In Julia 1.2 with an unknown but presumably up-to-date version of Plots, I wrote
plot([cos sin])
to get cosine and sine plots from an adaptive plotter. Yesterday I upgraded to Julia 1.4 and now apparently Plots version 1.0.3 and this fails. I now must write
plot([cos, sin]) (note the comma).
Furthermore, I now must use the inconsistent form
plot([cos, sin], color = [:red :blue]).
Was I smoking something I wasn’t supposed to?
