Axes: rectangular (ax).

Coordinates

Key	Required	Meaning
x	yes	x positions of the steps
y	yes	y level held until the next x

Style

Key	Type	Purpose
where	string	Step placement: "pre", "post", or "mid"
color	color	Line color
linewidth / lw	float	Line width
linestyle / ls	string	Line style
label	string	Legend label
zorder	number	Draw order

Example

- name: cdf
  data:
    - source: df
      transform: [ {sortby: x} ]
  axes: ax
  method: step
  coordinates:
    x: {expr: x}
    y: {expr: cumulative}
  style:
    where: post
    color: black
    linewidth: 1.0
