Matplotlib for Python Developers - Second Edition

Fine-tuning marker styles with keyword arguments

We can have further refined control over marker styles with some more keyword arguments. For example, for plt.plot(), we can change the markeredgecolor, markeredgewidth, and markerfacecolor.

This is the result of adding the extra keyword arguments:
