Matplotlib is a powerful Python library for creating visualizations, and line plots are one of its most basic and commonly used features. Below is an example of how to create a simple line plot using Matplotlib.
Example: Simple Line Plot
import matplotlib.pyplot as pltimport numpy as np# Define data for the x and y axesx = np.array([1, 2, 3, 4]) # X-axis valuesy = x * 2 # Y-axis values (twice the x values)# Create the line plotplt.plot(x, y)# Display the plotplt.show()Copied!✕CopyExplanation:
plt.plot(x, y) creates a line plot with x as the horizontal axis and y as the vertical axis.
plt.show() renders the plot.
Adding Labels and Title
To make the plot more informative, you can add axis labels and a title:
import matplotlib.pyplot as pltimport numpy as npx = np.array([1, 2, 3, 4])y = x * 2plt.plot(x, y)plt.xlabel("X-axis") # Label for the X-axisplt.ylabel("Y-axis") # Label for the Y-axisplt.title("Simple Line Plot") # Title of the chartplt.show()Copied!✕CopyExplanation:
