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20this.zedGraph.GraphPane.YAxis.MajorGrid.DashOn = 20f;//空白长度为5this.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
