=========
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.

.. note::

    For the common case that you know the edge positions, use `.pyplot.stairs`
    instead.

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

The same behavior can be achieved by using the ``drawstyle`` parameter of
`.pyplot.plot`.
