Suppress Matplotlib's deprecation warning

The warning was:

    coffee-flask/app.py:127: MatplotlibDeprecationWarning:
    normalize=None does not normalize if the sum is less than 1 but
    this behavior is deprecated since 3.3 until two minor releases
    later. After the deprecation period the default value will be
    normalize=True. To prevent normalization pass normalize=False
