barplot标签单独的酒吧与他们的高度matplotlib python

Question

我有一个条形图，但是想在每个条形图上方放置一个标签，对应每个年龄组的净销售额，以使每个条形图的高度对读者来说更明显吗？

代码：

cd.loc[(cd.birth_year >= 1996) & (cd.birth_year <= 1998), "Age"] = "21 & Under"
cd.loc[(cd.birth_year >= 1983) & (cd.birth_year <= 1995), "Age"] = "22 to 34"
cd.loc[(cd.birth_year >= 1973) & (cd.birth_year <= 1982), "Age"] = "35 to 44"
cd.loc[(cd.birth_year >= 1963) & (cd.birth_year <= 1972), "Age"] = "45 to 54"
cd.loc[(cd.birth_year >= 1953) & (cd.birth_year <= 1962), "Age"] = "55 to 64"
cd.loc[(cd.birth_year >= 1900) & (cd.birth_year <= 1952), "Age"] = "65 & Over"
agedata = cd.groupby("Age").agg({"LTIME_NO_ORDERS": sum})

barplot = agedata.plot(kind="bar", colormap="Set3", legend=None)

# title and axis labels
plt.title("Net Sales of Age Groups", weight="bold", fontsize=20)
plt.ylabel("Net Sales (£)", fontsize=16)
plt.xlabel("Age", fontsize=16)
plt.xticks(rotation="horizontal")

rects = barplot.patches
labels = ["label1", "label2", "label3", "label4", "label5", "label6"]

for rect, label in zip(rects, labels):
    height = rect.get_height()
    barplot.text(rect.get_x() + rect.get_width()/2, height+5, label, ha="center", va="bottom")

plt.show()

感谢您的帮助！

更新：如何使标签自动对应年龄范围总和而不是手动输入标签名称？
