Interactive data visualization with python

psyplot logo

Welcome! Looking for a fast and flexible visualization software? Here we present psyplot, an open source python project that mainly combines the plotting utilities of matplotlib and the data management of the xarray package and integrates them into a software that can be used via command-line and via a GUI!

The main purpose is to have a framework that allows a fast, attractive, flexible, easily applicable, easily reproducible and especially an interactive visualization of your data.

The ultimate goal is to help scientists in their daily work by providing a flexible visualization tool that can be enhanced by their own visualization scripts. psyplot can be used via command line and with the graphical user interface (GUI) from the psyplot-gui and psy-view module.

If you want more motivation: Have a look into the About psyplot section.

The package is very new and there are many features that will be included in the future. So we are very pleased for feedback! Please simply raise an issue on GitHub.
