How to get multiple timelines on one sheet
Normally, each worksheet has a timeline across the top, and each column represents the same amount of time – a month or a quarter for example. But you can have two timelines on one sheet, where (for example) the first few columns represent months and the rest represent quarters. Openbox calls this a “hybrid” timeline.
To get it, click “Time” then “Settings” and check the “Hybrid timeline” box, as shown below.
