I found what I really want to realize has been asked in another previous post by myself:

> [@How to let a function return some numerical values and a graph simutaneously?](https://discourse.julialang.org/t/how-to-let-a-function-return-some-numerical-values-and-a-graph-simutaneously/103101):

> For example: 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\> func(10) ([1.5369990699727945, -0.7353913882824294, -0.8568141947726255, 1.145149668937184, 0.3340140471550356, 1.2364301576354533, 1.8932925331172032, 0.05768487009000112, -0.2116877502737839, 0.4638080551886433], 4.863485068767476, ┌ ┐…

In general, I just want a function to output the calculation procedure and then give some conclusive statements (such as displaying the result as a graph), but also the user can easily obtain the result of the function (such as through the most conventional assignment statement).

In fact, I seem to have used some Julia functions (such as some functions for machine learning or optimization) that do have similar effects. 🤔
