Vertical and Horizontal figures on one plot

Question

I would like to create sth like the following graph in matplotlib:

I have x = [0, 1, ..., 10] , and for each x I have values from range [0, 60] . Lets say that the black line is the quantile of values for a given i from range x . For selected i I want to add horizontally histogram (with parameter density = True ) like in the picture with the possibility to control the width of this histogram (in the picture it goes from 2 to 5 but I would like to set fixed width). How can I do that?

Answer 1

Yes, this is relatively straightforward with inset_axes :

import matplotlib.pyplot as plt
import numpy as np

fig, ax = plt.subplots()
x = np.random.randn(100)
ax.plot(x)
ylim = ax.get_ylim()

histax = ax.inset_axes([0.3, 0, 0.2, 1], transform=ax.transAxes)
histax.hist(x, orientation='horizontal', alpha=0.5 )
histax.set_facecolor('none')
histax.set_ylim(ylim)

plt.show()

You will probably want to clean up the axes etc, but that is the general idea.
