Programmatically or interactively???

NB: the doc for interactively includes the following:

Display Data Values Using Data Tips

... To display persistent (pinned) data tips, click one or more data points. ... To pin multiple data tips using the data tips button, hold down the Shift key. ...

Programmatically, you (R2019B and later) use the datatip object and create an array of them...

>> hL=plot(randn(10,1));
>> dt=datatip(hL,'DataIndex',3)
dt = 
  DataTip (X 3, Y 0.282659) with properties:
    DataIndex: 3
     Location: 'northeast'
       Parent: [1×1 Line]
  Show all properties
>> dt(2)=datatip(hL,'DataIndex',6);
>>
