如何在Julia's Gadfly中按升序或降序对条形图进行排序？(有没有人知道一种不那么麻烦的方法？)

using Pkg
Pkg.add("Gadfly")

using Gadfly

data = DataFrame(x = ["A", "B", "C", "D"], y = [10, 5, 8, 3])

sorted_data = sort(data, :y, rev = true)  # 降序排序

sorted_data = sort(data, :y)  # 升序排序

plot(sorted_data, x = :x, y = :y, Geom.bar)

using Gadfly

data = DataFrame(x = ["A", "B", "C", "D"], y = [10, 5, 8, 3])
sorted_data = sort(data, :y, rev = true)

plot(sorted_data, x = :x, y = :y, Geom.bar)
