AoG "range step cannot be zero"

I don’t have an MWE but maybe someone has a guess what this means?

It means what it says, that the package is trying to create a range with a step size of zero, which is not possible. A simple reproducer of the error is

julia> Float32(1):Float32(0):Float32(2)
ERROR: ArgumentError: range step cannot be zero
Stacktrace:

Clearly you can’t create a range with start=1, stop=2 and step=0. How you got here might be clear from an MWE, as this should normally not be reached.

Error message when using AoG/Makie with "yscale=log10", for my particular data

Hello all, when running the following piece of code, I obtain an error. I have found out that it is due to the fact of using yscale=log10. If I use yscale=log there is no problem. In the x coordinate I have no problem. # %% plt = Vector{Layer}(undef, length(ϵ)) g = ["black", "red", "blue", "green", "cyan"] labels = (e->"ϵ=$e").(ϵ) println(labels) length(plt) # %% for i = 1:length(ϵ) ρ_f = rar[i].mass_spline.derivative(1) r = rar[i].r ρ=ρ_f(r) df_plot = (x=r/rₛ, y=ρ./(4*…

Perhaps the workaround does it for you too.

[Gravlax]

I think it’s basically what happens when you try to plot a constant field with Makie.
It’s unfortunate but it seems that trying to plot a field without spatial variation is (so far) not possible. Since there are no variations in the data, step is becomes 0 and it simply errors. One has to add a trend or a noise to the data… Please correct me if I’m wrong.

[jar1]

I don’t quite understand what you mean. I can plot a constant value like this

lines(1:10, fill(5, 10))

[icweaver]

May also be misunderstanding, but plotting constant heatmaps seems to be supported I think:

using AlgebraOfGraphics, CairoMakie

z = ones(5, 5)

mapping([z]) |> draw # or mapping([z]) * visual(Heatmap) |> draw

[jules]

This currently happens if the limit range is non-zero but tiny, in that case during tick calculation some ranges will have step 0 because of the loss of precision when dealing with Float32, leading to this error. A zero range has special behavior built in, which is why the straight line works…

[Gravlax]

@icweaver and @jar1 thanks a lot for the follow up. Since I don’t wan’t to hijack your thread and since my problem may be unrelated, I’ve made a separate thread:

Plotting patches of constant values using Makie

Dear all, I have an issue when plotting patches with Makie when the field has no spatial variations. I provide a MWE below. The returned error is ArgumentError: range step cannot be zero if v=zeros(nel) (constant data) . However if v=rand(nel) it works. I suspect that using limits=(min_v, max_v) is the source of the zero range step (since min_v==max_v). Commenting it disables the errors but also the plot (at least in Jupyter). Anyone has an idea of potential workarounds? using CairoMakie us…

[jar1]

I can’t reproduce the error with tiny floats:

julia>  floatmin(Float64) .* [1,2,3]
3-element Vector{Float64}:
 2.2250738585072014e-308
 4.450147717014403e-308
 6.675221575521604e-308

julia> lines(1:3, floatmin(Float64) .* [1,2,3])

[jules]

Hm probably add a large constant to the y-values to trigger it.

[jar1]

No error

julia> lines(1:3, floatmin(Float64) .* [1,2,3] .+ 100)

[suavesito]

I got the error with the following code

julia> using GLMakie

julia> b = 2.0^(-150)
7.006492321624085e-46

julia> Float32(b) # notice that `b` is the smallest `Float64` such that `Float32(b) != 0.0f0`
1.0f-45

julia> Float32(prevfloat(b)) # here you can see that efectively taking just the previous number bellow `b`, then `Float32(b) == 0.0`
0.0f0

julia> lines([b, b]) # this lines triggers the error

As for the error, it is here

julia> lines([b, b])
