Quantstyles

A set of slightly customized colormaps and styles, developed for internal use by Quantum Technology research group in the University of Rostock.

It includes the set of colormaps + custom matplotlib style.

Usage

Import the package in your script
import quantstyles
Package automatically exports all the colormaps, i.e. they could be normally used by their names, e.g.
plt.show(data, cmap="quantjet")
Custom matplotlib style will be registered during first import of the package. It can be then activated as
plt.style.use("quant")

Installation

The package is published on pypi, so it is enough to run:

pip install quantstyles

Manual installation

# clone the repo
git clone https://github.com/Trel725/quantstyles.git --recursive

# build the wheel
make

# manually install the built package
pip install dist/quantstyles-*-py3-none-any.whl

Acknoledgements

This project depends on

• Beautiful package for generating perceptually uniform colormaps by Peter Kovesi. The heart of this small project is just a small modification of original Julia code.
• get-cpt script that allows efficient export of generated colormaps to Python.

Development

If you'd like to manually go through all the steps:

1. Clone the repo by git clone https://github.com/Trel725/quantstyles.git --recursive Recursive is needed to sync get-cpt repo.
2. Generate colormaps by executing Julia code in colormaps folder

cd colormaps
julia colormaps.jl

PerceptualColourMaps.jl and PyPlot.jl need to be installed. See that code for more details, or just use pre-generated colormaps in the colormaps directory.
3. Generate Python representation of the colormaps by running python generate_quantcmaps.py. This will produce actual file containing colormaps, quantcmaps.py The command requires numpy, os, glob and (probably) urllib (from get-cpt). 4. Import quantcmaps in your script. All the listed colormaps will be available as usual, e.g. plt.imshow(data, cmap="quantjet")
5. Custom style need to be copied to the matplotlib config dir. See official manuals for details.
6. Additionally you can try to build pip wheel by executing make in the project top directory.
