WindDirections:風(fēng)向數(shù)據(jù)。
WindFrequency:刮風(fēng)頻率。
MaxWindSpeed:最大風(fēng)速數(shù)據(jù)。
AvgWindSpeed:平均風(fēng)速數(shù)據(jù)。
RGrid,ThetaGrid,MinorRGrid,MinorThetaGrid:這些屬性用于控制是否顯示對應(yīng)的網(wǎng)格線。
YLabel:Y軸標簽。
還有許多其他的屬性,例如RGridLineStyle,RGridColor等,用于控制圖形的樣式和外觀。
方法:構(gòu)造函數(shù)WindRosePlot:當創(chuàng)建WindRosePlot類的對象時,此構(gòu)造函數(shù)將被調(diào)用。構(gòu)造函數(shù)接收風(fēng)玫瑰數(shù)據(jù)作為輸入,并初始化類的屬性。此外,還設(shè)置了默認的圖形樣式。
plot方法:這個方法用于繪制風(fēng)玫瑰圖。它首先設(shè)置坐標軸和極坐標的屬性。接下來,它會繪制主要和次要的R和Theta網(wǎng)格線。然后,它繪制刻度。
