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- 1

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;- 1

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;- 1

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;- 1

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 }- 1

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;- 1

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- 1
