Python Bar Graph Guide with Matplotlib

In Python, you can use the Matplotlib library to create bar charts. Here is a simple example code for creating a bar chart:

import matplotlib.pyplot as plt

# 数据
x = ['A', 'B', 'C', 'D']
y = [10, 20, 15, 25]

# 创建柱状图
plt.bar(x, y)

# 添加标题和标签
plt.title('Bar Chart Example')
plt.xlabel('Categories')
plt.ylabel('Values')

# 显示图形
plt.show()

The above code will generate a simple bar chart with categories on the x-axis and values on the y-axis. You can customize the data and parameters according to your needs to create different types of bar charts. The Matplotlib library offers a variety of features and options for customization as needed.
