"""
`matplotlib.pyplot` is a state-based interface to matplotlib. It provides
a MATLAB-like way of plotting.

pyplot is mainly intended for interactive plots and simple cases of
programmatic plot generation::

    import numpy as np
    import matplotlib.pyplot as plt

    x = np.arange(0, 5, 0.1)
    y = np.sin(x)
    plt.plot(x, y)

The object-oriented API is recommended for more complex plots.

Since this subplot will overlap the # first, the plot (and its axes) previously created, will be removed plt.subplot(211) If you do not want this behavior, use the `.Figure.add_subplot` method or the `.pyplot.axes` function instead. If the figure already has a subplot with key (*args*, *kwargs*) then it will simply make that subplot current and return it. This behavior is deprecated. Meanwhile, if you do not want this behavior (i.e., you want to force the creation of a new subplot), you must use a unique set of args and kwargs. The axes *label* attribute has been exposed for this purpose: if you want two subplots that are otherwise identical to be added to the figure, make sure you give them unique labels. In rare circumstances, `.add_subplot` may be called with a single argument, a subplot axes instance already created in the present figure but not in the figure's list of axes.
