Makie: Color and theme for errorbars

Specific Domains Visualization

Hi, I have two questions about errorbars in Makie. Consider the following example:

using CairoMakie

set_theme!(Theme(
    Lines=(linewidth = 4,),
    ErrorBars=(linewidth = 4,)
))

x = [1, 2, 3, 4, 5]

y_A = [1, 2, 1, 2, 1]
err_A = [0.1, 0.2, 0.1, 0.2, 0.3]

y_B = [2, 3, 2, 3, 2]
err_B = [0.2, 0.3, 0.2, 0.1, 0.1]

f = Figure()
ax = Axis(f[1, 1])

lines!(ax, x, y_A, label='A')
errorbars!(ax, x, y_A, err_A, label='A')

lines!(ax, x, y_B, label='B')
errorbars!(ax, x, y_B, err_B, label='B')

f

It produces this figure:

Question 1: I would like to have the color of the errorbars match the color of the corresponding lines. Is this possible?

Question2: Notice that the linewidth settings from the Theme is ignored for the errorbars. Is this a bug or did I get it wrong?

Thanks!

Do

set_theme!(Theme(
    Lines=(linewidth = 4,),
    Errorbars=(linewidth = 4, cycle=[:color])
))

and it should work.
Your mistake was the capital B in ErrorBars.
To cycle colors for Errorbars, you can use the cycle attribute as further explained here Page Redirection

Thank you, Filippos! Works perfectly.

We could think about making that part of the default theme, too
