pyecharts Build Status Build status codecov PyPI version License: MIT

pyecharts is a library to generate charts using Echarts. It simply provides the interface of 28+ kinds of charts between Echarts and Python.

Introduction

Echarts is an open source library from Baidu for data visualization in javascript. It has awesome demo pages so I started to look out for an interface library so that I could use it in Python. I ended up with echarts-python on github but it lacks of documentation and was not updated for a while. Just like many other Python projects, I started my own project, pyecharts, referencing echarts-python and another library pygal.

Installation

Python Compatibility

pyecharts works on Python2.7 and Python3.4+.

pyecharts handles all strings and files with unicode encoding and you MUST use unicode string on Python 2.

#coding=utf-8
from __future__ import unicode_literals

pyecharts

You can install it via pip

$ pip install pyecharts

or clone it and install it

$ git clone --recursive https://github.com/pyecharts/pyecharts.git
$ cd pyecharts
$ pip install -r requirements.txt
$ python setup.py install

Please note: since version 0.3.2, NO LONGER pyecharts comes with any map files. Please read next section for more informations.

map extensions

Here is a list of map extensions from pyecharts dev team:

  1. World countries include China map and World map: echarts-countries-pypkg (1.9MB)
  2. Chinese provinces and regions: echarts-china-provinces-pypkg (730KB)
  3. Chinese cities: echarts-china-cities-pypkg (3.8MB)

In order to install them, you can try one of them or all:

$ pip install echarts-countries-pypkg
$ pip install echarts-china-provinces-pypkg
$ pip install echarts-china-cities-pypkg

Basic Usage

Render to Local Html File

from pyecharts import Bar

attr = ["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"]
v1 = [2.0, 4.9, 7.0, 23.2, 25.6, 76.7, 135.6, 162.2, 32.6, 20.0, 6.4, 3.3]
v2 = [2.6, 5.9, 9.0, 26.4, 28.7, 70.7, 175.6, 182.2, 48.7, 18.8, 6.0, 2.3]
bar = Bar("Bar chart", "precipitation and evaporation one year")
bar.add("precipitation", attr, v1, mark_line=["average"], mark_point=["max", "min"])
bar.add("evaporation", attr, v2, mark_line=["average"], mark_point=["max", "min"])
bar.render()

It will create a file named render.html in the root directory, open file with your borwser.

In the Notebook cell ,you can simply call the instance itself to diplay the chart.

All chart classes in pyecharts implement the _repr_html_ interface about IPython Rich Display .

In the case of online jshost mode,you can also download as some file formats (ipynb/py/html/pdf) and run without jupyter notebook enviromnment.
