I have a stacked bar plot, and can add a label to each block in the stack with `bar_labels=:y`. But this is noisy, and I’d like to only add a single label to the top of the stack, showing the total stacked value. How do I do that?

(here’s an example, borrowed from [Bar Label Alignment · Issue #3160 · MakieOrg/Makie.jl · GitHub](https://github.com/MakieOrg/Makie.jl/issues/3160))

```using

tbl = (x = [1, 1, 1, 2, 2, 2, 3, 3, 3],
       height = 0.1:0.1:0.9,
       grp = [1, 2, 3, 1, 2, 3, 1, 2, 3],
       grp1 = [1, 2, 2, 1, 1, 2, 1, 1, 2],
       grp2 = [1, 1, 2, 1, 2, 1, 1, 2, 1]
       )

barplot(
        tbl.x, tbl.height,
        stack = tbl.grp,
        color = tbl.grp,
        bar_labels = :y,
        axis = (xticks = (1:3, ["left", "middle", "right"]),),
    )

```

I’d like it to show only the labels at the top of each bar, ie “0.6”, “1.5” and “2.4”

thanks!

There’s no inbuilt convenience function to do that, but you can pass a vector of labels to `bar_labels` and you can make all that you want to hide `""`

Perfect!

```julia
using CairoMakie, Makie

tbl = (x = [1, 1, 1, 2, 2, 2, 3, 3, 3],
       height = 0.1:0.1:0.9,
       grp = [1, 2, 3, 1, 2, 3, 1, 2, 3],
       )

barplot(
        tbl.x, tbl.height,
        stack = tbl.grp,
        color = tbl.grp,
        bar_labels = [g==3 ? "$h" : "" for (g,h) in zip(tbl.grp, tbl.height)],
        axis = (xticks = (1:3, ["left", "middle", "right"]),),
    )

```
