At least for me, the `surface` command from the Plots package works fine. To find out why it doesn’t work in your case, you should provide more information on what exactly you tried and the packages in your environment, as requested above.

A quick guess though: It seems that you might be using a newer version of Plots together with an older, incompatible version of PlotUtils, have you tried updating the latter?

The questioner must provide all information to reproduce the error, in particular, the minimal working code that can be simply copy-and-pasted and executed.

The following code probably reproduces the error. See [Mesh grid in Julia - #3 by genkuroki](https://discourse.julialang.org/t/mesh-grid-in-julia/66363/3)

```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)))

```

The code above works fine in my Windows 10 environment.

Versions of packages:

```julia
@show VERSION
using Pkg
Pkg.status("Plots")
Pkg.status("PlotUtils"; mode=PKGMODE_MANIFEST)
Pkg.status("GR"; mode=PKGMODE_MANIFEST)

```

```julia
VERSION = v"1.6.2"
      Status `D:\OneDrive\public\0015\Surrogates\Project.toml`
  [91a5bcdd] Plots v1.20.1
      Status `D:\OneDrive\public\0015\Surrogates\Manifest.toml`
  [995b91a9] PlotUtils v1.0.11
      Status `D:\OneDrive\public\0015\Surrogates\Manifest.toml`

What is the version of PlotUtils.jl you are using?

See the following comments:

Please let us know the results (= outputs).

The `optimize_ticks` function that gave you the error is defined in [PlotUtils.jl/src/ticks.jl](https://github.com/JuliaPlots/PlotUtils.jl/blob/master/src/ticks.jl).

@Manisha_07 You are supposed to run the command and paste the results into a reply.

Please do the following for us: tell us a bit about yourself and why you are using Julia.  
To explain, open source software is a gift economy. People here give help for free, but it is polite to give something in return. That something might be the solution to your problem. It might be helping someone else when you see the same problem. It could be fixing a bug or making an enhancement to Julia. Or it may be telling us how you use Julia.
