WPF中的方波或脉冲序列 [英] Square wave or pulse train in WPF

问题描述

我们如何在WPF中绘制方波或脉冲序列？我已经在互联网上阅读..但找不到任何解决方案..我发现接近的唯一解决方案是使用正弦函数..这是使用频率...但我没有任何频率...我有一个整数数组..我想从那些整数中绘制方波。因为那些整数代表波浪的过渡状态...



什么我试过了：

how can we draw square wave or pulse train in WPF? I have read on the internet .. but could not find any solution.. the only solution I found that was close was using sine function.. that was using frequency... But i do not have any frequency... i have an array of integers.. and i want to draw square wave from those integers.. As those integers represent the transitional state of the wave...

What I have tried:

Line redLine = new Line();

            redLine.X1 = 100;

            redLine.Y1 = 0;

            redLine.X2 = 200;

            redLine.Y2 = 0;
            SolidColorBrush redBrush = new SolidColorBrush();

            redBrush.Color = Colors.Red;
            redLine.StrokeThickness = 4;

            redLine.Stroke = redBrush;
            myCanvas.Children.Add(redLine);


            Line Line = new Line();

            Line.X1 = 200;

            Line.Y1 = 0;

           Line.X2 = 200;

            Line.Y2 = 150;
            SolidColorBrush Brush = new SolidColorBrush();

          Brush.Color = Colors.Black;
         Line.StrokeThickness = 4;

            Line.Stroke = Brush;
            myCanvas.Children.Add(Line);

            Line line = new Line();

            line.X1 = 200;

            line.Y1 = 150;

            line.X2 = 400;

            line.Y2 = 150;
            SolidColorBrush brush = new SolidColorBrush();

            brush.Color = Colors.Orange;
            line.StrokeThickness = 4;

            line.Stroke = Brush;
            myCanvas.Children.Add(line);

            Line line4 = new Line();

            line4.X1 = 400;

            line4.Y1 = 150;

            line4.X2 = 400;

            line4.Y2 = 500;
            SolidColorBrush brush4 = new SolidColorBrush();

            brush4.Color = Colors.Blue;
            line4.StrokeThickness = 4;

            line4.Stroke = Brush;
            myCanvas.Children.Add(line4);

推荐答案

唯一的解决方案是使用画布。您可以创建一个自定义画布，其中包括创建此类图形的方法。网上有很多例子，显然你看过了。这是一个：

The only solution is to use a canvas. You could possibly create a custom canvas that would include a way to create such a graph. Lots of examples on the web, and obviously you have looked. Here is one:
