Shapes

Closed shape marks for a graph environment. They are positioned the same way, take the same attributes and animate identically — the outline is the only difference.

#Members

7 members, differing only in the outline drawn. Each has its own page.

circlecircleA circle centred at (x, y), with size as its radius. One of seven shape marks that differ only in the outline drawn.squaresquareA square centred at (x, y), scaled by size. One of seven shape marks that differ only in the outline drawn.rectanglerectangleA rectangle centred at (x, y), scaled by size. One of seven shape marks that differ only in the outline drawn.triangletriangleA triangle centred at (x, y), scaled by size. One of seven shape marks that differ only in the outline drawn.starstarA five-pointed star centred at (x, y), scaled by size. One of seven shape marks that differ only in the outline drawn.diamonddiamondA diamond centred at (x, y), scaled by size. One of seven shape marks that differ only in the outline drawn.hexagonhexagonA hexagon centred at (x, y), scaled by size. One of seven shape marks that differ only in the outline drawn.

#Shared attributes

Declared identically by every member — defaults included. Anything a member adds on top is on its own page.

On any plane

sizeAnimatable
parametised-number
Radius, in data units.
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: circle: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.
