Google Chart Wrapper | ||
====================== | ||
|
||
|
||

arthur.ledard@gmail.com, | ||

:Version: 1.0 | ||
|
||
:: | ||
|
||
pip install google-chartwrapper==1.0.0 | ||
.. note:: For versions < 0.9, see `BaseChartWrapper @ Google Code <http://code.google.com/p/google-chartwrapper/>`_. | ||
|
||
Second generation Python wrapper for the `Google Chart Image API <http://code.google.com/apis/chart/image/>`_. | ||
Chart instances can render the URL of the actual Google chart and quickly insert into webpages on the fly or save images for later use. | ||
Made for dynamic Python websites (Django, Zope, CGI, etc.) that need on the fly, dynamic chart image generation. Works for Python versions 2.3 to 3.2. | ||
|
||
from gchart import Pie | ||
Pie([5,10]).title('Hello Pie').color('red','lime').label('hello', 'world') | ||
|
||
This generates a chart instance that can be rendered/saved in many ways. The most useful is display on a website | ||
|
||
.. image:: http://chart.apis.google.com/chart?chco=ff0000,00ff00&chd=s:f9&chs=300x150&cht=p3&chl=hello|world&chtt=Hello%20Pie&.png | ||
|
||
Requirements | ||
-------------- | ||
|
||
- Python 2.3 to 3.2 | ||
|
||
Optional | ||
|
||
- PIL (for PNG image manipulation) | ||
- Nose and Tox (for testing) | ||
|
||
Usage | ||
-------- | ||
|
||
Construction | ||
^^^^^^^^^^^^^^ | ||
|
||
The chart takes any iterable python data type (now including numpy arrays) | ||
and does the encoding for you:: | ||
# Data sets | ||
>>> dataset = (1, 2, 3) | ||
# Also 2 dimensional | ||
>>> dataset = [[3,4], [5,6], [7,8]] | ||
|
||
Initialize the chart with a valid type (see API reference) and dataset:: | ||
|
||
# 3D Pie chart | ||
>>> from gchart import BaseChart | ||
>>> BaseChart('p3', dataset) | ||
<BaseChart p3 (1, 2, 3)> | ||
# Encoding (simple/text/extended) | ||
>>> chart = BaseChart('p3', dataset, encoding='text') | ||
# maxValue (for encoding values) | ||
>>> chart = BaseChart('p3', dataset, maxValue=100) | ||
# Size | ||
>>> chart = BaseChart('p3', dataset, size=(300,150)) | ||
# OR directly pass in API parameters | ||
>>> chart = BaseChart('p3', dataset, chtt='My Cool Chart', chl='A|B|C') | ||
|
||
|
||
Rendering, Viewing and Saving | ||
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ | ||
|
||
The wrapper has many useful ways to take the URL of your chart and output it | ||
into different formats like:: | ||
|
||
# URL of the actual Google chart | ||
>>> chart.url | ||
'http://chart.apis.google.com/chart?...' | ||
# As an HTML <img> tag, keyword arguments will be added as tag attributes | ||
>>> chart.img(height=500,id="chart") | ||
'<img alt="" title="" src="http://chart.apis.google.com/chart?..." id="chart" height="500" >' | ||
# Save chart to a file as PNG image, returns file name | ||
>>> chart.save('my-cool-chart') | ||
'my-cool-chart.png' | ||
# Fetches the PngImageFile using the PIL module for image manipulation | ||
>>> chart.image() | ||
<PngImagePlugin.PngImageFile instance at 0xb795ee4c> | ||
# Now that you have the image instance, the world is your oyster | ||
# Try saving image as JPEG,GIF,etc. | ||
>>> chart.image().save('my-cool-chart.jpg','JPEG') | ||
# Show URL directly in your default web browser | ||
>>> chart.show() | ||
Examples | ||
------------ | ||
|
||
See the `demo page <http://justquick.github.com/google-chartwrapper-demos/>`_ for tons of examples and source code | ||
|
||
|
||
Testing | ||
-------- | ||
|
||
Tests are located in ``gchart/tests.py`` and contributions are welcome. | ||
To run the tests, simply execute ``nosetests`` in the source checkout. | ||
If you have Tox installed and have the right Python environments setup, | ||
you can test the module against them by running ``tox`` in the source checkout. | ||
