Gantt chart is a type of bar chart developed especially for the purpose of illustrating a project schedule - tasks duration, deadlines, dependencies.

How it works

Go to Tasks and Projects section > Tasks and select the Gantt view. It is available inside main Tasks section and from Workgroup Tasks as well.

The Gantt chart provides a mechanism for the visual editing of the task schedule using task bars. Each task has own start date, end date & deadline.

• Start date: identifies when the task should be started; it also influences on the deadlines shift scenario for dependent tasks. In the Gantt Chart view the start date is displayed as the beginning of the task "blue" bar, which can be dragged back or forward.
  
  Task start date can be set inside task form in Time Planning section.

  

  If the particular start date is not set in the task form, then the date the task has been created is considered as the task start date by default.
• End date: identifies when the task is planned to be finished. It also influences on the deadlines shift scenario for the dependent tasks. In the Gantt Chart view the end date is displayed as the end of the task "blue" bar, which can be dragged back or forward.
  
  If the particular end date is not set in the task form, then the task "blue" bar will be presented in the form of pentagon.
  
• Deadline: determines the latest date by which the task should be completed. In the Gantt Chart view the deadline is displayed as "red" bar. If the task doesn't have any deadline, there will be no "red" bar displayed in the Gantt Chart view.
  
  If the task is overdue (deadline is earlier the current date), the overdue period will be marked with "red".
  
  Task creator can ban the responsible person from changing the task deadline. Do not tick the Responsible person can change deadline option in task form for this purpose.

  

Tasks time tracking and Workdays

By default, the system does not consider workdays and hours in your company. You need to enable the Skip weekends and holidays option inside the task form first.

In this case when you shift the tasks start and end dates, the system will check if the new dates are within the configured workdays and hours parameters. If not, the tasks dates are automatically shifted forward. Workdays hours can be configured by account administrator in Account Settings.

If you use the Time tracking option, the period when you actually worked on the task will be displayed as a dark thin line in task bar in Gantt chart view.
