end属性: fig存储图形的句柄。 WindDirections风向数据。 WindFrequency刮风频率。 MaxWindSpeed最大风速数据。 AvgWindSpeed平均风速数据。 RGridThetaGridMinorRGridMinorThetaGrid这些属性用于控制是否显示对应的网格线。 YLabelY轴标签。 还有许多其他的属性例如RGridLineStyleRGridColor等用于控制图形的样式和外观。
方法: 构造函数WindRosePlot当创建WindRosePlot类的对象时此构造函数将被调用。构造函数接收风玫瑰数据作为输入并初始化类的属性。此外还设置了默认的图形样式。 plot方法这个方法用于绘制风玫瑰图。它首先设置坐标轴和极坐标的属性。接下来它会绘制主要和次要的R和Theta网格线。然后它绘制刻度。
