A patch release on top of 6.7.0: three interaction and layout fixes, most importantly a point-selection regression that broke slice clicks on pie and donut charts, plus a new vertical orientation for the unit chart's beeswarm layout. Every existing config renders unchanged.
🐛 Fixes
Clicking a pie or donut slice no longer throws (#5268)
pathMouseDown was bound to the chart instance instead of the Graphics instance that owns _togglePointSelection, so a slice click threw this._togglePointSelection is not a function and selection never toggled. The same mis-binding applied to the mouseenter, mouseleave, mousedown and touchstart listeners on markers, which affected line, area and scatter charts using dataPointSelection. Anything routing through a point click was affected, including drilldown: the "Donut with Drilldown" demo could not be drilled at all on 6.7.0.
Thanks to @andrewbusch7 for the fix (#5252) and to @kne1 for the report.
Semicircle pie, donut and sunburst hug their bottom legend
The fit-to-content branch in Core.resizeNonAxisCharts read its angular span from radialBar's angles regardless of the active chart type, so a pie, donut or sunburst always reported a full 360 and skipped the branch. A semicircle therefore reserved the whole circle's square and left a dead band between the arc and a bottom legend. The span now comes from the active type's own start and end angles, sunburst is included in the selector, and a bottom legend is re-anchored inside the shrunken wrap. Full circles are unaffected.
Sunburst click-to-zoom is interruptible
Clicking a second wedge while the previous zoom was still tweening started a competing animation on the same arcs, and the first zoom's late callback clobbered the second's result, leaving the chart frozen half-zoomed. Superseded frames now stop writing, and an interrupting zoom resumes from each arc's live geometry.
✨ New
Vertical beeswarm orientation for the unit chart
plotOptions.unit.scatter.orientation accepts 'horizontal' (the default) or 'vertical'. Vertical puts the value on the Y axis with category lanes as columns, and the swarm packer now packs along either axis.
plotOptions: {
unit: {
scatter: { orientation: 'vertical' },
},
}The value-axis domain now always contains every datum in both orientations: an explicit xMin / xMax frames the axis and is extended by whole tick steps when data would fall outside it, so a dot is never drawn past the axis where it cannot be hovered.
A new beeswarm sample gallery ships alongside it: body mass by species (vertical), salary by department (horizontal, one CVD-validated hue per team), and a game-scores bubble beeswarm.
