We don’t have the infrastructure currently to move or copy complex plot objects or axes from figure to figure. But you can write the logic for one of your figures so that you can pass a figure position of another figure to it and plot into that, this way you don’t have to redo any code for the figure itself.
So where you do scatter(f[1, 1]) and f is a Figure it can also be a figure position such as f[2:3, 4]. This gives you a very simple way to do nested figures.
