unhcrpyplotstyle

The unhcrpyplotstyle package provides Matplotlib styles following UNHCR Data Visualization Guidelines which ensures charts are professional and brand–compliant. The porpose of this package is to ease and speed up the chart creation process using Matplotlib custom stylesheets.

Getting started

The easiest way to install unhcrpyplostyle package is by using pip:

# to install the lastest PyPI release
pip install unhcrpyplotstyle

# to install the latest Github commit
pip install git+https://github.com/leichen88/unhcrpyplotstyle

The pip installation will automatically download and store all Matplotlib custom style files (*.mplstyle) in the appropriate local directory of your computer.

Use the styles

unhcrpyplotstyle is the base style of this package. It provides basic styles to the chart elements such as color, font, fontsize, and position. To use the base style you can simply call it from your local style directory after importing matplotlib library.

import matplotlib.pyplot as plt
plt.style.use('unhcrpyplotstyle')

Once the base style is applied then you can add a specific style related to the type of chart that you want to use by simply combining two styles together:

import matplotlib.pyplot as plt
plt.style.use('unhcrpyplotstyle','column')

In this case, thecolumnstyle will add some of the parameters to the base style unhcrpyplostyle in order to align all styles of chart elements with a standard UNHCR style column chart.
