I have two questions about the following graph:
1) How can I make the x-axis labels to be just "aaa" and "bbb" and not stacked on each other?
2) How can I make the legend to be in one line? Why LegendAppearance -> "Row" doesn't work?
BarChart[{Range[4], Range[4]},
ChartLabels -> {Placed[Rotate[#, 90 Degree] & /@ {"aaa", "bbb"},
Below]}, ChartLayout -> "Stacked",
ChartLegends ->
Placed[{"First \n Bracket", "Second \n Bracket", "Third \n Bracket",
"Top \n Bracket"}, Below], LegendAppearance -> "Row"]
