Arc Diagram - A new chart type that shows connections between items: nodes are placed on one line, and links are drawn as arcs whose thickness shows the link value.
Dependency Wheel - A new chart type that shows flows between items: nodes are arcs around a circle, and links are bands between them whose thickness shows the flow.
Organizational Chart - A new chart type that shows a hierarchy as a tree of cards joined by connector lines, with collapsible branches, zoom and pan.
Stream Graph - A new chart type that shows how parts of a whole change over time: area layers are stacked around a moving baseline instead of a flat zero line.
Waffle Chart - A new chart type that shows parts of a whole as a grid of cells, where each category takes a block of cells matching its share.
Dumbbell Series - A new series that shows two values per category as two markers joined by a line. Available on cartesian and stock charts.
Lollipop Series - A new series that draws each value as a thin stick from the baseline with a marker at its end. Works on cartesian and stock charts.
Data Sheet - A new grid component for tabular data, with sorting, grouping, filtering, cell editing and export to CSV and JSON.
Boost Mode for Large Data - Boost mode draws large series on Canvas or WebGL instead of SVG. It turns on automatically for a single large series, or on request.
Accessibility - Many chart types now label each point for screen readers and support keyboard navigation between points. A high-contrast palette can be switched on globally.
Themes and Palettes - Themes can now be loaded on demand with one call, and the built-in palettes can be applied by name.
Improvements:
Range series can show a label at each end, each with its own settings.
Label overlap control is now available on all cartesian series.
Sankey Diagram nodes, flows and dropoffs now support hatch fills.
Network Graph: The minimum and maximum zoom can be set, and panning can be limited to the chart area.
Crosshair: A new mode snaps the vertical line to the nearest point.
Calendar charts can now grow to fit their content.
Modules can now be loaded at run time, without a script tag.
Breaking changes:
Client-side export no longer falls back to the export server by default; enable the fallback option to restore it.
With multi-select on click enabled, a Shift-click on a selected point now deselects it.
Network Graph: A Shift-click now adds to the selection instead of replacing it.
Network Graph: Zoom set from code is now limited to the zoom bounds.
Replacing the data of a series now clears its hover and selection state.
Candlestick series now apply hatch fill settings, which were ignored before.
The Bower package is no longer published; install from npm or the CDN.
修正
Charts drawn after the page body was cleared or replaced no longer have misplaced titles and labels.
Stacked spline-area charts with a missing first point no longer crash or draw blank.
Crosshair in sticky mode no longer causes an error when no point is near the cursor.
Sankey Diagram no longer crashes on data with cycles or self-links.
A theme applied after a sparkline, treemap, sunburst, PERT or resource chart was created now applies to the charts created later.
Stacked area series with connected missing points no longer break the layers above a gap.
A stacked chart with only empty series no longer causes an error.
Heat Map cells without a numeric value are drawn as no-data cells without a label.
Disposing a Timeline chart immediately after drawing no longer causes an error.
