For example:

```julia
using UnicodePlots

function func(n)
    r = randn(n)
    s = sum(r)
    hist = histogram(r, nbins=10, closed=:left)
    r, s, hist
end

```

If I call this function in the REPL, it returns:

```julia
julia> func(10)
([1.5369990699727945, -0.7353913882824294, -0.8568141947726255, 1.145149668937184, 0.3340140471550356, 1.2364301576354533, 1.8932925331172032, 0.05768487009000112, -0.2116877502737839, 0.4638080551886433], 4.863485068767476, ┌ ┐
   [-1.0, -0.5) ┤████████████████████████▋ 2
   [-0.5, 0.0) ┤████████████▍ 1
   [ 0.0, 0.5) ┤█████████████████████████████████████ 3
   [ 0.5, 1.0) ┤ 0
   [ 1.0, 1.5) ┤████████████████████████▋ 2
   [ 1.5, 2.0) ┤████████████████████████▋ 2
                └ ┘
                                 Frequency )

```

As seen, the histogram is returned as an element of the tuple, which makes it display sickly. Is there any good solutions to this issue? Thanks.

Doesn’t this do what you want already? If you want to display the histogram separately, do

```julia
julia> r, s, hist = func(10);
julia> hist

```

or

```julia
julia> func(10)[3] 

```
