I have for loop which runs some computation. For debugging, I want to see the output “real-time”. One possible way to do that is continuously plotting add points to the same graph.

```julia
using Gaston
plot(something)
for iter=1:100
    res = myProg(...)
    plot!(res) |> display
end

```

As shown above, I tried to use Gaston to do this. This seems to work, but the use of `plot!(res) |> display` seems strange, as I do not see it in the manual of Gaston.

Could anyone comment on this? Or if you have a better way to plot the results on the fly, please let me know. Thank you!

This is discussed in [Gaston.jl’s package FAQ](https://mbaz.github.io/Gaston.jl/stable/faq/#I-run-plot-inside-a-for-loop-and-no-plots-are-produced!-(or:-Julia's-display-system)-1).

Thank you! Didn’t know this page, which is exactly what I need.
