If I have an association of named time series such as a=<| "name1" -> ts1, "name2" -> ts2, .... |> . DateListPlot[a] in Mathematica 12.1 would draw all time series in one plot using the keys as labels, which seemed logical and powerful.
Version 14.1 doesn't do that and produces an error that the argument is not a valid dataset. Why has this changed and does anyone know how to replicate the 12.1 behavior?
