    Gantt Charts
    In This Topic

    The Gantt charts are used to represent the schedule of sequence of tasks in a project. To plot Gantt charts, you need to have the start and end times of a task.
    The walkthrough is split into the following activities:


    • This walkthrough uses the ScheduleOfTime table from the Schedule database. The Schedule.mdb can be downloaded from GitHub: ..\Samples15\Data\Reels.mdb.
    • Although this walkthrough uses Page reports, you can also implement this using RDL reports.

    When you complete this walkthrough you get a layout that looks similar to the following at design time and at run time.
