Matplotlib: Python plotting — Matplotlib 2.2.2 documentation

• https://matplotlib.org/
• Matplotlib is a Python 2D plotting library which produces publication quality figures in a variety of hardcopy formats and interactive environments across platforms. Matplotlib can be used in Python scripts, the Python and IPython shells, the Jupyter notebook, web application servers, and four graphical user interface toolkits.

matplotlib - Wikipedia

• https://en.wikipedia.org/wiki/Matplotlib
• Matplotlib is a plotting library for the Python programming language and its numerical mathematics extension NumPy. It provides an object-oriented API for embedding plots into applications using general-purpose GUI toolkits like Tkinter, wxPython, Qt, or GTK+. There is also a procedural "pylab" interface based on a state machine (like OpenGL), designed to closely resemble that of MATLAB, though its use is discouraged. SciPy makes use of matplotlib.

Why after calling plt.show() followed by plt.savefig() , the figure is blank ?

• plt.show() should come after plt.savefig()
