为什么 python 的 windrose 绘制错误的值？

Question

我想创建一个只强调风向分布的风玫瑰，所以我将所有风速值设置为相同。我最终的风向和风速数组如下所示：

wd= [10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 30, 30, 30, 30, 30, 30, 30, 30, 30, 30, 30, 30, 30, 30, 30, 30, 30, 30, 50, 50, 50, 50, 70, 70, 70, 70, 70, 70, 70, 70, 70, 70, 70, 70, 90, 90, 90, 90, 90, 90, 90, 90, 110, 110, 110, 110, 130, 130, 170, 170, 170, 170, 170, 170, 190, 190, 190, 190, 190, 190, 210, 210, 210, 210, 210, 210, 230, 230, 250, 250, 270, 270, 270, 270, 270, 270, 270, 270, 270, 270, 270, 270, 270, 270, 270, 270, 290, 290, 290, 290, 290, 290, 290, 290, 290, 290, 290, 290, 290, 290, 290, 290, 290, 290, 290, 290, 290, 290, 290, 290, 290, 290, 290, 290, 290, 290, 290, 290, 290, 290, 290, 290, 290, 290, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 310, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 330, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350, 350]

ws=[6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6]

我在将winddirection数组喂给windrose之前对其进行了归一化处理，上面wd数组中不同winddirection值的个数是这样的（当然是四舍五入到int值）：

10 30.612244897959183
30 18.367346938775512
50 4.081632653061225
70 12.244897959183673
90 8.16326530612245
110 4.081632653061225
130 2.0408163265306123
150 0.0
170 6.122448979591836
190 6.122448979591836
210 6.122448979591836
230 2.0408163265306123
250 2.0408163265306123
270 16.3265306122449
290 38.775510204081634
310 100.0
330 73.46938775510205
350 75.51020408163265

我使用以下命令绘制它：

ax = WindroseAxes.from_ax()
ax.bar(wd, ws,opening=1.0, alpha=0.5, colors='blue',edgecolor='white')

预计风向 310 会显示 100，例如，风向 270 会显示 16。但是，在图中，风向 270 会显示 105，我不知道它来自哪里：

Answer 1

我遇到了同样的问题。在我看来，代码中存在错误。我发现的最佳解决方案是重命名刻度标签，因为情节是正确的。

ax.set_xticklabels(['E', 'NE', 'N', 'NW', 'W', 'SW', 'S', 'SE'])
