代码：

public void addYaxis(YAxis y)
            {
                //如果是新增第二条Y轴
                if (ycount == 1)
                {
                    //第二条Y轴标题
                    myPane.Y2Axis.Title.Text = y.Title.Text.ToString();
                 
                    //第二条Y轴下限
                    myPane.Y2Axis.Scale.Min = y.Scale.Min;
                    //第二条Y轴上限
                    myPane.Y2Axis.Scale.Max = y.Scale.Max;
                    //设置颜色
                    myPane.Y2Axis.Color = y.Color;
                    //设置刻度线字体颜色
                    myPane.Y2Axis.Scale.FontSpec.FontColor = y.Color;
                    //设置标题字体颜色
                    myPane.Y2Axis.Title.FontSpec.FontColor = y.Color;
                    //让第二条Y轴显示
                    myPane.Y2Axis.IsVisible = true;
                    ycount++;
                    //关闭窗口
                    addY.Close();
                    zedGraphControl1.Invalidate();
                   
                }
                //否则就是新增第三条及以上
                else
                {
                    //int yIndex = myPane.YAxisList.Count+1;
                    // 创建第yIndex条Y轴
                    YAxis yAxisNew = new YAxis(y.Title.Text.ToString());
                    yAxisNew.Scale.Min = y.Scale.Min;
                    yAxisNew.Scale.Max = y.Scale.Max;
                    //设置Y轴颜色
                    yAxisNew.Color = y.Color;
                    //设置刻度线字体颜色
                    yAxisNew.Scale.FontSpec.FontColor = y.Color;
                    //设置标题字体颜色
                    yAxisNew.Title.FontSpec.FontColor = y.Color;
                    //yAxisNew.Type = AxisType.Text;
                    //显示小刻度 是false则看不到效果
                    //yAxisNew.MinorGrid.IsVisible = true;
                    // turn off the opposite tics so the Y2 tics don't show up on the Y axis
                    //关闭相反的tics，使y2 tics不会显示在y轴上
                    yAxisNew.MajorTic.IsInside = true;
                    yAxisNew.MinorTic.IsInside = true;
                    yAxisNew.MajorTic.IsOpposite = true;
                    yAxisNew.MinorTic.IsOpposite = true;
                  
                 
                    // Align the Y2 axis labels so they are flush to the axis
                    //对齐Y2轴标签，使其与轴平齐
                    //yAxisNew.Scale.Align = AlignP.Inside;
                    //添加到Y轴的list
                    myPane.YAxisList.Add(yAxisNew);
                    //关闭窗口
                    addY.Close();
                    zedGraphControl1.Invalidate();
                }
            }
