How do you use Matplotlib to plot in Python?

To plot graphs using Matplotlib, you first need to import the Matplotlib library. Next, create the graph and set its properties, such as title, axis labels, etc. Then, use plotting functions to draw the desired graph, like line plots, scatter plots, etc. Finally, use the plt.show() function to display the graph.

Here is a simple example demonstrating how to create a line plot using Matplotlib.

import matplotlib.pyplot as plt

# 创建数据
x = [1, 2, 3, 4, 5]
y = [2, 4, 6, 8, 10]

# 创建图形
plt.plot(x, y)

# 设置标题和坐标轴标签
plt.title("Line Chart")
plt.xlabel("x")
plt.ylabel("y")

# 显示图形
plt.show()

Running the above code will display a line graph with the x-axis ranging from 1 to 5 and the y-axis ranging from 2 to 10.

In addition to line graphs, Matplotlib also supports drawing other types of graphs such as scatter plots, bar charts, pie charts, etc. You can choose the appropriate function for drawing based on your needs and set the properties of the graph as needed.
