## 实现 ##

### 添加两条Y轴 ###

ZedGraph是默认带2条Y轴的，所以其自带YAxis属性和Y2Axis属性，

第一条Y轴默认在左边显示,第二条开启后会在右边显示。

开启并设置第二条Y轴。

//第二条Y轴标题
    myPane.Y2Axis.Title.Text = "第二条Y轴标题";
    //第二条Y轴字体
    //myPane.Y2Axis.Title.FontSpec = myFont;
    //让第二条Y轴显示
    myPane.Y2Axis.IsVisible = true;

### 添加更多Y轴 ###

2条以上的Y轴 就要新建后添加到其Y轴的list中去。

// 创建第三条Y轴
                YAxis yAxis3 = new YAxis("第三条Y轴标题");
                //添加到Y轴的list
                myPane.YAxisList.Add(yAxis3);
                //设置刻度线字体颜色
                yAxis3.Scale.FontSpec.FontColor = Color.Green;
                //设置标题字体颜色
                yAxis3.Title.FontSpec.FontColor = Color.Green;
                //设置Y轴颜色
                yAxis3.Color = Color.Green;
                // 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
                yAxis3.MajorTic.IsInside = false;
                yAxis3.MinorTic.IsInside = false;
                yAxis3.MajorTic.IsOpposite = false;
                yAxis3.MinorTic.IsOpposite = false;
                // Align the Y2 axis labels so they are flush to the axis
                //对齐Y2轴标签，使其与轴平齐
                yAxis3.Scale.Align = AlignP.Inside;
    
                // 创建第四条Y轴
                YAxis yAxis4 = new YAxis("第四条Y轴标题");
                //添加到Y轴的list
                myPane.YAxisList.Add(yAxis4);
                yAxis4.Scale.FontSpec.FontColor = Color.Blue;
                yAxis4.Title.FontSpec.FontColor = Color.Blue;
                yAxis4.Color = Color.Blue;
                // turn off the opposite tics so the Y2 tics don't show up on the Y axis
                yAxis4.MajorTic.IsInside = false;
                yAxis4.MinorTic.IsInside = false;
                yAxis4.MajorTic.IsOpposite = false;
                yAxis4.MinorTic.IsOpposite = false;
                // Align the Y2 axis labels so they are flush to the axis
                yAxis4.Scale.Align = AlignP.Inside;

这是创建第三条和第四条Y轴，更多条以此类推。
