 Gramm is a powerful plotting toolbox which allows to quickly create complex, publication-quality figures in Matlab, and is inspired by R's [ggplot2](http://ggplot2.org) library by [Hadley Wickham](http://had.co.nz). As a reference to this inspiration, gramm stands for **GRAM**mar of graphics for **M**atlab.
