The displayed value of the diagram JS y The axes on the mouse in the diagram relative to the X axis

Question

The displayed value of the diagram JS y The axes on the mouse in the diagram relative to the X axis

In a JS chart, my chart only shows the value when my mouse moves around the chart. I want to display several chart values when my mouse moves around any point on the chart.

This value is for the Y axis relative to the position of the X axis of my mouse (obviously)
