Gantt overview

Svelte Gantt widget is designed to be easily incorporated into your Svelte application. It provides rich functionality for project management. It enables users to track project progress effectively by its planning and monitoring. It's easy to add, edit, and delete numerous scheduled tasks, set different types of tasks and determine the order of tasks by adding dependencies between them. It's possible to view multiple Gantt charts on one page, add task tooltips and vertical markers making the chart more informative, change relevant data on each project on the fly via the editor form, and even more.

Main UI elements

The Gantt chart illustrates a timeline of a project with its tasks. Its main view consists of the following elements:

• the Tasks tree or Grid area is used for quick navigation and shows each task start date, duration, and has the button control to add a task.

• the Gantt chart where:

  • the timescale shows tasks and other activities by days
  • progress bars represent such task types as projects, tasks, and milestones. Different colors are applied to differentiate between the types.
  • milestones illustrate tasks with zero duration that are used to mark important dates of the project
  • links show dependencies between tasks

• the context menu that opens on the right-click

  

  To open the context menu for a task, right click the required task in the Tasks tree or Gantt chart panel. The menu will open as in the image below:

  

Task types

There are three types of tasks in Gantt chart:

• Task
• Milestone
• Project

The color of the progress bar indicates the task type.

Task

Task is a common task. It has a rectangular shape and a blue color and is usually included into some project.

Milestone

Milestone is a diamond-shaped marker that defines an important point in the workflow. Milestones do not have duration or progress, so you can only specify the start date for them.

Project

Project is a group of tasks, milestones and other projects. It is marked green.
