Getting Y value on mouse events

[davifelix5]

Hey everyone!

Does anyone have a workaround for not being able to get the y-value in which a mouse event occurs inside a Cartesian chart?

I want to implement a square area zoom functionality, but I can't seem to make it work because I only have the x-value through the activeLabel parameter, but not the y-value.

I did not find a straighforward way to get the y value based on the coordinate given on the event, but I assume it is possible. Does anyone know how it could be done?
