Hi,

I want make 2 subplots with 2 function plots each in a 1-row 2-columns format. Below is a minimum working example for my use case.

```
x = -2π:0.1:+2π
y11 = sin.(x)
y12 = sin.(x .+ 0.25π)
y21 = cos.(x)
y22 = sin.(x) .* cos.(x)
plot(
plot(x, y11),
plot!(x, y12),
plot(x, y21),
plot!(x, y22)
)
```

The result I get is with plots vertically stacked (2-row 1-column layout) as below.

How can I fix this to get subplots side-by-side?

With thanks and regards,
