I am trying to make a graph that is essentially a timeline of a few different activities, all of which can be repeated. The only way I've come up with to do this so far is to have each "instance" of a task graphed as its own series, but then to manually color all the series of the same type in the same color.
Here is an example of a small table and the way I would like the graph it generates to look:
Unfortunately the real table I'm using is quite a bit larger, so it is not practical for me to manually match the color of all series under the same task. I am looking for a way to automatically color each series based on the value in the "Task" column. I am also open to any different way of implementing this that will produce a similar visual result.

I would strongly prefer to accomplish this in Google Sheets, but I do have access to Excel if necessary.
