你能帮我在下面的极坐标图中为每个轴添加刻度线吗?
这是一张极坐标图的图像,上面有我想要的标记:http://blog.scottlogic.com/archive/2011/09/few.png
这是我当前的情节图,轴上没有刻度线:
这是我正在使用的代码:

rect = [0.05, 0.05, 0.95, 0.95]

self.axes = [fig.add_axes(rect, projection="polar", label="axes%d" % i)
for i in range(self.n)]
self.ax = self.axes[0]
self.ax.set_thetagrids(self.angles, labels=titles,
fontsize=13, weight="normal", color="black")

ax.patch.set_visible(False)
ax.grid("off")
ax.xaxis.set_visible(False)
