`graph`

element graph(float | [float] -> value): node

A sparkline with its own history: graph cpu.usage { history: 60s }. Only the new column repaints. Of a value that exists at file scope (a service field, or an expression over service fields, file-level lets, states and settings, and constants) it shows the last history as soon as it mounts, with time asleep as a gap; of one tied to a list item, a component's parameter or let, an element's state or the animation clock, or with a history that is not a constant (a literal, or a file-level let of one), what came since it mounted. A list is several series in one graph, each with its own history, drawn over one another against one range, the first at the back: graph cpu.cores, graph [cpu.usage, memory.usage] { color: $accent, $tertiary }. Its columns are whole periods of the boot clock, the same columns whenever its frames come, and its value does not spring: smooth eases it.

It takes no children.

Also every prop and event of node.

Prop	Type
`history`	`duration`	How much history it keeps and shows (60 s when unset).
`range`	`(float \| auto, float \| auto) \| auto`	The values its bottom and top stand for: `range: 0, 100`; `auto` (or `auto` for one end, `range: 0, auto`) fits what it shows, on a 1, 2, 5 ladder, growing at once and narrowing only once the values shown fit four fifths of a smaller step (0 to 1 when unset). A value outside a fixed range is drawn at its nearer end.
`style`	`GraphStyle`	`line` (a line through its values), `steps` (each value held flat across its column, snapped to whole pixels, with square risers) or `bars` (a bar per value, `line_width` wide and `gap` apart).
`color`	`color \| [color]`	The line's colour (inherited when unset, as every node's), or a list, one per series (taken in turn when there are more series than colours; one colour serves them all).
`fill`	`paint \| [paint]`	The paint under the line, laid over the graph's box (a gradient fades as written: `linear(180deg, $accent.alpha(0.4), $accent.alpha(0))`), or a list, one per series; under `style: bars`, the bars' own paint.
`line_width`	`length`	The line's width (1.5 px when unset); under `style: bars`, each bar's (2 px when unset).
`gap`	`length`	Under `style: bars`, the space between bars (1 px when unset).
`smooth`	`float`	Smoothing: 0 (unset) follows the value; towards 1 each column moves less of the way to it.
