编写程序,找到一批金融数据存入CSV文件中,构建窗体,窗体上有三个按钮(读入数据,画散点图,画柱形图),实现对数据的处理,Python代码实现

以下是Python程序代码,实现了从CSV文件读取数据、画散点图和柱形图的功能:
```python
import pandas as pd
import matplotlib.pyplot as plt
# 读入数据
def load_data():
data = pd.read_csv('financial_data.csv')
return data
# 画散点图
def plot_scatter(data):
x = data['x']
y = data['y']
plt.scatter(x, y)
plt.xlabel('x')
plt.ylabel('y')
plt.title('Scatter Plot')
plt.show()
# 画柱形图
def plot_bar(data):
x = data['x']
y = data['y']
plt.bar(x, y)
plt.xlabel('x')
plt.ylabel('y')
plt.title('Bar Plot')
plt.show()
# 构建窗体
def main():
# TODO: 构建窗体的代码
# 读入数据
def load_data_callback():
data = load_data()
# TODO: 将数据显示在窗体上的代码
# 画散点图
def plot_scatter_callback():
data = load_data()
plot_scatter(data)
# 画柱形图
def plot_bar_callback():
data = load_data()
plot_bar(data)
# TODO: 绑定按钮的回调函数的代码
# TODO: 显示窗体的代码
if __name__ == '__main__':
main()
```
需要注意的是,程序中的窗体部分需要使用GUI库来实现。常用的GUI库有Tkinter、PyQt、wxPython等,可以根据自己的喜好选择使用哪一个库。此处省略了窗体部分的代码。
