Gantt Chart Demo

The Gantt Chart demo shows how to create a Gantt component from JSON data.

The data consists of tasks which define the horizontal lanes and activities, each of which is assigned to a task.

An activity has a start and end date, and optionally a lead time and follow-up time. Also an activity can optionally depend on other activities.

The activity duration is rendered as a solid area. The lead and follow-up times are rendered with a hatch pattern.

The activity dependencies are modeled as edges between the activity nodes.

This demo uses Moment.js to parse, manipulate and calculate dates.

Things to Try

Scroll the tasks using the mouse wheel.
Scroll the timeline horizontally using shift + mouse wheel.
Hover over an activity to highlight its dependencies.
Hover over a dependency edge to highlight the source and target.
Select an activity to display the activity information.
Grab and drag an activity to change the start and end time, or to assign an activity to a different task
Grab the left or right side of the solid area of an activity and drag to change the duration.
Select an activity and drag one of the round handles on the left or right to change the lead or follow-up time.
Select an activity and press 'F2' to change its name.
Drag an activity so it overlaps with other activities in the same task lane. The activities are placed below each other so they don't overlap.
Drag the mouse on an empty part of a task lane to create a new activity.
Shift-drag from a node to create a new dependency edge.
