Releases (245)

Patch Changes

• fix(TransformContext): Don't click what a pan, rotate, or pinch is released over (#936)

• fix(Chart): Don't ease an isometric view's angles while dragging (#936)

• fix(Chart): Ease an isometric view added after the chart was created, starting it at its own angles (#936)

Minor Changes

• feat(Contour): Stroke unfilled contours in the bands' colors when no stroke is given (#934)

• feat(Frame|Grid|Axis|Highlight): Draw an isometric chart's back walls, their gridlines (<Grid z>), a height axis (<Axis placement="back">), and highlights at a point's height (#934)

• feat: Support z heights on an isometric chart — boxes (Rect, Cell, Calendar, Bars with valueAxis="z"), floating Circle, Text, Labels and ArcLabel, Line stems, and extruded Polygon, Path, GeoPath, Contour, Pie, Area and Spline (#934)

• breaking(Chart|Spline|Area): Rename the z grouping channel to g (ex. <Spline g="id">), freeing z for a third position (#934)

• feat(TransformContext): Switch mode without remounting the chart (#934)

• feat(Chart): Support view={isometric} to draw the plot area as a floor seen at an angle, turned with isometric({ rotate, tilt }) or by dragging (transform={{ drag: 'rotate' }}), with viewport text facing the viewer (#934)

• feat(Ellipse): Support rotate to turn the ellipse about its center (#934)

Patch Changes

• fix(TransformContext): Zoom in / out about the middle of the plot area, and center a canvas zoom without resetting its scale (#934)

• fix(GeoPath): Start a tweened map shape as itself rather than rising from a baseline (#934)

• fix(Axis): Size an angle axis' ticks by its circle rather than the chart's width, so a continuous angle scale's tick count no longer changes with width (square charts get more ticks) (#934)

• fix(Link): Draw links whose ends share an x or y (#934)

• fix(BrushContext): Draw and measure the brush through a canvas pan / zoom (#934)

• fix(TooltipContext): Account for transform.mode: 'canvas' pan / zoom in bisect modes and 'data' tooltip placement (#934)

Patch Changes

• fix(ArcChart|AreaChart|BarChart|LineChart|PieChart|ScatterChart): Support bind:ref, and bind:context on the .svg / .canvas variants (#930) (#931)

Patch Changes

• fix(Tooltip): Keep a flipped tooltip inside the container (or window) when flipping overflows the other edge (ex. a start-aligned tooltip wider than half a narrow chart opened past its left edge) (#924)

• fix(TooltipContext): Keep a tooltip locked from onclick on touch (a tap's pointerleave precedes click, and its pending hide cleared the data under the lock), and hide it once unlocked if the pointer left while locked (#924)

Minor Changes

• feat(Group|Hull|Rule): Support seriesKey prop to fade the mark while another series is highlighted and remove it while the legend has that series hidden (#917)

Patch Changes

• fix(deps): Bump @layerstack/* dependencies to fix Package subpath is not defined by exports when bundling without Vite (issue #913) (#915)

• fix(Spline): Render startContent, endContent, markerStart, and markerEnd once per line rather than once per style-split segment (#914)

• fix(Spline): Keep the line's color on segments split by a class, opacity, or fill function (#914)

• fix(Spline): Animate segments split by a style function, which motion previously skipped (#914)

Minor Changes

• feat(Axis): Add tickOcclusion to drop ticks whose labels would overlap, measured at the size they render (including rotation), with priority of 'end' (default), 'start', or 'start-end' to choose which survive (#909)

• feat(utils): Add rotate and multiline support to getTextRect, so a rotated or stacked <Text> can be measured for occlude without the caller reproducing <Text>'s pivot (#909)

Patch Changes

• fix(Area): Apply mask, filter, and clip-path to the line path as well as the fill (unless overrideden by line={{...}}) (#909)

• fix(Calendar): Adjust month labels after recent Text verticalAnchor improvements (#909)

• fix(Calendar): Size cells to fit monthPath, which can extend past the last cell when the range ends mid-month (#909)

• perf(Chart): Measure the container before building the subtree, so marks are only built once (#909)

• fix(downloadImage, downloadSvg): Inline stop-color/stop-opacity so gradients don't export as solid black (#909)

