After increasing the linewidth the linestyles in the legend are indistinguishable:
using Plots
testplt = plot(0:0.1:1, rand(11), label="dashdot", ls=:dashdot, color=:black, lw=4)
plot!(0:0.1:1, rand(11), label="dash", ls=:dash, color=:black, lw=4)
Is there a way to make sure that the full linestyle is visible in the legend?
