Overlay a line plot and a heatmap in Makie.jl

How can I draw a heatmap in the bg and a line plot over it in Makie.jl?

fig[2, :] = chartgrid = GridLayout(tellwidth=false)

ax = Axis(chartgrid[1, 1])

heatmap!(ax, obc, colormap=:thermal)

lineplot = lines!(ax, plot_series)

What doesn’t work in your code? Your question is a bit vague and I can’t execute your snippet like you posted it :slight_smile:
