说明：  此功能允许创建方向强度直方图，也称为“风玫瑰”。该工具可用于表示这种图形表示。(%% WindRose % Draw a Wind Rose knowing direction and speed % % [figure_handle,count,speeds,directions,Table] = WindRose(direction,speed); % [figure_handle,count,speeds,directions,Table] = WindRose(direction,speed,'parameter1',value1,...); % % figure_handle is the handle of the figure containing the chart % count is the frequency for each speed (ncolumns = nspeeds) and for each direction (nrows = ndirections). % speeds is a 1 by n vector containing the values for the speed intervals % directions is a m by 1 vector containing the values in which direction intervals are centered % Table is a (4+m) by (3+m) cell array (excel-ready), containing Frequencies for each direction and for each speed.)

Java中的Canvas绘图源码实例，主要是画线条、弧线、圆角矩形、三角形、文字、圆形等简单的几何图形，主要是通过创建DrawingCanvas对象canvas，为canvas设置命令监听者，实现接口CommandListener的方法，把缓冲区图像的内容绘制到画布上，画图部分代码： 　　int w = getWidth(); // 画布的宽度 　　int h = getHeight(); // 画布的高度 　　Image buffer = Image.createImage(w, h); // 用于绘图的缓冲图像 　　Graphics gc = buffer.getGraphics(); // 获取缓冲图像的图形环境 　　// 清除画布 　　public void clearScreen() { 　　 gc.setColor(255,255,255); // 设置绘图颜色为白色 　　 gc.fillRect(0,0,w,h); // 把缓冲图像填充为白色 　　 gc.setColor(255,0,0); // 设置绘图颜色为红色 　　} 　　// 绘制直线 　　public void drawLine() { 　　 setTitle("直线"); // 设置画布的标题 　　 clearScreen(); // 清除画布 　　 gc.drawLine(10,10,w-20,h-20); // 绘制黑色直线 　　 gc.setColor(0,0,255); // 设置绘图颜色为蓝色 　　 gc.drawLine(10,h/2,w-10,h/2); // 绘制蓝色直线 　　} 　　// 绘制弧 　　public void drawArc() { 　　 setTitle("弧线和填充弧"); 　　 clearScreen(); 　　 gc.drawArc(5,5,w/2-20,h/2-20,60,216); // 绘制弧线 　　 gc.drawArc(5,h/2-10,w/2-20,h/2-20,0,360); // 绘制圆 　　 gc.setColor(0,0,255); 　　 gc.fillArc(w/2,5,w/2-20,h/2-20,60,216); // 绘制填充弧线 　　 gc

分页工具，用于完成分页功能，使用简单，分页工具(Paging tool, used to complete paging function, easy to use)

说明：  1、单向通信 向甲方连续不断地发送变量a的值，未按键，a=0x0f，按键后根据按键确定a值；并将a的值取反从P0口输出，控制D0、D1、D2、D3相应点亮。乙方接收到数据并偶校验正确后，将接收数据取反从P0口输出，控制D0、D1、D2、D3相应点亮。 2、双向通信 甲方连续不断地发送变量a的值，未按键，a=0x0f，按键后根据按键确定a值；乙方未按键不发送，按键后将乙方按键得到的a*16发送；甲乙双方都将发送数据与接收数据相或后再取反，从P0口输出控制D0—D7相应点亮。 3、间隔发送 未按键，甲方不发送数据，按键后甲方每隔50ms连续发送4个字节：0xff、a、a、a。 乙方只在收到甲方数据0xff后的3个数据并验证相同时，才将接收数据*16发送。 甲乙双方都将发送数据与接收数据相或后，从P0口输出控制D0—D7相应点亮。(1. One-way communication The value of variable a is continuously sent to Party A without key, a = 0x0f. After the key is pressed, the value of a is determined according to the key; and the value of a is output from P0 port to control the corresponding lighting of D0, D1, D2 and D3. After receiving the data and checking it correctly, Party B will output the received data from P0 port and control D0, D1, D2 and D3 to light up accordingly. 2. Two-way communication Party A continuously sends the value of variable a without key, a = 0x0f, and determines a value according to the key after the key; Party B does not send the key without key, and sends the a*16 obtained by the key after the key is pressed; Both parties will send the data to or from the receiving data, and then retrieve the data and control D0-D7 from the P0 port to light up accordingly. 3. Interval Sending Without keys, Party A does not send data. After keys, Party A sends 4 bytes continuously every 50 ms: 0xff, a, a.)
