fill-between

lq.fill-between(x, y1, y2=none, stroke=none, fill=auto, step=none, label=none, z-index=2)(source)

Fills the area between two graphs.

#let xs = lq.linspace(-1, 2)
#lq.diagram(
  lq.fill-between(
    xs,
    xs.map(calc.sin),
    y2: xs.map(calc.cos),
  )
)

or the area between one graph and the $x$-axis:

#let xs = lq.linspace(0, 3, num: 80)
#lq.diagram(
  lq.fill-between(
    label: [Maxwell-distribution],
    xs,
    xs.map(x => x*x*calc.exp(-x*x*1.3)),
  )
)

Parameters

x : array

An array of $x$ data coordinates. Data coordinates need to be of type int or float.

y1 : array | function

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

y2 : none | array | function    default: none

An second array (or function) of $y$ data coordinates. If this is none, the area between the coordinates y1 and the $x$-axis is filled.

stroke : none | stroke    default: none

How to stroke the area.

fill : none | color | gradient | tiling    default: auto

How to fill the area.

step : none | start | end | center    default: none

Step mode for plotting the lines. See plot.step.

label : content    default: none

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

z-index : int | float    default: 2

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