## 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][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;
            }

设置新增Y轴的方法

public static GraphPane SetNewYAxisStyle(GraphPane myPane, YAxis yAxis, YAxisModel yAxisModel)
            {
                yAxis.Title.Text = yAxisModel.Title;
                yAxis.Title.FontSpec.FontColor = System.Drawing.ColorTranslator.FromHtml(yAxisModel.Color);
                yAxis.Scale.Min = yAxisModel.Min;
                yAxis.Scale.Max = yAxisModel.Max;         
                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.Scale.FontSpec.FontColor = System.Drawing.ColorTranslator.FromHtml(yAxisModel.Color);
                yAxis.Color = System.Drawing.ColorTranslator.FromHtml(yAxisModel.Color);
                yAxis.Title.FontSpec.FontColor = System.Drawing.ColorTranslator.FromHtml(yAxisModel.Color);
                yAxis.Title.FontSpec.Size = Global.FONT_SIZE;
                yAxis.Title.FontSpec.Family = Global.FONT_FAMILY;
                yAxis.Title.FontSpec.IsBold = true;
                yAxis.Title.IsVisible = false;              //隐藏Y轴标题
                //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
                yAxis.MinorTic.IsOpposite = false;          //隐藏对面的刻度-小刻度
                yAxis.MinorTic.IsInside = false;            //隐藏内测刻度线-小刻度
                yAxis.MinorTic.IsOutside = true;            //显示外侧刻度线-小刻度
                yAxis.MinorTic.IsCrossInside = false;       //隐藏内测交叉刻度线-小刻度
                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
    
                yAxis.MajorGrid.IsVisible = true;           //显示主刻度网格线
                yAxis.MajorGrid.IsZeroLine = false;         //隐藏主刻度的0刻度线
                yAxis.MajorTic.IsOpposite = false;          //隐藏对面的刻度-主刻度
                yAxis.MajorTic.IsInside = false;            //隐藏内测刻度线-主刻度
                yAxis.MajorTic.IsOutside = true;            //显示外侧刻度线-主刻度
                yAxis.MajorTic.IsCrossInside = false;       //隐藏内测交叉刻度线-主刻度
                yAxis.MajorTic.IsCrossOutside = false;      //隐藏外侧交叉刻度线-主刻度
    
                #endregion
    
                //添加到Y轴的list
                myPane.YAxisList.Add(yAxis);
                return myPane;
            }
