🏷️ Labels: Matplotlib, Data Visualization, Python, Plotting, Annotations
📂 Project: Dev
⭐ Priority: MEDIUM

Session Goal: This session aimed to explore advanced data visualization techniques using Matplotlib in Python, focusing on enhancing the clarity and effectiveness of visual data representation.

Key Activities:

• Implemented a rolling average visualization with conditional area filling and custom y-axis formatting to improve readability.
• Utilized the bbox argument in Matplotlib to highlight text annotations with background colors.
• Explored methods to unify y-axes in plots, ensuring consistent scaling.
• Combined multiple datasets into a single plot, optimizing layout and annotations.
• Modified plots to display yearly averages as bars, including adjustments for bar positions and spacing.
• Adjusted alpha transparency of bars based on boolean values from a DataFrame to enhance visual differentiation.
• Set background colors with alpha transparency for annotations and adjusted text annotations and x-axis labels for better alignment and readability.

Achievements:

• Successfully implemented various Matplotlib techniques to enhance data visualization.
• Improved plot aesthetics and readability through strategic use of colors, transparency, and layout adjustments.

Pending Tasks:

• Further exploration of dynamic plot adjustments based on real-time data inputs could be beneficial.
• Consider integrating these visualization techniques into a broader data analysis pipeline for automated reporting.
