             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.
