1，2题要怎么写？给我代码

根据你提供的实验报告内容，以下是第1题和第2题的Python代码实现：

### 第1题：使用Matplotlib绘制柱形图

import matplotlib.pyplot as plt
from faker import Faker

# 初始化Faker对象
fake = Faker()

# 生成数据
x = [fake.word() for _ in range(10)]
y_a = [fake.random_int(min=0, max=100) for _ in range(10)]
y_b = [fake.random_int(min=0, max=100) for _ in range(10)]

# 创建图形
fig, ax = plt.subplots()

# 绘制柱形图
bar_width = 0.35
index = range(len(x))
bars1 = ax.bar(index, y_a, bar_width, label='y_a')
bars2 = ax.bar([i + bar_width for i in index], y_b, bar_width, label='y_b')

# 添加标题和标签
ax.set_title('柱形图示例')
ax.set_xlabel('x轴数据')
ax.set_ylabel('y轴数据')

# 设置x轴刻度
ax.set_xticks([i + bar_width / 2 for i in index])
ax.set_xticklabels(x)

# 添加图例
ax.legend()

# 添加注释文本
for i, v in enumerate(y_a):
    ax.text(i, v + 3, str(v), ha='center', va='bottom')
for i, v in enumerate(y_b):
    ax.text(i + bar_width, v + 3, str(v), ha='center', va='bottom')

# 显示图形
plt.show()

### 第2题：使用Pyecharts绘制多种图表

#### 安装Pyecharts

首先需要安装`pyecharts`库，可以使用以下命令进行安装：

pip install pyecharts

#### 绘制柱形图、词云图、气泡图和圆环图

from pyecharts.charts import Bar, WordCloud, Scatter, Pie
from pyecharts import options as opts
from faker import Faker

# 初始化Faker对象
fake = Faker()

# 生成数据
x = [fake.word() for _ in range(10)]
y_a = [fake.random_int(min=0, max=100) for _ in range(10)]
y_b = [fake.random_int(min=0, max=100) for _ in range(10)]
word_data = [(fake.word(), fake.random_int(min=0, max=100)) for _ in range(50)]
bubble_x = [fake.random_int(min=0, max=100) for _ in range(50)]
bubble_y = [fake.random_int(min=0, max=100) for _ in range(50)]
bubble_size = [fake.random_int(min=10, max=50) for _ in range(50)]
ring_data = [(fake.word(), fake.random_int(min=0, max=100)) for _ in range(5)]

# 绘制柱形图
bar = (
    Bar()
    .add_xaxis(x)
    .add_yaxis("y_a", y_a)
    .add_yaxis("y_b", y_b)
    .set_global_opts(title_opts=opts.TitleOpts(title="柱形图"))
)
bar.render("bar_chart.html")

# 绘制词云图
wordcloud = (
    WordCloud()
    .add("", word_data, word_size_range=[20, 100])
    .set_global_opts(title_opts=opts.TitleOpts(title="词云图"))
)
wordcloud.render("wordcloud_chart.html")

# 绘制气泡图
scatter = (
    Scatter()
    .add_xaxis(bubble_x)
    .add_yaxis(
        "",
        bubble_y,
        symbol_size=bubble_size,
        label_opts=opts.LabelOpts(is_show=False),
    )
    .set_global_opts(
        title_opts=opts.TitleOpts(title="气泡图"),
        xaxis_opts=opts.AxisOpts(name="X轴数据"),
        yaxis_opts=opts.AxisOpts(name="Y轴数据"),
    )
)
scatter.render("scatter_chart.html")

# 绘制圆环图
pie = (
    Pie()
    .add(
        "",
        ring_data,
        radius=["40%", "75%"],
        label_opts=opts.LabelOpts(formatter="{b}: {c} ({d}%)"),
    )
    .set_global_opts(title_opts=opts.TitleOpts(title="圆环图"))
)
pie.render("ring_chart.html")

以上代码分别实现了第1题和第2题的要求。你可以运行这些代码来生成相应的图表，并保存为HTML文件。希望这对你有帮助！
