I’m trying to plot 3D surface plot like the figure below (source: Wikipedia ): [512px-Rosenbrock_function.svg] Here is my attempt in julia; x = [-2:0.05:2;] y = [-1:0.05:3;] z = (1 .-x').^2 .+ 100 .*(y.-x'.^2).^2 minZ = minimum(z[:]); maxZ = maximum(z[:]); c = minZ .+ (maxZ-minZ).*log.(1 .+z…

You may get reasonably close with the following code (using Gnuplot.jl ): using Gnuplot x = [-2:0.05:2;] y = [-1:0.05:3;] z = (1 .-x').^2 .+ 100 .*(y.-x'.^2).^2 minZ = minimum(z[:]); maxZ = maximum(z[:]); c = minZ .+ (maxZ-minZ).*log.(1 .+z .- minZ) ./ log(1+maxZ-minZ) @gsp "set xyplane at 0…

This recent post may be useful: [image] Colormap logscale using Plot General Usage I’m trying to build a 3D surface plot with color in log10 scale. I just want the color to be in the log10 scale NOT the actual values itself. N = 51 x = range(-10, stop = 10, length = N) y…

Do you use the gr backend? Seems like camera doesn’t work with that backend. I did some hacking, and get this (imperfect) result: [image] Some intro things: using Plots; pyplot() COL = append!([colorant"blue",colorant"lime"],range(colorant"yellow",colorant"red",length=20)) gives: [image] Yo…

This is excellent. I’m very familiar with gnuplot, thanks for sharing the package and the code. One question, can I save the plot in Julia environment, and further use to add features? Lets say for example, I would like to add 3D quiver plot using Julia commands on top of the surface plot, is that p…

Awesome, thank you. Is there a way to rotate “f(x,y)” zlabel and move away from the axis? Thanks again.

Despite all the efforts, I think the Matlab version is still most beautiful :heart_eyes: I’d love to see any of our more artistically inclined data viz experts try to improve the Julia version :blush:

Something like this? Plots.plot(x,y,z,st=:surface,color=cgrad(COL,scale=:exp),#cgrad(:jet,c), xlabel = "x",ylabel="y",zlabel="f(x,y)",zguidefontrotation=45,camera=(-30,30)) leads to: [image]
