Regarding the `arrows!`: I used a bit of a wrong notation for the example I gave in [GLMakie beginners help: Multiple sliders and an arrow - #3 by fatteneder](https://discourse.julialang.org/t/glmakie-beginners-help-multiple-sliders-and-an-arrow/92113/3)  
E.g. I used `xbase, ybase, xhead, yhead`.  
Just took another look at the docstring (try `?arrow` in the `REPL`) and noticed that `arrows` wants arguments like `arrows!(ax1, x, y, u, v)` where `x,y` refer to the base point of the arrow(s) to draw and `u, v` are the directions of the arrow(s) as seen from the base points.

Maybe that helps with clearing up the arrows formulae.
