Giving graphs a subtitle in matplotlib

I want to give my graph a title in big 18pt font, then a subtitle below it in smaller 10pt font. How can I do this in matplotlib? It appears the title() function only takes one single string with a single fontsize attribute. There has to be a way to do this, but how?

What I do is use the title() function for the subtitle and the suptitle() for the main title (they can take different font size arguments). Hope that helps!

The solution that worked for me is:

  • use suptitle() for the actual title
  • use title() for the subtitle and adjust it using the optional parameter y:
    import matplotlib.pyplot as plt
    """
            some code here
    """
    plt.title('My subtitle',fontsize=16)
    plt.suptitle('My title',fontsize=24, y=1)
    plt.show()

There can be some nasty overlap between the two pieces of text. You can fix this by fiddling with the value of y until you get it right.

As mentioned here, uou can use matplotlib.pyplot.text objects in order to achieve the same result:

plt.text(x=0.5, y=0.94, s="My title 1", fontsize=18, ha="center", transform=fig.transFigure)
plt.text(x=0.5, y=0.88, s= "My title 2 in different size", fontsize=12, ha="center", transform=fig.transFigure)
plt.subplots_adjust(top=0.8, wspace=0.3)

In matplotlib use the below function to set the subtitle

fig, ax = plt.subplots(2,1, figsize=(5,5))
ax[0, 0].plot(x,y)
ax[0, 0].set_title('text')
