Step Demo
=========

This example demonstrates the use of `.pyplot.step` for piece-wise constant
curves. In particular, it illustrates the effect of the parameter *where*
on the step position.

The circular markers created with `.pyplot.plot` show the actual data
positions so that it's easier to see the effect of *where*.

.. code-block:: default

    import numpy as np
    import matplotlib.pyplot as plt

    x = np.arange(14)
    y = np.sin(x / 2)

    plt.step(x, y + 2, label='pre (default)')
    plt.plot(x, y + 2, 'C0o', alpha=0.5)

    plt.step(x, y + 1, where='mid', label='mid')
    plt.plot(x, y + 1, 'C1o', alpha=0.5)

    plt.step(x, y, where='post', label='post')
    plt.plot(x, y, 'C2o', alpha=0.5)

    plt.legend(title='Parameter where:')
    plt.show()
