使用Matplotlib为子图设置公共xticks（字符串）

Question

给定一组子图，我想为它们设置常见的xticks标签。我知道该怎么做，当蜱数值：

cmap = plt.get_cmap('Set3') 
colors = [cmap(i) for i in numpy.linspace(0, 1, 18)] 

data_1 = numpy.random.rand(18, 7) 
data_2 = numpy.random.rand(18, 7) 
data_3 = numpy.random.rand(18, 7) 
data_4 = numpy.random.rand(18, 7) 

y = range(365) 
plt.figure(figsize=(15,7)) 
for i in range(18): 
    plt.plot(y, data_1[i, :], color=colors[i], linewidth=2) 
    plt.plot(y, data_2[i, :], color=colors[i], linewidth=2) 
    plt.plot(y, data_3[i, :], color=colors[i], linewidth=2) 
    plt.plot(y, data_4[i, :], color=colors[i], linewidth=2) 
plt.setp(axes, xticks=range(7)) 
plt.tight_layout() 

不过，现在我想我的蜱标签是字符串。鉴于此，我想是这样的：

plt.setp(axes, xticks=(range(12), ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday', 'Sunday'])) 

但它不工作：

ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()

谢谢。

如下图所示的例子中可以手动设置你的xticks字符串：

x = [1,2,3,4,5,6,7,8,9,10,11,12] 
y = [1,2,3,4,5,6,7,8,9,10,11,12] 

plt.plot(x,y) 
my_xticks = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'] 

plt.xticks(x, my_xticks) 
plt.show()
