Showing values of points in tooltips and hovering markers

Although a small feature. I think this gives user a better way for seeing and comparing the value instead of showing the value at a fixed position .

Here is an example for the same .


We could also provide value getters for the user for these tooltips . So that they can show different values on hover .

Like if someone wants to see some stats which they don't want to plot but see the values w.r.t to x axis . They could add those in the getters .