• fix(Chart): Return undefined from xGet/yGet when that axis has no accessor, instead of throwing accessor is not a function (#909)

• fix(Spline, Area): Animate each path when the mark is split by z, which motion previously skipped — segments split by a style function are still redrawn outright (#909)

• fix(Path, Spline): Render endContent without a draw transition (#909)

Patch Changes

• perf(Chart): Resolve a plain-key accessor (x="date") directly instead of re-parsing the path string (#906)

• fix(Chart): Treat an explicit but empty series array as authoritative, rather than deriving implicit series from marks (#906)

• perf(Chart): Keep the value domain off the mark registry, so mounting a chart no longer rebuilds its scales — and every path drawn from them — once per mark registered (#906)

• fix(Highlight): Fix crash highlighting c-grouped points over nested chart data (#906)

• fix(Highlight): Mark only the hovered row in quadtree / voronoi tooltips, rather than every row sharing its position (#906)

• feat(Chart): Take the color channel from a mark's own fill / stroke (<Circle fill="island">) when no c is declared (#906)

• fix(Tooltip): Center on internal when data snapping (instead of on its leading edge) (#906)

• fix(Tooltip): Fix persistent tooltip when rendered outside Chart container and pointerEvents is enabled (#906)

Minor Changes

• feat(ChartGroup): Add <ChartGroup> and ChartGroupState to synchronize the tooltip/highlight, brush selection, zoom domain, and series highlight/visibility across charts (#901)

• feat(Chart): Add fx / fy faceting, drawing the chart once per distinct value into a grid of panels that share the position scales (#901)

• feat(Chart): Add seriesLayout="auto" (default) with automatic stacking when applicable (ex. Area, Bars). Can still pass explicit seriesLayout (ex. overlap, group, stack) when needed (#901)

• feat(Bar|Bars): Accept a per-row accessor for fillOpacity, strokeWidth, and opacity, matching Rect and Circle (#901)

• feat(Spline|Area): Resolve stroke, fill, opacity, and class per line/area (and segment). A string naming a data property now resolves through the chart's color scale, like other primitives (ex. Circle) (#901)

• feat(Chart): Default the color scale to the colors declared on series, so marks match their legend swatch (#901)

• feat(Legend): Support ordinal c scale similar to series including highlight and filter capability. An ordinal scale now draws labelled swatches rather than a color ramp — pass variant="ramp" for the old appearance (#901)

• feat(Tooltip): Add tooltip.show({ point, value, data }) to control tooltip programmatically (buttons, keyboard events, etc.) (#901)

• feat: New Brush component to manually position, useful for multiple / independent brushes (ex. parallel coordinates). Also includes new brushable attachment and brushGesture handler for even more granular control of BrushState (#901)

• feat(AnnotationPoint|AnnotationLine|AnnotationRange): Support seriesKey prop to associate an annotation with a series, positioning points and lines on its stacked segment (#901)

• feat(Chart): Add id prop, applied to the root element and identifying the chart within a ChartGroup (#901)

• feat(Rect): Support ref in html layers and forward pointerdown in canvas layers (#901)

• feat(Spline|Area): Add z accessor to draw one line/area per distinct value, defaulting to stroke / fill / c (#901)

• feat(Spline): Support seriesKey prop to follow that series' stacked top (#901)

• feat(Chart): Add transform.initialDomain to open a chart zoomed to a range (#901)

Patch Changes

• fix(BrushContext): Fix clearing on double-clicking the selection (root select-all was immediately undoing) (#901)

• fix(PieChart): Stop drawing a cartesian grid behind the arcs when using series (#901)

• fix(Chart): Stack each x1 sub-band separately, so grouped-and-stacked bars no longer share one running total (#901)

• fix(Chart): Apply zoomToBrush() when called before the chart mounts or when the scale clamps to scaleExtent (#901)

Minor Changes

• feat(TransformContext): Add two-finger pinch-to-zoom (and pan) support on touch devices, along with a new pinch option to disable it (#898)

Patch Changes

• fix(Axis): Support UTC scales (xScale={scaleUtc()}) by filtering and formatting ticks on the same boundaries as the scale (#899)
