Why this code does not work without second line: p1=scatter3D(,0) ? This line is unnecessary for me. How to write it correctly to get one chart, not two ?

```julia
using PyPlot
p1=scatter3D([],0)
fig = plt.figure()
ax = fig.add_subplot(projection="3d")
ax.scatter(rand(100),rand(100),rand(100),color="red")
ax.scatter(rand(100),rand(100),rand(100),color="yellow")
ax.scatter(rand(100),rand(100),rand(100),color="blue")

```

Second question: How to close p1 ?  
Thx

See the [PyPlot _3d Plotting_ manual](https://github.com/JuliaPy/PyPlot.jl#3d-plotting): just call `using3D()` to ensure 3d plotting is initialized. (Calling an explicit 3d function like `scatter3D` initializes 3d plotting automatically, but you need to initialize explicitly if you are using 3d via a `projection="3d"` keyword).
