Inside the callback, get axes CurrentPoint. Extract the x from that and find the closest x in the data. Use that to pull out the strings from the table. Return a cell array of character vectors; each entry will become a separate line in the datatip shown.
I am not going to do an implementation for you, as the result is going to look pretty poor. With that data, I believe that the kind of graph that is being proposed is nearly meaningless.

Load data from excel to matlab using xlsread.
Use this to use labels along the axes:

Use this for dates
