Curve

Stroke width.

Default2

dashed

Dashed stroke.

Defaultfalse

domain

Also written: x-domainRestrict domain.

range

Also written: y-rangeRestrict range.

endpoints

Also written: arrowheads, arrow, arrowhead, arrowsEndpoint decoration: an arrow where the curve runs on past the frame, and a dot where its domain stops it — filled for a closed end, open for an open one. Holes in the function are marked either way.

Defaulttrue

label

rich-text

Text drawn beside the element — rich text, so `$maths$` and inline formatting render. Fades and draws with the element.

hidden

Declared but not drawn. Animatable — `hidden: true !cue.to{false}(at: 2)` reveals it — and unlike a `cue`, a hidden element still frames the plot, so the axes do not jump when it appears.

Defaultfalse

lock

Also written: lockedKeeps the reader from editing this element on an `editable:` graph. Nothing at all on a graph that is not editable.

Defaultfalse

text-size

canvas.graph { }cue { }cue.draw { }cue.trace { }cue.highlight { }cue.spotlight { }

Text size.

Default20

parametised-number

Stacking order. Higher z renders on top; when omitted or equal, elements stack in document order (later on top).

Derived attributes

Computed while the element renders — read one with #id.name in attribute position or !value:#id.name() in prose, never set.

maxDerived

The largest value the expression takes over the curve's effective domain, tracking parameters live.

minDerived

The smallest value the expression takes over the curve's effective domain, tracking parameters live.

Allowed content

Body { }Inline Chalk content (formatted text, inline math, links, and inline elements)

Allowed in

Examples

curve(expression: x^2; colour: blue)

curve(expression: sin(x); domain: [-3.14, 3.14])

Notes

Give a curve a node id — `curve#flight(f: …)` — to let `cue.trace` follow it with `path: #flight`.

Curve

curveBlock elementGraph

A mathematical function or expression plotted as a curve. Supports domain/range restriction for specific intervals.
