ZedGraph设置刻度轴的颜色、刻度文本颜色以及网格线的颜色

1 刻度轴的设置

本小节介绍 如何设置刻度的颜色、长度、生长方向以及将正上方的刻度隐藏掉，还有设置刻度文本的颜色Scale.FontSpec.FontColor。

            Color axisColor = Color.FromArgb(150, 150, 150);
            #region X轴
            //设置主刻度的长度
            this.zedGraph.GraphPane.XAxis.MajorTic.Size = 30f;
            //主刻度颜色  黄色
            this.zedGraph.GraphPane.XAxis.MajorTic.Color = Color.Yellow;
           
            //子刻度颜色   靛青色
            this.zedGraph.GraphPane.XAxis.MinorTic.Color = Color.Cyan;
            this.zedGraph.GraphPane.XAxis.MinorTic.Size = 10f;

            //设置X轴颜色
            this.zedGraph.GraphPane.XAxis.Color = axisColor;
            //设置刻度文本颜色
            this.zedGraph.GraphPane.XAxis.Scale.FontSpec.FontColor = axisColor;
            //设置X轴标题颜色
            this.zedGraph.GraphPane.XAxis.Title.FontSpec.FontColor = axisColor;

            #endregion

如图所示：黄色且比较长的是主刻度，靛青色且较短的是子刻度

看到上方也有刻度的存在，不符合常理，那我们把它隐藏掉吧。设置IsOpposite = false，即可隐藏

            //隐藏X轴正上方的刻度
            //隐藏主刻度
            this.zedGraph.GraphPane.XAxis.MajorTic.IsOpposite = false;
            //隐藏子刻度
            this.zedGraph.GraphPane.XAxis.MinorTic.IsOpposite = false;

接下来设置刻度的朝向，只向里面或只向外边，设置IsOutside或IsInside的属性值。

          //不朝外
          this.zedGraph.GraphPane.XAxis.MajorTic.IsOutside = false;
          this.zedGraph.GraphPane.XAxis.MinorTic.IsOutside = false;

            //不朝里头
           // this.zedGraph.GraphPane.XAxis.MajorTic.IsInside = false;
          //  this.zedGraph.GraphPane.XAxis.MinorTic.IsInside = false;

2 网格线的设置

网格线的设置与刻度轴的设置类似，也有主和次之分。
下面设置Y轴的主网格线为红色，使用点实线绘制，并设置了实线长度为20，虚线（空）的长度为5，子网格线使用蓝色绘制

            //设置网格线 主网格线
            this.zedGraph.GraphPane.YAxis.MajorGrid.IsVisible = true;
            //设置主网格线 为红色
            this.zedGraph.GraphPane.YAxis.MajorGrid.Color = Color.Red;
             
             //实线长度为20
            this.zedGraph.GraphPane.YAxis.MajorGrid.DashOn = 20f;
             //空白长度为5
            this.zedGraph.GraphPane.YAxis.MajorGrid.DashOff = 5f;
            this.zedGraph.GraphPane.YAxis.MajorGrid.PenWidth = 0.1f;
            //子网格线
            this.zedGraph.GraphPane.YAxis.MinorGrid.IsVisible = true;
            this.zedGraph.GraphPane.YAxis.MinorGrid.Color = Color.Blue;
            this.zedGraph.GraphPane.YAxis.MinorGrid.DashOn = 20f;
            this.zedGraph.GraphPane.YAxis.MinorGrid.DashOff = 5f;

3 制作一个好看的背景

上面的颜色是不是太花里胡哨了（主要是为了好区分主次刻度以及其它属性），下面我们做一个黑色色调的，好看一点的。
首先，背景是黑色的；其次，网格线和X轴的刻度都是灰色的；Y轴及Y轴的刻度和文本都是黄色的。

        private void InitPlot()
        {
            //去掉外边框
            this.zedGraph.GraphPane.Border.IsVisible = false;

            //设置黑色
            this.zedGraph.GraphPane.Fill = new ZedGraph.Fill(Color.Black);

            //设置曲线区域的矩形框的颜色  
            this.zedGraph.GraphPane.Chart.Fill = new ZedGraph.Fill(Color.Black);

