Gantt Chart

Hi Tania

Thank you for your question. Generally Gantt charts are created using software rather than physically drawing them. Project scheduling software such as MS Project lets you record your tasks, their durations and sequence and then draws the Gantt chart for you on its calendar. Although initially it's possible to create a similar result in Excel once the project is underway dedicated scheduling software makes it easy to maintain and update the plan.
You can find a description of the process at

I hope this helps - do let us know if you have any further questions.

Kind regards,
Andrew
