    # the following functions are defined in example.ipynb 
    line_plot(axes[0, 0])
    scatter_plot(axes[0, 1])

How do I create my own styles?

Have a look at the files qb-common.mplstyle, qb-dark.mplstyle and qb-light.mplstyle. They contain many elements that you may want to customise.

To do so, create a file similar to the above files at the root of your project, and apply it after the qbstyle as follows:

import matplotlib.pyplot as plt
from qbstyles import mpl_style
mpl_style()
plt.style.use('./your-style.mplstyle')
