向分组小提琴图添加标签 matplotlib

Question

我在同一轴上有 3 组 3 把小提琴（所以 9 个小提琴图）的图，我想给这些组贴上标签，这是我的尝试：

ax = plt.violinplot([method1[:,0].flatten(),method2[:,0].flatten(),method3[:,0].flatten()],positions= [1,2,3],showmeans=True,showmedians=False)
ax = plt.violinplot([method1[:,1].flatten(),method2[:,1].flatten(),method3[:,1].flatten()],positions=[5,6,7],showmeans=True,showmedians=False)
ax = plt.violinplot([method1[:,2].flatten(),method2[:,2].flatten(),method3[:,2].flatten()],positions=[9,10,11],showmeans=True,showmedians=False)


#positions = (([1,2,3],[5,6,7],[9,10,11]))
#labels = ( "method 1", "method 2","method 3")
#plt.xticks(positions = [2,6,10], labels)

ax.set_xticklabels(['method 1','method 2','method 3'])
ax.set_xticks([2,6,10])

我按预期得到了小提琴图，但我不知道如何添加标签正确。我收到错误：

module 'matplotlib.pyplot' has no attribute 'set_xticklabels'

Answer 1

positions = (2, 6, 10)
labels = ( "m1", "m2","m3")
plt.xticks(positions, labels)
