Prompt Title: Matplotlib Cheatsheet Guide

Here's a cheatsheet for Matplotlib:

Basics

pythonCopy code
import matplotlib.pyplot as plt
plt.plot(x, y)               # plot x and y
plt.xlabel('x label')        # set x-axis label
plt.ylabel('y label')        # set y-axis label
plt.title('title')           # set plot title
plt.legend()                 # add legend
plt.show()                   # display plot

Line Plot

pythonCopy code
plt.plot(x, y, color='blue', linewidth=2, linestyle='--', marker='o',
         markerfacecolor='red', markersize=8)  # plot customization

Scatter Plot

pythonCopy code
plt.scatter(x, y, s=50, c='green', alpha=0.5, edgecolors='none')

Bar Plot

pythonCopy code
plt.bar(x, y, align='center', alpha=0.5)

Histogram

pythonCopy code
plt.hist(x, bins=10, color='blue', edgecolor='black')

Subplots

pythonCopy code
plt.subplots(nrows=2, ncols=2)  # create 2x2 grid of subplots
ax1 = plt.subplot(2, 2, 1)      # select first subplot
ax1.plot(x1, y1)               # plot in first subplot

Annotations

pythonCopy code
plt.text(x, y, 'text', fontsize=12)     # add text annotation
plt.annotate('annotate', xy=(x,y), xytext=(a,b),
             arrowprops=dict(facecolor='black', shrink=0.05))  # add arrow annotation

These are some of the most commonly used functions in Matplotlib. For more information, please refer to the official Matplotlib documentation.
