基于VC++的风玫瑰图绘制程序设计与实现

Based on VC ++ wind rose drawing program design and implementation

风玫瑰图是用于定量分析风要素重要的专业统计图,被广泛应用于城市规划、环境评价等领域,其绘制过程工作量大、耗时长且易出错。为了有效提高绘图效率、美观度和准确度,开发一款基于VC++的风玫瑰图绘制程序,实现对风要素观测数据进行自动统计和绘制风玫瑰图,具有重要意义。对风玫瑰图概念和程序设计作简要介绍,对程序基础数据导入与处理方法、各方位坐标点的计算和绘制风玫瑰图过程作了详细阐述,并用数据验证了程序绘图效果。

The wind rose diagram is used for quantitative analysis of important factors of wind professional statistical figure , is widely used in fields such as city planning, environmental assessment, large work volume on the drawing process, time-consuming and error-prone.In order to effectively improve the efficiency of drawing, beautiful degree and accuracy, develop a wind rose diagram based on VC＋＋drawing program, realize the factors of the wind observation data for automatic statistics and draw the wind rose, is of great significance.The wind rose, a brief introduction of the concept and the program design of program based data import and processing method, the calculation of coordinates and draw the wind rose diagram in detail in this paper, the process, and data validation program drawing effect.
