The scroll-to-last-tick button now appears as soon as the crosshair is dismissed, instead of staying stale until an unrelated chart rebuild.

With showCrosshair: false, hovering the chart now shows the default cursor instead of the crosshair's precise cursor.

acme_indicatorspub.devPure Dart library for technical analysis computations - RSI, MACD, Bollinger Bands, Ichimoku, and 20+ more indicators with no Flutter dependency.

September 23, 2026

The magnet now snaps drawing points to a candle's nearest OHLC value, not just its time bucket, and marks the captured point with a dot. Off with no candle under the pointer, when repositioning, and for doodles.
Fixed magnet-snapped points landing one bar left of their candle.
A placed measure drawing no longer paints its readout on the canvas; the live label while placing is unchanged.
Trade ratio level lines now render while the second point is being placed, and their labels sit left of each line instead of overlapping it.
HorizontalBarrierStyle takes a lineWidth for dashed and solid lines alike, defaulting to the previous 1.

September 5, 2026

Added Chart.chartTimeConfig for configuring the timezone (utcOffset) used across axis, crosshair, and drawing-tool time labels, instead of always forcing UTC.
Added custom label builder callbacks on ChartTimeConfig for the x-axis and crosshair, so implementors can fully customize the displayed time format (e.g. always show seconds).

September 3, 2026

Added BasicChart.showQuoteGrid / IndicatorConfig.showQuoteGrid: lets an individual pane hide its y-axis quote grid (lines + labels) independently of the shared ChartAxisConfig.showQuoteGrid setting.
Added tap interactivity: BasicChart now detects taps and forwards them to the pane's series via the new Series.onTap(Offset localPosition) method, letting series subclasses handle taps on drawn regions.
Migrated to material_ui.

August 27, 2026

Added Series.axisGroup: an overlay series can now be scaled on its own value range instead of the shared price axis, while still rendering layered over the candles. null (default) shares the main price axis; a non-null value scales independently, and overlay series sharing the same axisGroup value share one combined scale — so unrelated indicators with very different ranges (e.g. a 0-10-bounded oscillator and a MACD-scale signal) don't distort each other.
Fixed MinMaxCalculator treating a NaN entry (e.g. an indicator's not-yet-warmed-up values) as the largest key in its sorted map, silently corrupting Series.maxValue/minValue for the whole visible frame whenever any NaN entry was in view.
Fixed slow, erratic typing when editing "Notes" drawing tool text boxes.

Added new interactive drawing tools: Rectangle, Channel, Notes, Ellipse, Fibonacci Retracement, Fib Fan, Trade Ratio, Doodle, Segment, and Measure.
Added magnet snapping for drawing tools via the new magnetEnabled property on ChartConfig.
Added a copy button for drawings and improved trend line interaction handling.
Updated line and label drawing tool configs to default to blue styling.
Removed unused overlay style JSON serialization methods.

Added StochasticOscillatorIndicatorConfig and its indicator item (Fast/Slow Stochastic Oscillator).
Added FunctionIndicator and MemoizedResult for supplying custom bulk math computations to indicator series.
Exported ChannelFillPainter from chart_series.
Fixed indicator series repaint logic to also honor super.shouldRepaint.
Fixed a null-safety issue where followCurrentTick was checked before confirming width was non-null.
