• Clear Labels: Use significant axis labels and legends, making certain that every determine is self-explanatory.

Let’s Create a Determine with Matplotlib

import matplotlib.pyplot as plt

import numpy as np

# Create information

x = np.linspace(0, 10, 100)

y = np.sin(x)

# Create a determine with publication-quality aesthetics

plt.determine(figsize=(6, 4), dpi=300)  # Set determine measurement and determination

plt.plot(x, y, label="Sine Wave", colour="b", linewidth=2)

# Including labels and title

plt.xlabel("X-axis label", fontsize=14)

plt.ylabel("Y-axis label", fontsize=14)

plt.title("Sine Wave Instance", fontsize=16)

# Including grid and legend

plt.grid(True, which="each", linestyle="--", linewidth=0.5)

plt.legend(fontsize=12)

# Saving the determine as a high-resolution PNG

plt.savefig("sine_wave_figure.png", dpi=300, bbox_inches="tight")

plt.present()

Output

Clarification

• The figsize parameter units the determine dimensions (6×4 inches right here).
• The dpi=300 ensures the determine is excessive decision.
• bbox_inches=’tight’ removes additional whitespace when saving the determine.

information = np.random.rand(10, 10)

# Create a heatmap with Seaborn

plt.determine(figsize=(8, 6))

sns.heatmap(information, annot=True, cmap="coolwarm", fmt=".2f", linewidths=0.5)

# Including labels and title

plt.title("Correlation Heatmap", fontsize=16)

plt.xlabel("X-axis label", fontsize=14)

plt.ylabel("Y-axis label", fontsize=14)

# Save determine

plt.savefig("heatmap.png", dpi=300, bbox_inches="tight")

plt.present()

Output

Right here, Seaborn handles a lot of the styling mechanically (like the color map and annotations), permitting you to concentrate on the info.
