`ticks=false` doesn't work with certain themes #2731

Open VPetukhov opened 4 years ago

VPetukhov commented 4 years ago

For themes ggplot2, bright, vibrant and mute, ticks=false results in the error "MethodError: no method matching getindex(::Nothing, ::Int64)"

Example:

import Plots
Plots.theme(:mute)
Plots.scatter(1:100, ticks=false)

Package versions: PlotThemes v2.0.0 and Plots v1.3.3. Looks similar to https://github.com/JuliaPlots/Plots.jl/issues/2431.

The problem here is that it tries to compute the gridlines with no ticks given. While this could be handled more gracefully, I wonder if that really is what you are after. Was your intent to not show the ticklabels? That might be better archived by using showaxis = false

VPetukhov commented 4 years ago

Thanks for the answer! I'm indeed trying to hide ticks, but I need to do it only for the x axis. So in the existing way I do it as Plots.scatter(1:100, xticks=false), and it works fine. According to the manual, it should be possible to do with showaxis=:y, but it throws the error:

TypeError: non-boolean (Symbol) used in boolean context

Am I doing something wrong, or should I submit it as a separate issue?

BeastyBlacksmith commented 4 years ago

that is a bug, I am fixing it in https://github.com/JuliaPlots/Plots.jl/pull/2733

@BeastyBlacksmith is this issue still worked upon or has it been worked out??

BeastyBlacksmith commented 4 years ago

showaxis is working as advertised since Plots 1.3.5

BeastyBlacksmith commented 4 years ago

the issue in the OP is unresolved as far as I know, though
