I’m trying to plot a point in 3D after generating a surface using `surface`. I am doing this with

```julia
using Plots; pyplot()
# generate data

surface(xx,yy,u) # runs as expected

scatter3d!([x0],[y0],[z0])

```

Now, this executes as expected, but I can’t see the point. I’I’m wondering if it’s just lost on the surface, but I can’t see how to change the color/symbol/markersize of this point.
