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：
