There is some graph to convert an array

Hello, I have a table with dates, names of people, number of hours worked. I have created a matrix table I see as rows the name, as columns the date values the hours worked. I wanted to show it in a graph where you can see for each worker the hours he has worked each day and the average to see if that day has made more or less hours than the average.

For what purpose can I do it.

Thank you.
