Been following this tutorial for creating a repeating task gantt chart. I am having trouble merging all the "subjects" of the y axis under one heading, ie from the pictures above step 2 and step 4 from the tutorial.

This image should explain it better. I want all of the entries under each person for example and I know it probably has something to do with the format axis box. Data is currently set out like 93v92N5.jpg.

Making this started out as a google search out of curiosity and turned into one full day's work of trying to make the chart myself :|

Sorry if I didn't use the correct terms or something too.
