Interface ChartJsScale

Whether the scale runs the other way (largest value at the origin end). A rank axis is the case that matters here: a bump chart reverses y so rank 1 sits at the top.

Chart.js resolves a controller's own default back into chart.options, so this is populated even when the author never wrote it — which is how a matrix chart's y scale reads true off an otherwise bare config.

A category scale's domain, in the order it is drawn along the axis (before ChartJsScale.reverse is applied).

Time-scale options; unit names what one step of the axis measures.

Which axis this scale belongs to; defaults from the scale id's first letter.

Which chart edge the scale is placed against. Chart.js also accepts dynamic positions ('center' or an { [scaleId]: value } object), hence the loose type; only the static edge strings participate in axis stacking.

Axis-stacking group name (Chart.js >= 3.7). Scales of the same axis kind sharing a stack are laid out in separate, non-overlapping bands — the native Chart.js way to express stacked panels within one canvas.

Relative size of this scale's band within its axis stack.
