Semiotic v3.11.2

Added

• band and x-band annotations accept layer: "under" on XY charts
  (including RealtimeHistogram and TemporalHistogram): the fill paints beneath
  the data marks, on the canvas and in static SVG, so bars and areas inside the
  range keep their color, and the label stays above the marks. Bands without
  layer draw above the data as before, as do bands on ordinal, geo, and
  network charts, which ignore layer.
• histogramBinSelectionDatum(timeField) in semiotic/realtime and
  semiotic/utils returns a histogram bin as the chart's own selection
  matching sees it, so useSelection().predicate matches it for any selected
  time inside [binStart, binEnd). Code outside the chart, such as a tooltip
  on the matched bin, can find the bins a linked selection highlights.
• CircularBrush and SentenceFilter accept onObservation (plus
  chartId/chartType, and controlId/controlType on CircularBrush) and
  emit the semiotic/controls control-start, control-change, and
  control-end observations. CircularBrush reports [start, end] for pointer
  drags and keyboard changes; SentenceFilter reports its number and range
  filters, with the filter key as controlId.
• CircularBrush supports Home/End (first and last step of the cycle) and
  PageUp/PageDown (largeStep), shows a focus ring for keyboard focus, and
  focuses the handle you grab.

Fixed

• thresholdBandsForReserve and reserveAnnotationBands classify reserve
  margins from one table, so a mark's style rule and the band behind it agree
  (an 8% margin read "Tight" on the bar and "Watch" on the band). The classes
  follow ReserveLevels as documented: tight < tight, watch
  [tight, watch), moderate [watch, comfortable) (new, info color,
  moderateFill), comfortable ≥ comfortable. The table is exported as
  reserveClasses(levels) and classifyReserve(value, levels) from
  semiotic/recipes, and reserveAnnotationBands takes an optional
  extent for its outer bounds.
• reserveSeries reports netLoadMw as demand minus wind and solar instead
  of repeating demand; gridEventAnnotations no longer stamps a fixed
  confidence: 0.85 on authored events (pass confidence to set one), and
  GridEventWindow.ttlHint documents its actual "P14D" default.
• CircularBrush works for fractional cycles. Pointer values snap to step
  instead of whole units, so a phase brush (period: 1) no longer snaps both
  handles to 0, and period: 24, step: 0.5 brushes half-hours. Without
  step, a period that isn't an integer of 2 or more steps by period / 100
  (integer periods keep 1 and 7). aria-valuemax is the last step before the
  wrap (period - step), and nudges no longer accumulate float noise.
• BigNumber's "duration" format carries rounded remainders into the next
  unit (1m, not 60s; 1h, not 59m 60s; 1d, not 23h 60m), and a
  delta that rounds to zero reads 0 / 0% with neutral sentiment instead of
  +0% or −0 in a success or danger color.
• smartTickFormat, the default axis tick format, moves a value that rounds
  to 1000 of one suffix to the next (1M, not 1000K).
• Default tooltips show the time of intraday Date values (midnight values
  still show the date alone), and the default tooltip value drops
  floating-point noise (0.3, not 0.30000000000000004).
• BumpChart labels Date periods without an xFormat in UTC, at the
  periods' alignment (2024, Mar 2024, Mar 11), instead of the
  machine's locale date, so the browser, renderChart, and the tooltip agree
  in every time zone.
• RealtimeHistogram and TemporalHistogram's default tooltip labels a bin's
  range with the chart's tickFormatTime, or as a UTC date and time for
  epoch-millisecond bins ("Mar 28 10:41–10:42"), instead of raw
  milliseconds. Smaller bounds, such as tick counters, stay numbers.
• RealtimeHistogram and TemporalHistogram hide an axis that showTimeAxis /
  showValueAxis turn off when axes lists only the other one, for example
  axes={[{ orient: "bottom", tickValues }]} with showValueAxis={false},
  in the browser and static SVG. Explicit axes entries still win.
• BumpChart estimates endpoint-label widths per glyph (narrow, wide, capital,
  and wide-script classes at bold sans-serif widths) instead of a flat 0.65em
  per character, so labels that fit are no longer truncated and labeled
  margins stay close to the text. Estimates stay at or above the drawn width
  for Arial, Helvetica, and SF; pin the margin for much wider faces such as
  Verdana.
• GaugeChart string and number centerContent shrinks to fit inside the arc
  when it is too wide for the readout's full size (for example "140 / 200"),
  instead of spilling over the arc. Short values keep their size; the browser
  and static SVG agree.
• wordTrailsLayout sizes words by area (maxFontSize · √(weight / maxWeight)), so a word twice as frequent covers twice the area; before,
  weights 100 and 200 drew at 11px and 42px. minFontSize is now a
  legibility floor, and words raised to it are listed in the result's new
  sizeFloored. A word that finds no free spot is left out and listed in
  unplaced instead of being drawn over another word. Word boxes are measured
  with bold metrics and keep capitals' widths, rotated words collide by their
  rotated bounds, placement is cached by content, and the layout supplies
  restyle, so selection and color/opacity-only changes don't re-run the
  collision search, which now uses a spatial grid.
