How to visualize data names in plots with the data cursor

Let's assume that I have 3 functions plotted in the same figure, named 'a', 'b' and 'c'. While I watch the figure I would like to be able to go over one of the functions with the cursor and see its name. Is it possible maybe to change what the "Data cursor" is displaying and add to the coordinates a custom string? Thank you all!

Change the UpdateFcn property of the datacursormode object.

Can you make an example code? Because I read that, but I don't understand how to pass the names that I want to show to that function

I'm also trying to solve the same problem on MATLAB R2019a. I have a figure with many different traces and would to display the name of the trace along with the X and Y coordinates. I found one solution that displays the name but in the command window. Another one that allows you to modify the data tip. However I cant figure how to get the data tip to display the name of the trace. Right now the only way to know is if I creat a legend. The problem is there are a lot of traces and the colors repeat. Thank you!
