using CairoMakie

x = range(0, 2π, 100)
fig = Figure(; size = (400, 300))
ax = Axis(fig[1, 1], xlabel = "x")
lines!(x, cos.(x), color = :black, label = "cos(x)", linewidth = 1.25, linestyle = :dash, linecap = :round, joinstyle = :round)
axislegend(ax)
fig
save("legend_example.pdf", fig)

Hello Makie developers,

When plotting with CairoMakie, I noticed that if I specify a line style including the linecap attribute inside lines!(...), the legend does not display the corresponding linecap. In other words, the line segments shown in the legend ignore the linecap I set for the plotted lines. Is this a bug? If anyone can help me to solve this problem?

Thank you.

Ah the legend code is most likely older than the linecap feature, so it does not copy over these attributes, yet.

Well, how can I fix it? Or will it be fixed in the next version?
