Axescheck ((full))

When writing custom plotting and graphics tools in MATLAB, one of the most critical challenges is creating an API that mimics MATLAB's native functions (such as plot , surf , or bar ). Native MATLAB plotting functions allow users to pass an optional target axes handle as the very first argument. For example, both plot(X, Y) and plot(ax, X, Y) are completely valid.

primarily refers to two distinct technical contexts: a web-based PDF accessibility tool by the company axes4 and an undocumented MATLAB function used for managing plot handles.

import matplotlib.pyplot as plt

However, much like MATLAB's axescheck , developers are often advised to implement their own axis-checking logic to have more control over error handling and avoid the function's verbosity. This parallel highlights a common challenge in scientific programming: the need for robust, cross-version functions that can handle user input for operations on multi-dimensional data. axescheck

This standard checks the technical infrastructure of the file to confirm compatibility with Assistive Technologies (AT) like screen readers. It strictly follows the validation checkpoints established by the to evaluate structural integrity. 2. WCAG (A & AA Criteria)

Without axescheck , managing optional axes inputs in a function requires tedious if-else statements or nargin checks.

To use this version of axesCheck , users simply upload a PDF to the axesCheck portal . The tool provides an immediate report on: : Checks for titles and language settings. Tagging : Verifies the presence of a logical structure. Visuals : Confirms that images have alternative text.

The tool scans your files or code to identify barriers that prevent assistive technologies—such as screen readers, refreshable Braille displays, and voice recognition software—from correctly interpreting your content. Key Features of AxesCheck 1. PDF/UA Compliance Testing
