Gantt chart
Who is busy when, lane by lane.
Definition · Updated Nov 2, 2026
A Gantt chart puts each resource on its own lane and draws its jobs as bars across the day, with a line for now. Overlaps, gaps and delays show at once. Use it for dock schedules, project plans and room or machine bookings.
Pay once. Every update included.

hello@usechartory.comThe job state: loading, unloading, waiting and delayed, named in the legend. Late jobs also say so in their label (TR-217 · late).
Now, so jobs to its left are done and jobs to its right are to come.
One data object in the sample’s shape: jobs with a lane, a start, an end and a state. The docs page lists every field and links its JSON Schema; the sample data comes with the component, so you can start from it and swap in your own.
Series take the preset’s data colours in order, and states such as up, down or warning take its status colours. Change the preset in Figma or in code to recolour every chart at once.
XS, S, M and L, in light and dark. Each size is laid out again from the data, so text and lines keep their size.
Yes. It plays in when it scrolls into view, and when the data changes every mark moves from its old place to its new one. With reduced motion on, it does not move.
Yes. The React component is free in the public registry in Hearth, no token needed; Signal comes with Code and Complete. The Figma component comes with Figma and Complete.
Ask for it by name. The MCP server tells the agent what data it needs and runs the same command: npx shadcn add @chartory/gantt. You review the diff.
