View Planned Timeline vs. Actual Timeline in Gannt Chart

Can I compare in Zoho Projects the original timeline projection with the actual timeline of the project in the Gannt Chart?
When I change the dates and times in an already defined project I lose the initial definitions. I would like to be able to see graphically my Planned time vs the Actual time.

See attachment as example. I got that screen from another Project Management tool that has that feature.
That is a very good tool!
