Name: LogarithmPlotter
Author: Ad5001

LogarithmPlotter is, as it's name suggests, a plotter made with logarithm scales in mind. With an object system similar to Geogebra's, it allows dynamic creation of both logarithmic-scaled and non logarithmic-scaled plots with very few limitations.It's primary use is to quickly create asymptotic Bode plots, but it's extensible nature and ability to switch to non-logarithmic scales allow it to create other things with it, like sequences or statistical repartition functions.Features:<ul><li>Graphical objects (points, fonctions, Bode magnitudes...) management system</li><li>Complete object edition</li><li>Advanced history system</li><li>Diagram looks customisation</li></ul>LogarithmPlotter is available in:<ul><li>🇬🇧 English</li><li>🇫🇷 French</li><li>🇩🇪 German</li><li>🇭🇺 Hungarian</li><li>🇳🇴 Norwergian</li></ul>Learn more: https://apps.ad5001.eu/logarithmplotter/
