A Gantt chart is a type of bar chart developed especially for the purpose of illustrating a project schedule - tasks duration, deadlines, dependencies.
Tasks can be viewed as simple list or as Gantt Chart, use the right side "List" tab to switch:
The Gantt charts provide a mechanism for the visual editing of the task schedule. You can use the mouse to change the duration or start and end time or date of a particular task (by simply dragging it in the chart) or set tasks dependencies of 4 main types.
Each task has own start date, end date & deadline.
The task's start date identifies when the task should be started and 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" block, which can be dragged back or forward. In the task creation form the start date can be found under "Time planning option". 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's start date by default.
The task's end date identifies when the task is planned to be finished. It also influences on the deadlines shift scenario for dependent tasks. In the Gantt Chart view the end date is displayed as the end of the task "blue" block, which can be dragged back or forward. In the task creation form the end date can be found under "Time planning option". If the particular end date is not set in the task form then the task "blue" block will be presented in the form of pentagon.
The task's deadline determines the latest date by which the task should be completed. It can be set in the new task form or added in the edit task form later. In the Gantt Chart view the deadline is displayed as "red" block. If the task doesn't have any deadline - there will be no "red" block 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 time panning dates shift
Task's start, end date & deadline can be shifted in the Gantt chart view with the help of the mouse. You can move the task start date or end date back or forward separately (drag the sides of the blue task block) or drag & move the whole task block (the start & end date will be moved together with the task block).
Tasks time tracking & tasks dates shift
By default the tasks time is not tracked, you need to enable this option in the task form first (start time-tracker). In this case when you shift the tasks start & end dates the system will check if the new dates are within the working days & hours (e.g. Mon. - Fr. 09:00 - 18:00) - in this case the tasks dates will be automatically prolonged & shifted to the working days & hours. Working days & hours can be configured by intranet administrator in Intranet Settings.
