将plt.plot(x，y)与plt.boxplot()组合 [英] Combining plt.plot(x,y) with plt.boxplot()

问题描述

我正在尝试将普通 matplotlib.pyplot plt.plot(x,y) 与变量 y 作为变量 x 带有箱线图.但是，我只希望在 x 的某些(可变)位置上绘制箱线图，但这在matplotlib中似乎不起作用?

I'm trying to combine a normal matplotlib.pyplot plt.plot(x,y) with variable y as a function of variable x with a boxplot. However, I only want a boxplot on certain (variable) locations of x but this does not seem to work in matplotlib?

推荐答案

您想要这样的东西吗?positions kwarg to boxplot 允许您将箱线图放置在任意位置.

Are you wanting something like this? The positions kwarg to boxplot allows you to place the boxplots at arbitrary positions.

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()
