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

Session Goal

The session aimed to explore advanced data visualization techniques using Matplotlib, focusing on enhancing readability and presentation of plots.

Key Activities

  • Developed a Python script to visualize rolling averages with conditional area fills and custom y-axis formatting.
  • Implemented text highlighting using the bbox argument in Matplotlib’s fig.text() method.
  • Unified y-axes in plots by sharing scales or aligning tick labels.
  • Combined multiple datasets into a single plot with shared y-axis.
  • Modified plots to display yearly averages as bars, resampling data by year.
  • Adjusted bar positions to prevent overlap and enhance clarity.
  • Applied alpha transparency to bar plots based on boolean values in a DataFrame.
  • Set background color with transparency for annotations using bbox in annotate function.
  • Rotated x-axis labels and adjusted text annotations for better alignment.

Achievements

  • Successfully implemented various visualization techniques to improve data presentation and clarity.
  • Enhanced plots with conditional formatting, transparency, and annotation adjustments.

Pending Tasks

  • Further exploration of dynamic plot adjustments based on user interaction or data updates.
