Avoid overlapping between figure title and axis titles

EDIT

I have finally solved the problem, turns out it was all a bug of the SciView feature in PyCharm, but saving the image as @Bazingaa suggested and adding either of the solutions, i.e. constrained_layout or tight_layout has solved it for me, so the question can be closed. Thanks all for the help :)

QUESTION

I know this question has been asked before, like here and here. However, for some reason, none of the solutions provided has worked for me so far.

I have a figure with two subplots, each of them having its own title and the figure having a title too. The problem is that the title of the figure overlaps with the titles of the axes.

Here is the sample code:

import numpy as np
import matplotlib.pyplot as plt

fig, ax = plt.subplots(1, 2, figsize=(8, 3))
# fig, ax = plt.subplots(1, 2, figsize=(8, 3), constrained_layout=True)

data = np.random.normal(0, 1, 100)

fig.suptitle('Comparison of distribution in different pieces')

ax[0].set_title('Original distributions')
ax[0].hist(x=data, density=True,
           edgecolor='k')

ax[1].set_title('Standardized distribution')
ax[1].hist(x=data, density=True,
           edgecolor='k')

plt.tight_layout()
plt.show()

As you can see I am already using plt.tight_layout(), and I have tried increasing the top margin using plt.adjust_subplots(), and also setting the constrained_layout parameter on the figure to True, but I get exactly the same image no matter how I change the parameters of these functions, or even without calling either of them.

Here is the output image.

Also, any advice or correction regarding this code would be appreciated as I am still a newbie with matplotlib.

P.S. Thanks @Bazingaa for letting me use his code as an example for my problem.

EDIT: Ooops, sorry, didn't read your update.

This works for me:

import numpy as np
import matplotlib.pyplot as plt

fig, ax = plt.subplots(1, 2, figsize=(8, 3), constrained_layout=True)

data = np.random.normal(0, 1, 100)
fig.suptitle('Comparison of distribution in different pieces')


ax[0].set_title('Original distributions')
ax[0].hist(x=data, density=True,
           edgecolor='k')

ax[1].set_title('Standardized distribution')
ax[1].hist(x=data, density=True,
           edgecolor='k')

plt.show()

You can reduce the space used by tight_layout() for the subplots at the top with the rect keyword, e.g.:

plt.tight_layout(rect=[0, 0, 0, .95])

You can specify the y-location for the main title (suptitle) using the y keyword. Below is a sample answer.

import numpy as np
import matplotlib.pyplot as plt

fig, ax = plt.subplots(1, 2, figsize=(8, 3))  # specify figsize later

data = np.random.normal(0, 1, 100)

fig.suptitle('Comparison of distribution in different pieces', y=1.05)

ax[0].set_title('Original distributions')
ax[0].hist(x=data, density=True,
           edgecolor='k')

ax[1].set_title('Standardized distribution')
ax[1].hist(x=data, density=True,
           edgecolor='k')

plt.tight_layout()
plt.show()
