我对绘制直方图和箱形图Matplotlib有疑问。
我知道我可以分别绘制直方图和箱形图。我的问题是,是否可以将它们绘制在同一图形上,例如本网站中显示的图表? Springer Images
非常感谢你!

有几种方法可以通过matplotlib实现。 plt.subplots()
方法以及AxesGrid1
和gridspec
工具包都提供了非常优雅的解决方案,但可能需要花费一些时间来学习。
一种简单,蛮力的方法是自己将轴对象手动添加到图形。
import numpy as np
import matplotlib.pyplot as plt
# fake data
x = np.random.lognormal(mean=2.25, sigma=0.75, size=37)
# setup the figure and axes
fig = plt.figure(figsize=(6,4))
bpAx = fig.add_axes([0.2, 0.7, 0.7, 0.2]) # left, bottom, width, height:
# (adjust as necessary)
histAx = fig.add_axes([0.2, 0.2, 0.7, 0.5]) # left specs should match and
# bottom + height on this line should
# equal bottom on bpAx line
# plot stuff
bp = bpAx.boxplot(x, notch=True, vert=False)
h = histAx.hist(x, bins=7)
# confirm that the axes line up
xlims = np.array([bpAx.get_xlim(), histAx.get_xlim()])
for ax in [bpAx, histAx]:
ax.set_xlim([xlims.min(), xlims.max()])
bpAx.set_xticklabels([]) # clear out overlapping xlabels
bpAx.set_yticks([]) # don't need that 1 tick mark
plt.show()
