Unable to add multiple plots to a single scene in Makie

I am new to Makie and Julia in VSCode and I am trying to plot two plots in one scene. My code is

using Makie, GLMakie

GLMakie.activate!()
Makie.inline!(true)


x = rand(100)
y = rand(100)
z = rand(100)

scene = scatter(x, y, color=:forestgreen, markersize=7.5)
scene = scatter!(y, z, color=:crimson, markersize=7.5)

The first time (when I call scatter) my code evaluates to a FigureAxisPlot() and I get a plot on the side. But the second time (when I call scatter!) my code evaluates to a Scatter{Tuple{Vector{Point{2, Float32}}}} and the plot doesn’t change and a new plot is not created. I am following the Julia for the Talented Amateur series, and this code seems to work for them. I’m not sure how to fix it.

I am running Julia 1.8 on a Mac in VSCode and I ran up in the pkg> prompt so I believe all the packages are updated to the latest versions.

Check out the basic tutorial in the docs :slight_smile: Basic Tutorial

Scene used to be the return value of plotting functions quite a long time ago, I assume the tutorial you followed was made in that era.

Oh okay, thank you! The tutorial was from Nov 2020 so I didn’t think things could change that fast, but it is good to know.

I quickly checked and we released this in January 2021 [ANN] Makie Update: Figures And Integrated Layouts

Two years is a long time for us :slight_smile: Obviously not a lot in terms of absolute time, but many many things changed in this package along the way. I know it’s annoying to find outdated teaching material, but often these breaking changes were just very necessary so we don’t get stuck with old bad patterns.

Yeah definitely, after spending the last 5 hours on tutorials I definitely appreciate the change!
