Help : DASH library / How to display the particulars of any point on a graph

Hi everybody, I would like to find a way to display the particulars of any point on a graph when pointing on it.

For instance with the graph below : I need to display the particulars of the black point on the top right :

• either by drawing an horizontal line and a vertical line with the particulars
• or by only displaying the particulars

(nb : the black point doesn’t belong to a list of data, but any zone of the graph)
