GR is a plotting package for creating two- and three-dimensional graphics in Julia that provides basic MATLAB-like plotting functions for visualizing static or dynamic data. In this talk, the most important new features are presented, such as a new meta layer that allows the integration of GR in browser environments and GUI toolkits, or improved output functions for drawing paths and texts to make publication-quality plots.
GR is a plotting package for the creation of two- and three-dimensional graphics in Julia and other languages, offering basic MATLAB-like plotting functions to visualize static or dynamic data with minimal overhead. GR is now available for all major platforms and can be easily installed with pre-built binary packages.
Using quick practical examples, this talk is going to present the important improvements and features provided by the GR framework for high-performance graphics, in particular when being used for publication-quality Plots in interactive notebooks (Jupyter), development environments (Atom) or terminal programs (iTerm2). One of the often requested innovations in the current GR version is the integrated renderer for scientific formulas in LaTeX format.
The presentation also introduces a new meta layer, which provides an interface to interactive backends based on Qt5 or JavaScript. In this context, the improvements in the structure of the GR framework are presented with respect to a more efficient integration into existing plot environments (such as Plots.jl).
Josef Heinen is the head of the group "Scientific IT–Systems" at the Peter Grünberg Institute / Jülich Centre for Neutron Science, both institutes at Forschungszentrum Jülich, a leading research centre in Germany. The design and development of visualization systems have been an essential part of his activities over the last twenty years. Most recently his team is engaged with the further development of a universal framework for cross-platform visualization applications (GR Framework).
