The following syntax seems to work fine with both `plotly()` and `gr()`, using `annotate` with automatic bottom alignment.

```julia
using Printf, Plots
x = [1,2,3,4,7]
y = rand(5)
str = [@sprintf("%.2f", yi) for yi in y]
Plots.bar(x,y, title="Annotated bar plot",legend=false)
annotate!(x,y, str, :bottom)

```

_PS: included also a trick shown [here](https://discourse.julialang.org/t/font-of-annotations/14998) to control the annotations’ font size, via tuples. But then the vertical positioning of the labels needs to be refined manually_

```julia
using Printf, Plots
x = [1,2,3,4,7]
y = rand(5)
str = [(@sprintf("%.2f", yi),10) for yi in y] # tuple with fontsize=10 (by: @pdeffebach)
(ymin,ymax) = extrema(y)
dy = 0.05*(ymax-ymin)
Plots.bar(x,y, title="Annotated bar plot",legend=false)
annotate!(x,y.+dy, str, ylim = (0,ymax+2dy))

```
