If you provide a single list or array to plot, matplotlib assumes it is a sequence of y values, and automatically generates the x values for you. Above, we used import matplotlib.pyplot as plt to import the pyplot module from matplotlib and name it plt. Almost all functions from pyplot, such as plt.plot (), are implicitly either referring to an existing current Figure and current Axes, or creating them anew if none exist.

We will import data files and then plot it and save import matplotlib.pyplot as plt: Matplotlibを使う宣言文: year = [1980, 1985, 1990, 2000, 2010, 2018] 横軸の値、今回は年数。Matplotlibは、リスト化したデータを利用します。 weight = [3, 15, 25, 55, 62, 58] 縦軸の値、今回は体重。データはリストで取り扱います。 plt.plot(year, weight) Matplotlib is the whole package; matplotlib.pyplot is a module in Matplotlib; and PyLab is a module that gets installed alongside Matplotlib. PyLab is a convenience module that bulk imports matplotlib.pyplot (for plotting) and NumPy (for Mathematics and working with arrays) in a single name space.
