Hello !

I am using GLMakie to vizualise some data :  
fig = Figure()  
ax1 = Axis(fig[1,1])  
lines(space\_sampling,data[:,100])

I would like to be able to go on the plot and to find the values of coordinates for any points using the mouse (as it is possible to do in Matlab). Is it possible?

Thanks 🙂

Hello.

Take a look at `DataInspector`: [Inspecting data](https://docs.makie.org/stable/explanations/inspector).