            //设置绘制曲线区域的矩形框的边框颜色 
              this.zedGraph.GraphPane.Chart.Border.Color = Color.FromArgb(150, 150, 150);

            //灰色
            Color axisColor = Color.FromArgb(150, 150, 150);
            float dashLength = 4f;

            #region X轴
            //设置网格线 主网格线
            this.zedGraph.GraphPane.XAxis.MajorGrid.IsVisible = true;
            this.zedGraph.GraphPane.XAxis.MajorGrid.Color = axisColor;
            this.zedGraph.GraphPane.XAxis.MajorGrid.DashOn = dashLength;
            this.zedGraph.GraphPane.XAxis.MajorGrid.DashOff = dashLength;
            this.zedGraph.GraphPane.XAxis.MajorGrid.PenWidth = 0.1f;
            //子网格线 不可见
            this.zedGraph.GraphPane.XAxis.MinorGrid.IsVisible = false;
            
            //刻度
            //设置主刻度的长度
            this.zedGraph.GraphPane.XAxis.MajorTic.Size = 10f;
            //主刻度颜色 
            this.zedGraph.GraphPane.XAxis.MajorTic.Color = axisColor;

            //隐藏X轴正上方的刻度
            this.zedGraph.GraphPane.XAxis.MajorTic.IsOpposite = false;
            this.zedGraph.GraphPane.XAxis.MinorTic.IsOpposite = false;

            //朝外
            this.zedGraph.GraphPane.XAxis.MajorTic.IsInside = false;
            this.zedGraph.GraphPane.XAxis.MinorTic.IsInside = false;

           
            //设置刻度文本颜色
            this.zedGraph.GraphPane.XAxis.Scale.FontSpec.FontColor = axisColor;
            //设置X轴标题颜色
            this.zedGraph.GraphPane.XAxis.Title.FontSpec.FontColor = axisColor;
            //设置X轴颜色
            this.zedGraph.GraphPane.XAxis.Color = axisColor;

            #endregion

            #region Y轴
            //设置网格线 主网格线
            this.zedGraph.GraphPane.YAxis.MajorGrid.IsVisible = true;
            this.zedGraph.GraphPane.YAxis.MajorGrid.Color = axisColor;
            this.zedGraph.GraphPane.YAxis.MajorGrid.DashOn = dashLength;
            this.zedGraph.GraphPane.YAxis.MajorGrid.DashOff = dashLength;
            this.zedGraph.GraphPane.YAxis.MajorGrid.PenWidth = 0.1f;
            //设置子网格线不可见
            this.zedGraph.GraphPane.YAxis.MinorGrid.IsVisible = false;


            Color ycolor = Color.Yellow;

            //刻度
            //设置主刻度的长度
            this.zedGraph.GraphPane.YAxis.MajorTic.Size = 10f;
            //主刻度颜色 
            this.zedGraph.GraphPane.YAxis.MajorTic.Color = ycolor;
            //设置对面的Y轴刻度不可见
            this.zedGraph.GraphPane.YAxis.MajorTic.IsOpposite = false;

            //朝内
            this.zedGraph.GraphPane.YAxis.MajorTic.IsOutside = false;
            this.zedGraph.GraphPane.YAxis.MinorTic.IsOutside = false;


            //设置Y轴颜色
            this.zedGraph.GraphPane.YAxis.Color = ycolor;
            //设置刻度文本颜色
            this.zedGraph.GraphPane.YAxis.Scale.FontSpec.FontColor = ycolor;
            //设置X轴标题颜色
            this.zedGraph.GraphPane.YAxis.Title.FontSpec.FontColor = ycolor;

            #endregion
        }

设置文本标签的显示方向
默认的Y轴标题是倒着显示的，如何让文本横向显示呢？设置一下Angle 属性。

//设置标题的角度
 this.zedGraph.GraphPane.YAxis.Title.FontSpec.Angle = 90;

4 总结

Axis轴包含一下类，也提供了访问以下类的实例接口：

 MajorGrid: 主网格
 MinorGrid：子网格

 MajorTic： 主刻度
 MinorTic： 子刻度
 Scale：    刻度轴
 Title：      标题
