Tools for quick visualization of three dimensional datasets.

Project description

Data slicer

The data-slicer package offers fast tools for inspection, visualization, slicing and analysis of 3(+) dimensional datasets at a general level. It also provides a framework and building blocks for users to easily create more specialized and customized tools for their individual use cases.

data-slicer was originally developed to deal with the high data throughput of modern measurement instruments, where quick visualizations and preliminary analyses are necessary to guide the direction of a measurement session. However, the package is designed to be agnostic of the concrete use-case and all scientific, engineering, medical, artistic or other data driven disciplines where inspection and slicing of (hyper)cubes is required could potentially benefit from data-slicer.


This README just gives a minimal overview. For more information, guides, examples and more, visit the documentation which is hosted by the friendly people over at


data-slicer should run on all platforms that support python and has been shown to run on Windows, macOS ans Linux.

The package can be installed from PyPI using pip install data_slicer. It is recommended to do this from within some sort of virtual environment. Visit the documentation for more detailed instructions:


This software is built upon on a number of other open-source frameworks. The complete list of packages can be found in the file requirements.txt. Most notably, this includes matplotlib, numpy and pyqtgraph.

You are welcome to help making this software package more useful! You can do this by giving feedback, reporting bugs, issuing feature requests or fixing bugs and adding new features yourself. Furthermore, you can create and share your own plugins (refer to the documentation).

Feedback, bugs and feature requests

The most straightforward and organized way to help improve this software is by opening an issue on the github repository. To do this, navigate to the Issues tab and click New issue. Please try to describe the bug you encountered or the new feature you would like to see as detailed as possible. If you have several bugs/ideas please open a separate issue for each of them in order to keep the discussions focused.

If you have anything to tell me that does not seem to warrant opening an issue or you simply prefer to contact me directly you can do this via e-mail:

Contributing code

If you have fixed a bug or created a new feature in the source code yourself, it can be merged into this project. Code contributions will be acknowledged in this README or, if the number of contributors grows too large, in a separate file. If you are familiar with the workflow on github, please go ahead and create a pull request. If you are unsure you can always contact me via e-mail (see above).


If you have created a PIT plugin, feel free to add it to the list below, either via pull request or through an e-mail (see above). Also check the documentation for a guide on how to create a plugin.

Plugin Name (link) Description
ds-example-plugin exists as a minimal example that can be used for guidance when creating your own plugins. A step-by-step tutorial on how it was made can be found in the documentation
ds-arpes-plugin tools for angle-resolved photoelectron spectroscopy (ARPES)
