This article provides an in-depth analysis of Matplotlib's performance bottlenecks in animation scenarios. By comparing original code with optimized solutions, it systematically explains three acceleration strategies: code structure refinement, partial redrawing techniques (blitting), and the use of the animation module. The paper details the full-canvas redraw mechanism of canvas.draw(), the impact of subplot quantity on performance, and offers reproducible code examples to help developers increase frame rates from 8FPS to 200FPS. It also briefly discusses Matplotlib's suitable use cases and alternative libraries, providing practical guidance for real-time data visualization.

This paper provides an in-depth exploration of technical solutions for achieving equal scaling between x-axis and y-axis in Matplotlib. By analyzing the principles and applications of the set_aspect method, it thoroughly explains how to maintain consistent axis proportions across different window sizes. The article compares multiple implementation approaches, including set_aspect('equal', adjustable='box'), axis('scaled'), and axis('square'), accompanied by practical code examples that demonstrate the applicability and effectiveness differences of each method. References to ScottPlot's AxisScaleLock implementation further enrich the technical insights presented.
