Still really struggling to get anything done with glmakie

using GLMakie

points = Observable(Point2f)

push!(points, Point2f(1.0,1.0))

fig = Figure()

ax = Axis(fig[1,1])

scatter(points, markersize = 40)

push!(points, Point2f(1.6,2.2))

notify(points)

Doesn’t update the points on the graph. How should I be controlling a lot of different points? Do i use an array of points? thanks

It works for me, though I had to reset the axis limits to display the new point:

```julia
Makie.reset_limits!(current_axis())

```

or

```julia
on(points) do
  Makie.reset_limits!(current_axis())
end

```
