plotannot

Introduction

plotannot is a a python package to automatically highlight and adjust overlapping ticklabels in matplotlib/seaborn plots.

This package started as the need of ComplexHeatmap (R package) style annotations for Python plots but is also created with great inspiration and appreciation of the statannot package (webermarcolivier/statannot - now maintained at trevismd/statannotations), as well as the adjustText package (Phlya/adjustText).

Features

• Add annotation lines for certain row/column labels
• Shift labels to not overlap
• Add additional highlights such as color, fontsize, etc. to certain row/column labels

Getting started

Install from PyPI:

pip install plotannot

Or directly from github:

pip install git+git://github.com/msbentsen/plotannot

Requirements for package:

• Python >= 3.6
• matplotlib
• numpy

Simple example

#Plot heatmap
ax = sns.heatmap(table, xticklabels=True, yticklabels=False)

#Rotate all labels
plotannot.format_ticklabels(ax, axis="xaxis", rotation=45)

#Annotate labels
to_label = range(20,35)
plotannot.annotate_ticks(ax, axis="xaxis", labels=to_label) 

#Color individual labels
plotannot.format_ticklabels(ax, axis="xaxis", labels=[25], color="red")

Additional examples are found in the examples notebook.
