Hello everyone!

First of all, it's been a while since i posted anything (Few years actually), so if i missed the thread, mod can freely move it to an appropriate one

The problem i'm having is with Excell's Gantt diagram. I need to create one for my school's project, and i have no idea on how do i do this.
However, it's not the "Usual" one - I can handle that one. The gimmick enters the play when i need to insert a 2nd value in it - The look on how it should be when completed is something like this (Please don't mind the language): https://cdn.pbrd.co/images/2nbNpJhd.png

In this case, the red line represents a single worker on an assembly line, while the blue one is a 2nd worker who's doing the parallel activities along the first one.

Any idea on how can i create something, at least, similar to this? It would really help me a lot, since google didn't (Or i'm in some kind of a full-retard mode).

Best regards,

Mirodjija
