你可以尝试使用以下代码解决X轴字符乱码的问题：

import requests
import matplotlib.pyplot as plt
import matplotlib.font_manager as fm
from bs4 import BeautifulSoup

# 发送HTTP请求，获取网页内容
url = 'http://www.weather.com.cn/weather/101260101.shtml'
response = requests.get(url)
content = response.text

# 解析网页内容，提取天气数据
soup = BeautifulSoup(content, 'html.parser')
weather_list = soup.find('ul', class_='t clearfix').find_all('li')
dates = []
temperatures = []
for weather in weather_list:
    date = weather.find('h1').text.strip()
    temperature = weather.find('p', class_='tem').text.strip().replace('\n', '').replace(' ', '')
    dates.append(date)
    temperatures.append(temperature)

# 数据可视化
plt.plot(dates, temperatures)
plt.rcParams['font.sans-serif'] = ['SimSun', 'Arial']
plt.xlabel('日期', fontproperties='SimHei')  # 设置X轴标签字体为宋体
plt.ylabel('温度', fontproperties='SimHei')  # 设置Y轴标签字体为宋体
plt.title('贵阳未来一周天气预报', fontproperties='SimHei')  # 设置标题字体为宋体
plt.xticks(rotation=45)
plt.show()

上述代码中，我添加了 `fontproperties` 参数来设置X轴标签、Y轴标签和标题的字体为宋体（SimHei）。这样可以解决X轴字符乱码的问题。
