运行出现错误
在这里插入图片描述

Exception has occurred: ValueError
The number of FixedLocator locations (7), usually from a call to set_ticks, does not match the number of ticklabels (6).
  File "D:\ex\HollandRadarDraw.py", line 25, in <module>
    plt.thetagrids(angles*180/np.pi, radar_labels, frac=1.2)

经查找,是matplotlib的版本问题,删掉
在这里插入图片描述
运行,出现错误
在这里插入图片描述

Exception has occurred: AttributeError

    plt.thetagrids(angles*180/np.pi, radar_labels, frac=1.2)

删掉‘frac=1.2’
运行成功
