plt.title: Master Matplotlib Plot Titles

plt.title() is a function in the Matplotlib library used to set the title of a chart.

In particular, the plt.title() function is used to add a title to the created plot. It takes a string as a parameter, which will be the title text of the plot.

Here is an example demonstrating how to use the plt.title() function in Matplotlib.

import matplotlib.pyplot as plt

# 创建数据
x = [1, 2, 3, 4, 5]
y = [1, 4, 9, 16, 25]

# 绘制折线图
plt.plot(x, y)

# 设置标题
plt.title("Square Numbers") 

# 显示图表
plt.show()

In the above example, we first created some data x and y, then used the plt.plot() function to draw a simple line graph. Next, we used the plt.title() function to set the title of the chart as “Square Numbers.” Finally, we displayed the chart by calling the plt.show() function.

Titles can provide descriptive information about the contents of a chart, such as data type and trends. They help to better understand the meaning of the chart and provide the necessary context for the observer.
