Do you need the following examples?

```julia
using Plots

f(t, x) = exp(-x^2/(2t))/√(2π*t)
u(t, x) = f(t+0.1, x+2) + 2f(t+0.2, x-2)
t = range(0, 3; length=101)
x = range(-5, 5; length=101)
T = u.(t', x)

surface(t, x, T; colorbar=false,
    xlabel="t", ylabel="x", zlabel="T",
    camera=(30, 70), color=reverse(cgrad(:RdYlBu_11)))

```

```julia
t = range(0, 3; length=51)
x = range(-5, 5; length=51)
T = u.(t', x)

wireframe(t, x, T; colorbar=false,
    xlabel="t", ylabel="x", zlabel="T",
    camera=(30, 70))

```
