1---XAML布局的设计 3层嵌套

2---绘制显示的表格 11x21

for (int i = 0; i <=10; i++)            {                Polyline line = new Polyline();                line.Stroke = new SolidColorBrush(Colors.Red);                Point startPoint = new Point(0,i*30);//起点                Point endPoint = new Point(600,i*30);//终点                line.Points.Add(startPoint);                line.Points.Add(endPoint);                MyCanvas.Children.Add(line);            }            for (int i = 0; i <= 20;i++ )            {                Polyline line = new Polyline();                line.Stroke = new SolidColorBrush(Colors.Red);                Point startPoint = new Point(i*30,0);                Point endPoint = new Point(i*30,600);                line.Points.Add(startPoint);                line.Points.Add(endPoint);                MyCanvas.Children.Add(line);            }

3---根据数据绘制变化曲线

ComSettingModel MyComSettingModel = new ComSettingModel();        private DispatcherTimer tm = new DispatcherTimer();        private PointCollection MyPointCollection = new PointCollection();        private Polyline MyPolyline = new Polyline();        ZigBee MyZigBee;        private void Window_Loaded_1(object sender, RoutedEventArgs e)        {            MyComSettingModel.ZigbeeCom = "COM3";            MyZigBee = new ZigBee(MyComSettingModel);            MyZigBee.Open();            MyPolyline.Stroke = new SolidColorBrush(Color.FromRgb(191, 71, 22));            MainCanvs.Children.Add(MyPolyline);            MyPolyline.Points = MyPointCollection;            //定时器设定            tm.Tick += new EventHandler(tm_Tick);            tm.Interval = TimeSpan.FromSeconds(1.0);            tm.Start();        } int count=0;        void tm_Tick(object sender, EventArgs e)        {               MyZigBee.GetSet();               float temperature =float.Parse( MyZigBee.temperatureValue);               Point pt = new Point(count * 6, 300 - temperature * 6);               MyPointCollection.Add(pt);               if (count <=100)               {                   for (int i = 0; i < MyPointCollection.Count; i++)                   {                       Point npt = new Point(MyPointCollection[i].X, MyPointCollection[i].Y);                       MyPointCollection[i] = npt;                   }                   count++;               }               else               {                   for (int i = 0; i < MyPointCollection.Count; i++)                   {                       Point Line = new Point(MyPointCollection[i].X -6, MyPointCollection[i].Y);                       MyPointCollection[i] = Line;                   }                   count = 100;               }               txtTest.Text = string.Format("变化值:{0}", temperature);            }
