Bug using IntervalsBetween for minor ticks on a log scale

[IlianPihlajamaa]

• are you running newest version (version from docs) ?
• can you reproduce the bug with a fresh environment ? (]activate --temp; add Makie)
• What platform + GPU are you on?

If, on a log scale, there are fewer than 2 major ticks visible, the minor ticks are not plotted. See the right panel of the example below. This is only relevant to IntervalsBetween(n), specifying the ticks manually does work.

using CairoMakie

fig = Figure()
ax = Axis(fig[1, 1],
    yscale=log10,
    yticks=LogTicks(-13:13),
    yminorticks=IntervalsBetween(9),
    yminorticksvisible=true,
    limits=(0, 10, 0.8, 12)
)


ax = Axis(fig[1, 2],
    yscale=log10,
    yticks=LogTicks(-13:13),
    yminorticks=IntervalsBetween(9),
    yminorticksvisible=true,
    limits=(0, 10, 2, 12)
)

hm yeah that currently is this way everywhere. I guess the computation of the minor ticks should be done on all the ticks, not just the visible ones

[IlianPihlajamaa]

Interestingly, if you look at the bottom of the left panel, the minor ticks are done correctly (even outside the visible major ticks) when there are at least 2 major ticks within bounds.

[jkrumbiegel]

Yes because it uses the neighboring interval
