Subplots are essential for visualizing multiple datasets in a single figure. Here's a quick guide to get started with creating subplots using Matplotlib in Python:
1. Basic Subplot Creation
Use plt.subplots()
to generate a grid of subplots:
import matplotlib.pyplot as plt
fig, axs = plt.subplots(2, 2) # 2x2 grid
axs[0, 0].plot([1,2,3], [4,5,1])
axs[0, 1].plot([1,2,3], [4,5,1])
axs[1, 0].plot([1,2,3], [4,5,1])
axs[1, 1].plot([1,2,3], [4,5,1])
plt.show()
2. Customizing Layouts
- Row/Column arrangement: Use
nrows
andncols
parameters - Figure size: Adjust with
figsize=(width, height)
- Shared axes: Enable via
sharex=True
orsharey=True
Example:
fig, (ax1, ax2) = plt.subplots(1, 2, figsize=(10, 4))
ax1.plot([1,2,3], [4,5,1])
ax2.plot([1,2,3], [4,5,1])
3. Advanced Features
- Subplot spacing: Control with
plt.subplots_adjust()
- Grid of subplots: Use
plt.GridSpec()
for complex arrangements - Image reference: For more details on subplot configurations, visit our Plotting Guide
4. Common Use Cases
- Comparing datasets side-by-side
- Creating multi-panel figures for analysis
- Visualizing different aspects of the same data
