铺画列车运行图，可以参考一下如何画线等语句(plot train diagram)

PSCAD的环境下的仿真模型，包含光伏，风机燃气轮机部分对与初学者有很大的借鉴作用(PSCAD environment simulation model, including photovoltaic, wind turbine and gas turbine part of a great reference for beginners)

拟合曲面，先输入已知数据，拟合出系数，再带入未知点的X,Y坐标进行计算！(fitting surface, known to input data, fitting out factor, again into the unknown point of the X, Y coordinates calculated!)

一个简单的程序，可以绘制点、线、圆、方。可以保存成一定格式的图片文件。软件最大的问题是绘图基本在对应的鼠标事件里进行，而没有在paint方法里进行，可借鉴。(A simple program, you can draw points, lines, circles, square. Can be saved into a certain format image files. The biggest problem is the graphics software basic mouse events in the corresponding conduct, but not in the paint method in the conduct, we may learn.)

光立方测试程序,包括各种图形显示，和字符显示(LEDCUDE TEST,SHOW HOW TO MAKE A LED CUBE.)

说明：  DXF文件格式说明，包中包含了dxf文件的所有组码的解释(DXF file format description)

实现绘制5个圆形组成的图案，继承Jpanel类的DrawPanel内部类，并重写paint()方法。(Plotting of five circular pattern composed of inherited Jpanel class DrawPanel inner class, and override paint () method.)

WPF 鼠标拖拽功能，自定义拖拽的跟随图形，不再是一个虚线的系统的小标志，而是具体所拖拽的对象的图形，比如拖一个button，后面跟随的就是一个button的形状。(WPF mouse drag and drop, drag the following custom graphics, broken system is no longer a small sign, but concrete by dragging a graphical object, such as dragging a button, is followed by the shape of a button.)
