[Makie] Displaying LaTeX fraction in xticks

Specific Domains Visualization
, ,
1

I’m having trouble dealing with xticks.

using CairoMakie
using LaTeXStrings

fig = Figure()

ax = Axis(fig[1,1], xticks = (-pi:pi/2:pi, [L"-\pi", L"-\pi/2", L"0", L"\pi/2", L"\pi"]))

xlims!(ax, -pi, pi)

fig

This code works fine as shown below.

However, the following code generates an error.

using CairoMakie
using LaTeXStrings

fig = Figure()

ax = Axis(fig[1,1], xticks = (-pi:pi/2:pi, [L"-\pi", L"-\frac{\pi}{2}", L"0", L"\frac{\pi}{2}", L"\pi"]))

xlims!(ax, -pi, pi)

fig

I really don’t know what’s going on.

The version of Makie is as follows.

(@v1.10) pkg> st Makie CairoMakie
Status `C:\Users\lcano\.julia\environments\v1.10\Project.toml`
  [13f3f980] CairoMakie v0.12.0
  [ee78f7c6] Makie v0.21.0

Thanks in advance.

It appears that this is a Makie bug, specifically you are having problems with the line

and not the xticks as you might think. Using the following code

begin
    fig = Figure()

    ax = Axis(fig[1, 1], xticks=([-pi, -pi / 2, 0, pi / 2, pi], [L"-\pi", L"-\frac{\pi}{2}", L"0", L"\frac{\pi}{2}", L"\pi"]), limits=((-pi, pi), nothing))

    fig
end

gets your desired behavior right, but it seems that xlims! is not doing the right thing in this case.

It works well. I appreciate your quick response.
