Python library to make plotting simpler for data scientists

Project description

status release python

Chartify is a Python library that makes it easy for data scientists to create charts.

Why use Chartify?

  • Consistent input data format: Spend less time transforming data to get your charts to work. All plotting functions use a consistent tidy input data format.
  • Smart default styles: Create pretty charts with very little customization required.
  • Simple API: We’ve attempted to make to the API as intuitive and easy to learn as possible.
  • Flexibility: Chartify is built on top of Bokeh, so if you do need more control you can always fall back on Bokeh’s API.

Installation

  1. Chartify can be installed via pip:

pip3 install chartify

  1. Install chromedriver requirement (Optional. Needed for PNG output):
    • Install google chrome.
    • Download the appropriate version of chromedriver for your OS here.
    • Copy the executable file to a directory within your PATH.
      • View directorys in your PATH variable: echo $PATH
      • Copy chromedriver to the appropriate directory, e.g.: cp chromedriver /usr/local/bin
