Silverlight开发历程—（绘制报表）

其本上例子是前台学习的，综合起来做一个报表。很简陋,只是体验一下绘图功能。public partial class ChartFor2011 : UserControl { //创建 坐标集合 private PointCollection pc = new PointCollection(); public ChartFor2011() { InitializeComponent(); LoadLine(); LoadEllipse(); BulidText(); } //创建12个月文本 private void BulidText() { for (int i = 1; i <= 12; i++) { TextBlock txb = new TextBlock() { Text=string.Format("{0}月份",i.ToString()), FontSize=18, Width=40, Foreground=new SolidColorBrush(Colors.White) }; txb.SetValue(Canvas.LeftProperty, pc[i-1].X); txb.SetValue(Canvas.TopProperty, 500.00); canvas_month.Children.Add(txb); } } //使用polyline画线 private void LoadLine() { //将集合添加到集合中 pc.Add(new Point(10,380)); pc.Add(new Point(60, 320)); pc.Add(new Point(110, 365)); pc.Add(new Point(160, 300)); pc.Add(new Point(210, 290)); pc.Add(new Point(260, 320)); pc.Add(new Point(310, 190)); pc.Add(new Point(360, 240)); pc.Add(new Point(410, 150)); pc.Add(new Point(460, 90)); pc.Add(new Point(510, 110)); pc.Add(new Point(560, 40)); Polyline pl = new Polyline(); pl.Stroke = new SolidColorBrush(Colors.White); pl.StrokeThickness = 2; pl.Points = pc; //为PolyLine添加渲染效果 RenderEffect(ref pl); //将对象添加到页面UI上 canvas_chart.Children.Add(pl); } //添加渲染效果 private void RenderEffect(ref Polyline line) { DropShadowEffect dse = new DropShadowEffect(); dse.BlurRadius = 30; dse.Opacity = 1; dse.ShadowDepth = 0; dse.Color = Colors.White; line.Effect = dse; } private void LoadEllipse() { int i = 1; foreach (Point p in pc) { //创建椭圆对象 Ellipse ep = new Ellipse(); ep.Width = ep.Height = 10; ep.Fill = new SolidColorBrush(Colors.Red); ep.VerticalAlignment = VerticalAlignment.Top; ep.HorizontalAlignment = HorizontalAlignment.Left; //计算椭圆位置 double left = p.X - ep.Width / 2; double top = p.Y - ep.Height / 2; ep.Margin = new Thickness(left, top, 0, 0); // 添加信息 ToolTipService.SetToolTip(ep, string.Format("这是{0}月份的数据({1})", i, p.X * p.Y)); canvas_chart.Children.Add(ep); i++; } }
