The mouse wheel now zooms a chart only with Ctrl or Cmd held (or a trackpad pinch), so a page of zoomable charts scrolls past them. A bare scroll over a chart shows a short hint instead. Set chart.zoom.allowMouseWheelZoom to true for the old wheel, or chart.zoom.wheelHint to false to hide the hint.
Also about 60 fixes from the rest of the 8.x audit, to bars, stacks, axes, keyboard navigation, treemaps, sunbursts, icicles, unit charts and trellis. A few change behaviour you may rely on:
| Change | What to check |
|---|---|
| Grouped 100% stacks each reach 100% | seriesGroups with 100% |
| Series objects no longer get a group | reads of series.group |
| Numeric xaxis.stepSize sets the step | charts with stepSize |
| Log axes show values below the base | the log axis floor |
| Ragged horizontal numeric bars sit by x | one row per x value |
| Box plots ignore candlestick.type | box plots set to 'ohlc' |
✨ New
- Make the default mouse wheel zoom cooperative.
