I suggest you consider using datatips; https://www.mathworks.com/help/matlab/creating_plots/create-custom-data-tips.html
Not all varieties of plotting support the kinds of datatips listed there. For some kinds of plots, see instead datacursormode

i see this example in your link:
p = traccia(1:10);
dtt = p.DataTipTemplate
if p is a struct or class can i catch this reference?
I saw the example and it seems to me that it is only possible to obtain the value of the line at different points but not to capture the reference of the object

I think you might be looking at https://www.mathworks.com/help/matlab/ref/matlab.graphics.datatip.datatiptemplate-properties.html which has the example
p = plot(1:10);
dtt = p.DataTipTemplate
Here plot() is a MATLAB function call that is being asked to work on the data [1,2,3,4,5,6,7,8,9,10] . plot() of a vector returns the handle to a Chart Line object, https://www.mathworks.com/help/matlab/ref/matlab.graphics.chart.primitive.line-properties.html which is an object-oriented object so the variable p would be the reference to the graphics object.
