plot

Draw a line (and/or markers) through a sequence of points. Use it for curves, exclusion limits, and reference lines.

Matplotlib: Axes.plot. Coordinates are forwarded as plot(x, y, ...). A format string can be supplied via style.fmt (e.g. "r--").

Axes: rectangular (ax) and ternary (axtri).

Coordinates

Key	Required	Meaning
x	yes	x positions (sorted along the curve)
y	yes	y positions

Style

Key	Type	Purpose
fmt	string	Matplotlib format string, e.g. "r--", "k.-"
color	color	Line color
linewidth / lw	float	Line width
linestyle / ls	string	"-", "--", "-.", ":"
marker	string	Marker at each point
markersize / ms	float	Marker size
alpha	0–1	Opacity
label	string	Legend label
zorder	number	Draw order

Any other Axes.plot keyword is also accepted.

Example

- name: exclusion_curve
  data:
    - source: limit_curve
      transform: [ {sortby: x} ]    # plot expects points ordered along x
  axes: ax
  method: plot
  coordinates:
    x: {expr: x}
    y: {expr: y}
  style:
    color: red
    linestyle: "--"
    linewidth: 1.5
    label: "95% CL"
    zorder: 40

Notes

• plot connects points in row order — sort the data first if the curve should be monotonic.
• For a filled region under/around a curve, see fill or fill_between.
