先看展示效果

1.创建曲线实例添加必要的元素

 1 public class lineChannel 2     { 3         public lineChannel(int ID,int number,string name,string type,bool selected,color linecolor,int linewidth) 4         { 5             this.ID = ID; 6             this.number = number; 7             this.name = name; 8             this.type = type; 9             this.selected = selected;10             this.linecolor = linecolor;11             this.linewidth = linewidth;12         }13 14         private int ID;15         private int number;16         private string name;17         private string type;18         private bool selected;19         private color linecolor;20         private int linewidth;21 22         23         public int ID24         {25             get { return this.ID; }26             //set { this.ID = value; }27         }28 29         public int Number30         {31             get { return this.number; }32         }33 34         public string name35         {36             get { return this.name; }37             //set { this.name = value; }38         }39 40         public string Type41         {42             get { return this.type; }43             //set { this.type = value; }44         }45         public bool Selected46         {47             get { return this.selected; }48             set { this.selected = value; }49         }50         public color linecolor51         {52             get { return this.linecolor; }53             set { this.linecolor = value; }54         }55         public int linewidth56         {57             get { return this.linewidth; }58             set { this.linewidth = value; }59         }60 61     }

2.初始化控件增加曲线

全局曲线和其实时间保存

   private List<lineChannel> lines;   //所有的曲线   private int tickStart = 0;     // 起始时间以毫秒为单位

初始化曲线

 1   //加载创建曲线数据 2             lineChannel lineChannel1 = new lineChannel(1111,1,"曲线 1","温度",true,color.Red,1); 3             lineChannel lineChannel2 = new lineChannel(2222,2,"曲线 2",color.Green,1); 4             lineChannel lineChannel3 = new lineChannel(3333,3,"曲线 3",color.Gray,1); 5             lineChannel lineChannel4 = new lineChannel(4444,4,"曲线 4",color.Black,1); 6  7             this.lines.Add(lineChannel1); 8             this.lines.Add(lineChannel2); 9             this.lines.Add(lineChannel3);10             this.lines.Add(lineChannel4);11 12 13             //获取引用14             GraPHPane myPane = zedGraphControl1.GraPHPane;15             //设置标题16             myPane.Title.Text = "实时曲线";17             //设置X轴说明文字18             myPane.XAxis.Title.Text = "时间";19             //设置Y轴说明文字20             myPane.YAxis.Title.Text = "温度";21 22 23             //添加曲线24             foreach (lineChannel channel in this.lines)25             {26                 RollingPointPairList List = new RollingPointPairList(1200);27                 lineItem curve = myPane.AddCurve(channel.name,List,channel.linecolor,SymbolType.None);28             }29 30 31             int increment = 30;//单位s32 33 34 35 36             myPane.XAxis.Scale.Min = 0; //X轴最小值037             myPane.XAxis.Scale.Max = 30; //X轴最大3038             myPane.XAxis.Scale.MinorStep = 1;//X轴小步长1,也就是小间隔39             myPane.XAxis.Scale.MajorStep = 5;//X轴大步长为5，也就是显示文字的大间隔40 41             //改变轴的刻度42             zedGraphControl1.AxisChange();43             this.zedGraphControl1.InvalIDate();44             this.dataGrIDVIEwlines.DataSource = this.lines;45             this.dataGrIDVIEwlines.ClearSelection();

3.增加线程处理 模拟数据

 1   //保存开始时间 2             tickStart = Environment.TickCount; 3             stop = false; 4             BackgrounDWorker worker = sender as BackgrounDWorker; 5  6             isSampling = true; 7             List<lineChannel> channels = this.lines; 8             //DoWork 9             lineData lineData;10             while (isSampling)11             {12                 lineData = new lineData();13 14 15                 //获取数据16                 double time = (Environment.TickCount - tickStart) / 1000.0;17                 double data = Math.Sin(2.0 * Math.PI * time / 3.0);18                 double data2 = data - 0.4;19                 double data3 = data - 0.8;20                 double data4 = data - 1.2;21 22                 //添加数据23                 lineData.Add(channels[0],time,data);24                 lineData.Add(channels[1],data2);25                 lineData.Add(channels[2],data3);26                 lineData.Add(channels[3],data4);27 28                 //上报数据处理29                 worker.ReportProgress(0,lineData);30 31                 Thread.Sleep(50);32             }

4.数据接受更新曲线

 1 lineData lineData = e.Data; 2  3             double time = 0,data = 0; 4  5             foreach (lineChannel channel in lineData.Channels) 6             { 7                 if (e.Data.GetData(channel,out time,out data)) 8                 { 9                     lineItem curve = null;10 11                     foreach (var item in zedGraphControl1.GraPHPane.CurveList)12                     {13                         if (item.Label.Text == channel.name)14                             curve = item as lineItem;15                     }16 17                     if (curve != null)18                     {19                         IPointListEdit List = curve.Points as IPointListEdit;20                         List.Add(time,data);21                     }22 23                     curve.IsVisible = channel.Selected;24                     curve.line.WIDth = channel.linewidth;25                     curve.line.color = channel.linecolor;26 27 28                 }29 30 31             }32 33 34             Scale xScale = zedGraphControl1.GraPHPane.XAxis.Scale;35             if (time > xScale.Max - xScale.MajorStep)36             {37                 xScale.Max = time + xScale.MajorStep;38                 xScale.Min = xScale.Max - 30.0;39             }40 41 42             //if (time > xScale.Max)43             //{44             //    xScale.Max = time;45             //    xScale.Min = xScale.Max - 30;46             //}47 48 49             //第三步:调用ZedGraphControl.AxisChange()方法更新X和Y轴的范围50             zedGraphControl1.AxisChange();51 52             //第四步:调用Form.InvalIDate()方法更新图表53             zedGraphControl1.InvalIDate();
