将plt.plot(x,y)与plt.boxplot()相结合

Question

我正在尝试将一个普通的matplotlib.pyplot plt.plot(x,y)与变量结合起来作为变量y的函数和xboxplot.但是,我只想在某些(可变)位置上使用boxplot,x但这似乎在matplotlib中不起作用？

你想要这样的东西吗？positionskwarg boxplot允许您将箱形图放置在任意位置.

import matplotlib.pyplot as plt
import numpy as np

# Generate some data...
data = np.random.random((100, 5))
y = data.mean(axis=0)
x = np.random.random(y.size) * 10
x -= x.min()
x.sort()

# Plot a line between the means of each dataset
plt.plot(x, y, 'b-')

# Save the default tick positions, so we can reset them...
locs, labels = plt.xticks() 

plt.boxplot(data, positions=x, notch=True)

# Reset the xtick locations.
plt.xticks(locs)
plt.show()
