As mentioned in the earlier comment, stacked bar chart does the trick, though the data needs to be setup differently.(See image below)
Duration column = End - Start
- Once done, plot your stacked bar chart using the entire data.
- Mark start and end range to no fill.
- Right click on the X Axis and change Axis options manually. (This did cause me some issues, till I realized I couldn't manipulate them to enter dates, :) yeah I am newbie, excel masters! :))
