Helper functions to make animations of images with corresponding traces and labels using matplotlib

-------------

Example uses:

-------------

If you have a 3d movie (time, x, y):

.. code-block:: python

    from Animate.Movie import Movie

    import numpy as np

    m = Movie(dt=1.0 / 14, height_ratio=1.5)

    img = np.random.randint(10, size=(40, 5, 5))

    m.add_image(img, style='dark_img')

    m.add_axis(x_label='time (s)', y_label='value')

    m.add_trace(img.mean(axis=(1, 2)))

    m.save('path/to/file/with_name', fps=1)

.. image:: resources/example.gif

If you have a 2d movie (x, y) where you want to have a sliding window movie:

.. code-block:: python

    import numpy as np

    from Animate.Movie import Movie

    # prepare data

    x_len = 300

    x_res = 20.0

    y_amplitude = 20

    noise_amplitude = 5

    x = np.arange(x_len) / x_res

    y = np.sin(x) * y_amplitude

    pix_number = 10

    img = np.random.randint(0, noise_amplitude, size=pix_number*x_len).reshape(pix_number, x_len) + y

    # make a movie

    rate = 5.0

    m = Movie(dt=1.0/rate)

    m.add_image(img, animation_type='window', window_size=19, window_step=5)

    m.add_axis('Time (s)', 'Mean value')

    m.add_trace(img.mean(axis=0))

    m.save('testing', fps=rate)

.. image:: resources/window.gif
