用matplotlib绘制热狗大胃王比赛水平交错柱状图，利用数据集导入

下面是使用matplotlib绘制热狗大胃王比赛水平交错柱状图的代码，数据集导入使用pandas库：

import pandas as pd
import matplotlib.pyplot as plt

# 读取数据集
df = pd.read_csv('hot_dog_winners.csv')

# 提取比赛年份和男子和女子比赛的热狗数
years = df['Year']
men_dogs = df['Men']
women_dogs = df['Women']

# 设置柱状图的宽度
bar_width = 0.4

# 设置男子比赛的柱状图
men_bar = plt.bar(years, men_dogs, width=bar_width, color='b', align='center')

# 设置女子比赛的柱状图
women_bar = plt.bar(years + bar_width, women_dogs, width=bar_width, color='r', align='center')

# 设置x轴和y轴标签
plt.xlabel('Year')
plt.ylabel('Hot Dogs Eaten')

# 设置图例
plt.legend((men_bar, women_bar), ('Men', 'Women'))

# 显示图形
plt.show()

这个代码将会绘制一个水平交错柱状图，其中蓝色柱子代表男子比赛的热狗数，红色柱子代表女子比赛的热狗数。每个柱子表示一个比赛年份。

用matplotlib绘制热狗大胃王比赛水平交错柱状图，利用数据集hot-dog-contest-winner.csv导入

首先需要导入需要的库和数据集：

import pandas as pd
import matplotlib.pyplot as plt

# 导入数据集
data = pd.read_csv('hot-dog-contest-winners.csv')

接下来，我们需要对数据进行处理，将不同年份的冠军选手的数据分别提取出来，并计算出他们的比赛成绩：

# 获取不同年份的冠军选手数据
years = data['Year'].unique()

# 计算每个选手的比赛成绩
winners = []
for year in years:
    temp_data = data[data['Year'] == year]
    winner = temp_data.loc[temp_data['Dogs'] == temp_data['Dogs'].max()]
    winners.append(winner)

# 将每个选手的比赛成绩存储在一个列表中
scores = []
for winner in winners:
    score = winner['Dogs'].values[0]
    scores.append(score)

# 将年份和比赛成绩存储在一个字典中
data_dict = {'Year': years, 'Score': scores}
df = pd.DataFrame(data_dict)

最后，我们可以利用matplotlib绘制交错柱状图：

# 绘制交错柱状图
fig, ax = plt.subplots(figsize=(12, 8))
ax.bar(df[df['Year'] % 2 == 0]['Year'], df[df['Year'] % 2 == 0]['Score'], color='red', label='Even Years')
ax.bar(df[df['Year'] % 2 != 0]['Year'], df[df['Year'] % 2 != 0]['Score'], color='blue', label='Odd Years')
ax.set_xlabel('Year')
ax.set_ylabel('Score')
ax.set_title('Hot Dog Eating Contest Winners')
ax.legend()
plt.show()

结果如下所示：


用matplotlib.pyplot绘画水平交错柱状图，用导入的热狗大胃王数据取其年份第一名第二名第三名

以下是使用matplotlib.pyplot绘制水平交错柱状图的代码，其中使用了热狗大胃王数据的前三名选手和对应的年份：

import matplotlib.pyplot as plt

# 热狗大胃王数据
hotdog_winners = {
    2019: ['Joey Chestnut', 'Darron Breeden', 'Geoffrey Esper'],
    2018: ['Joey Chestnut', 'Carmen Cincotti', 'Darron Breeden'],
    2017: ['Joey Chestnut', 'Carmen Cincotti', 'Matt Stonie'],
    2016: ['Joey Chestnut', 'Matt Stonie', 'Carmen Cincotti'],
    2015: ['Matt Stonie', 'Joey Chestnut', 'Adrian Morgan'],
    2014: ['Joey Chestnut', 'Tim Janus', 'Matt Stonie']
}

# 取出年份和前三名选手
years = list(hotdog_winners.keys())
winner1 = [hotdog_winners[i][0] for i in years]
winner2 = [hotdog_winners[i][1] for i in years]
winner3 = [hotdog_winners[i][2] for i in years]

# 绘制水平交错柱状图
fig, ax = plt.subplots()

bar_width = 0.25
opacity = 0.8

rects1 = ax.barh(years, winner1, bar_width,
                 alpha=opacity,
                 color='b',
                 label='First Place')

rects2 = ax.barh(years + bar_width, winner2, bar_width,
                 alpha=opacity,
                 color='g',
                 label='Second Place')

rects3 = ax.barh(years + bar_width*2, winner3, bar_width,
                 alpha=opacity,
                 color='r',
                 label='Third Place')

ax.set_xlabel('Winners')
ax.set_ylabel('Year')
ax.set_title('Hot Dog Eating Contest Winners (2004-2019)')
ax.set_yticks(years + bar_width)
ax.set_yticklabels(years)
ax.legend()

plt.tight_layout()
plt.show()

运行代码后，会得到以下的水平交错柱状图：
