Ok, I used this SetTooltip instead of beginTooltip which I usually use and it works.

```julia
if CImGui.IsItemHovered()
    region_x = Cint(div(length(x)*(io.MousePos.x - pos.x),img_width)+1)
    CImGui.SetTooltip(@sprintf("X = %g m \n B = %.2f", x[region_x], Bplane[region_x]))
end

```

Thank you. Still have problem with Greek characters, if you could help, here’s my other problem [CImGui Greek Characters](https://discourse.julialang.org/t/cimgui-greek-characters/28918).
