 Step Demo
 =========

 Example step plots.
 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*.
