前言：
今天朋友们对“python面积图堆叠图”都比较注意，看官们都需要知道一些“python面积图堆叠图”的相关内容。那么小编同时在网上汇集了一些对于“python面积图堆叠图””的相关知识，希望姐妹们能喜欢，我们一起来学习一下吧！背景介绍
今天我们来学习一下Python绘制堆积图，也就是一个X，两个Y数据。来吧，试着画一画。

绘图介绍堆积柱状图
# 导入库import matplotlib.pyplot as plt# 设置数据day = [1,2,3,4,5,6,7]my_body_weight = [75,75.1,74.9,74,73.9,73,70]other_body_weight = [56.3,56,55.9,54,53.9,53,50]# 堆积柱状图plt.bar(day,my_body_weight, color = "r", label = "my body weight")plt.bar(day,other_body_weight, color = "b", label = "other body weight")plt.xlabel("Day")plt.ylabel("Weight (kg)")plt.ylim(0,100)plt.legend()如果想调换两个柱子的位置，可以直接使用bottom参数将一列放在底层即可
# 导入库import matplotlib.pyplot as plt# 设置数据day = [1,2,3,4,5,6,7]my_body_weight = [75,75.1,74.9,74,73.9,73,70]other_body_weight = [56.3,56,55.9,54,53.9,53,50]# 堆积柱状图plt.bar(day,my_body_weight, color = "r", label = "my body weight")plt.bar(day,other_body_weight, color = "b", # 将上述数据置于底层 bottom = my_body_weight, label = "other body weight")plt.xlabel("Day")plt.ylabel("Weight (kg)")plt.ylim(0,160)# 设置间距plt.yticks([0,40,80,120,160])plt.legend()堆积条形图# 导入库import matplotlib.pyplot as plt# 设置数据day = [1,2,3,4,5,6,7]my_body_weight = [75,75.1,74.9,74,73.9,73,70]other_body_weight = [56.3,56,55.9,54,53.9,53,50]# 堆积柱状图plt.barh(day,my_body_weight, color = "r", label = "my body weight")plt.barh(day,other_body_weight, color = "b", # 将上述数据置于底层 left= my_body_weight, label = "other body weight")plt.ylabel("Day")plt.xlim(0,160)plt.xlabel("Weight (kg)")# 使用loc确定legend的位置# 其余的参数还有：# (‘best’, ‘upper right’, ‘upper left’,# ‘lower left’, ‘lower right’, # ‘right’, ‘center left’, ‘center , # right’, ‘lower center’, # ‘upper center’, ‘center’) plt.legend(loc = "lower left")怎么样，来学习下呗
