Opening the dataset. We need to create a calculated field first
Calculated Field: End DATEADD("day", [Duration], [Start])
Right-click and drag Start to Columns, select continuous Exact Day. Move Task to Rows, change Marks card to Gantt Bar. Drag Resource to Color and Duration to Size
Duplicate Day(Start) on Columns and choose Dual Axis. Don't forget to synchronize axis!
On the first Day(Start) on Marks card, drag End to Text. Drag Start to Text on second one. Edit text and number format as preferred.
You now have a gantt chart demonstrating start and end date for each task.
