stem

lq.stem(x, y, color=auto, stroke=auto, mark=auto, mark-size=auto, base=0, base-stroke=red, label=none, clip=true, z-index=2)(source)

Creates a vertical stem plot.

#let x = lq.linspace(0, 10, num: 30)

#lq.diagram(
  lq.stem(
    x,
    x.map(calc.cos),
    color: orange,
    mark: "d",
    base: -0.25,
    base-stroke: black,
  )
)

Also see hstem for horizontal stem plots.

Parameters

x : array​

An array of xx coordinates.

y : array | function​

Specifies either an array of yy coordinates or a function that takes an x value and returns a corresponding y coordinate. The number of xx and yy coordinates must match.

color : auto | color    default: auto​

Combined color for line and marks. See also the parameter stem.line which takes precedence over color, if set.

stroke : auto | stroke    default: auto​

The line style to use for this plot (takes precedence over stem.color).

mark : auto | none | lq.mark | str    default: auto​

The mark to use to mark data points. See plot.mark.

mark-size : auto | length    default: auto​

Size of the marks.

base : int | float    default: 0​

Defines the yy coordinate of the base line.

base-stroke : stroke    default: red​

How to stroke the base line.

label : content    default: none​

The legend label for this plot. See plot.label.

clip : bool    default: true​

Whether to clip the plot to the data area. See plot.clip.

z-index : int | float    default: 2​

Determines the zz position of this plot in the order of rendered diagram objects. See plot.z-index.
