One date, X values?

Hello there!

I’m currently working on a javascript graph, and I would like to know if it was possible to have more than 1 data for 1 date ?

Actually I have a part of the answer and it’s a yes.

As you can see, there’s 3 dots on 1 date. Thing is I would like to have the information of the 3 dots when I put my mouse on it, and not just one like that:

Is that possible ? Because sometime i’ll have just 2 dots, sometimes 10, sometimes 5 …

Thank you for your help and sorry for my english ;p

If you have any question, feel free to ask! Thanks !
