Hi, lingamkss
You could create a Gantt View for your list, by clicking ListTools Ribbon-->List-->Create View-->Choose Gantt View-->Create a
Gantt View.
You could also display this list & view in any webpart page by adding a listview webpart, you can Edit webpart page-->Editing
Tools Ribbon-->Insert-->Existing List-->Add.
Then you could
Edit this webpart and choose created Gantt View as current view, the Gantt Chart would appear on this webpage.
Hope this can help.
Best Regards,
Aaron
