Winform中设置ZedGraph多条Y轴时坐标轴左右显示设置

场景

Winform中实现ZedGraph的多条Y轴(附源码下载)：

https://blog.csdn.net/BADAO_LIUMANG_QIZHI/article/details/100132245

在上面实现显示多条自定义Y轴的效果上，效果是左边一条Y轴，第二条在右边显示，然后第三条以及以后都在左边显示。

上面实现的效果

ZedGraph的GraphPane对象的自带YAxis和Y2Axis代表一左一右两个坐标轴对象。

默认显示左边的YAxis对象，右边的Y2Xis需要设置才能显示。

如果要继续添加，在左边则在YAxisList中添加，在右边则在Y2AxisList中添加。

实现

右边显示坐标设置

//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;
// 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);

如果想让坐标轴都显示在左边

// 设置第一条Y轴
myPane = SetYAxisStyle(myPane, yList[0]);
//循环剩下的Y轴
for (int i = 1; i < yList.Count; i++)
     {
        YAxis yAxisNew = new YAxis(yList[i].Title);
        myPane = SetNewYAxisStyle(myPane, yAxisNew, yList[i]);
      }

设置第一条Y轴的方法

public static GraphPane SetYAxisStyle(GraphPane mypane, YAxisModel yAxisModel)
        {
            mypane.YAxis.Title.Text = yAxisModel.Title;
            mypane.YAxis.Title.FontSpec.FontColor = System.Drawing.ColorTranslator.FromHtml(yAxisModel.Color);
            mypane.YAxis.Scale.Min = yAxisModel.Min;
            mypane.YAxis.Scale.Max = yAxisModel.Max;       
            mypane.YAxis.Scale.LabelGap = 0f;
            mypane.YAxis.Scale.Align = AlignP.Outside;
            mypane.YAxis.Scale.FontSpec.Size = Global.FONT_SIZE;
            mypane.YAxis.Color = System.Drawing.ColorTranslator.FromHtml(yAxisModel.Color);
            mypane.YAxis.Title.FontSpec.FontColor = System.Drawing.ColorTranslator.FromHtml(yAxisModel.Color);
            mypane.YAxis.Scale.FontSpec.FontColor = System.Drawing.ColorTranslator.FromHtml(yAxisModel.Color);
            mypane.YAxis.Title.FontSpec.Size = Global.FONT_SIZE;
            mypane.YAxis.Title.FontSpec.Family = Global.FONT_FAMILY;
            mypane.YAxis.Title.FontSpec.IsBold = true;
            mypane.YAxis.Title.IsVisible = false;               //隐藏Y轴标题显示

            #region 刻度设置-小刻度

            mypane.YAxis.MinorGrid.IsVisible = false;          //隐藏小刻度网格线
            mypane.YAxis.MinorTic.IsOpposite = false;          //隐藏对面的刻度-小刻度
            mypane.YAxis.MinorTic.IsInside = false;            //隐藏内测刻度线-小刻度
            mypane.YAxis.MinorTic.IsOutside = true;            //显示外侧刻度线-小刻度
            mypane.YAxis.MinorTic.IsCrossInside = false;       //隐藏内测交叉刻度线-小刻度
            mypane.YAxis.MinorTic.IsCrossOutside = false;      //隐藏外侧交叉刻度线-小刻度

            #endregion

            #region 刻度设置-主刻度

            mypane.YAxis.MajorGrid.IsVisible = true;           //显示主刻度网格线
            mypane.YAxis.MajorGrid.IsZeroLine = false;         //隐藏主刻度的0刻度线
            mypane.YAxis.MajorTic.IsOpposite = false;          //隐藏对面的刻度-主刻度
            mypane.YAxis.MajorTic.IsInside = false;            //隐藏内测刻度线-主刻度
            mypane.YAxis.MajorTic.IsOutside = true;            //显示外侧刻度线-主刻度
            mypane.YAxis.MajorTic.IsCrossInside = false;       //隐藏内测交叉刻度线-主刻度
            mypane.YAxis.MajorTic.IsCrossOutside = false;      //隐藏外侧交叉刻度线-主刻度

            #endregion
            return mypane;
        }

            yAxis.Scale.LabelGap = 0.2f;
            yAxis.Scale.Align = AlignP.Outside;
            yAxis.Scale.FontSpec.FontColor = System.Drawing.ColorTranslator.FromHtml(yAxisModel.Color);
            yAxis.Scale.FontSpec.Size = Global.FONT_SIZE;

            //yAxis.Type = AxisType.Text;               //Y轴不能设置此属性，应该以刻度值显示
            #region 刻度设置-小刻度

            yAxis.MinorGrid.IsVisible = false;          //隐藏小刻度网格线
