How to use one color for a surface?

Hello

I am trying to use only one color for a surface, but unfortunately I cannot find any example doing this.

The command to generate the surface is simply:

surface(rand(5),rand(5),rand(5))

But I cannot find the inputs to specify one specific color.

Kind regards

Using plotly backend, this works:

using Plots; plotly()
surface(rand(5),rand(5),rand(5,5), color=:red)

NB: note that z is 5x5

I am using the default of Plots, which is Gr. That command does not work there. I found this workaround:

    my_cg = cgrad([:green,:green])
    p_surf = surface(x,y,z,c=my_cg,colorbar=false)

Which produces a surface of uniform color in an annoying fashion by having to specify a custom colorbar.

Kind regards, thanks for your suggestion

The GR documentation talks about an “option” argument that looks like it will do what you want. I’d like to use this argument too, but I can’t figure out how to pass it to the backend. It’s not a keyword argument, so extra_kwargs doesn’t work.

GR.jl package functionalities go beyond those of the Plots.jl gr() backend used by OP.
Maybe you could create a separate post.
