AnyChart Gantt charts support live editing that lets users drag task bars to change dates, resize them to adjust duration, and draw connectors between tasks directly on the timeline.
This sample is a minimal resource Gantt chart with live editing turned on via chart.edit(true). It loads resource allocation data from JSON in table format and calls fitAll to show the complete time span. Users can move and resize resource periods on the timeline, rearrange rows by dragging them in the data grid, and edit cell values inline.
See the Gantt Live Edit documentation for all configuration options.
