I think this was addressed here [How to add grid lines on top of a heatmap in Makie? - #2 by jules](https://discourse.julialang.org/t/how-to-add-grid-lines-on-top-of-a-heatmap-in-makie/77578/2)

So basically just:

```julia
using CairoMakie

fig = Figure()
ax = Axis(fig[1, 1];
	xgridcolor = :white,
	xgridstyle = :dot,
	xgridwidth = 10,
	ygridcolor = :red,
	ygridwidth = 10,
)

hm = heatmap!(ax, rand(5, 5))

translate!(hm, 0, 0, -100)

fig

```
