#Attributes

On any plane

sizeAnimatable
parametised-number
Distance from the centre to each vertex. The centre sits a quarter of that below the midpoint, so the triangle reads as balanced.
Default1
colourAnimatable
neutralredorangeyellowgreentealbluepurplepinkgreywhiteblack
Also written: colorColour.
Defaultpurple
fillAnimatable
boolean
Fill shape.
Defaulttrue
dashedAnimatable
boolean
Draws the outline dashed — the shape that is not there: a construction, a ghost of a previous position, a region ruled out. As polygon's and segment's.
Defaultfalse
opacityAnimatable
number
Opacity.
Default1
label
rich-text
Text drawn beside the element — rich text, so $maths$ and inline formatting render. Fades and draws with the element.
hiddenAnimatable
boolean
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
boolean
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-sizeAnimatable
number
Text size.
Default20
layerAnimatable
parametised-number
Paint order among the marks: a higher layer is drawn later, on top; equal or omitted, the marks stack in document order (later on top). Written z: before the argand plane took that letter for its coordinate.
Only withxyplane
xImplicitAnimatable
parametised-number
X coordinate.Can be written as shorthand: triangle:value
yAnimatable
parametised-number
Y coordinate.
Only withargandplane
zAnimatable
complex-expression
On the argand plane, the position as one complex number — a complex expression: 3 + 2i, (3 + 2i)^2, sqrt(13) * e^(i * a), with i the unit and parameters read as complex. Instead of re/im.
reAnimatable
parametised-number
On the argand plane, the real part of the position, a number; with im. z: gives both at once.
imAnimatable
parametised-number
On the argand plane, the imaginary part of the position, a number; with re. z: gives both at once.
Only withpolarplane
rAnimatable
parametised-number
On the polar plane, the distance from the origin; with theta.
thetaAnimatable
parametised-number
On the polar plane, the angle anticlockwise from the right, in radians — 60deg writes it in degrees; with r. On a categorical theta (theta format:), a name.
