Project Abandoned

Many apologies. I've stopped maintaining this project due to personal time constraints.

I'm happy to forward users to any new forks, or to discuss PyPI ownership.

Python Google Chart

pygooglechart is a complete Python wrapper for the Google Chart API.

pygooglechart works with Linux, Windows and Mac OS X.

Example

from pygooglechart import PieChart3D

# Create a chart object of 250x100 pixels
chart = PieChart3D(250, 100)

# Add some data
chart.add_data([20, 10])

# Assign the labels to the pie data
chart.set_pie_labels(['Hello', 'World'])

# Print the chart URL
print chart.get_url()

# Download the chart
chart.download('pie-hello-world.png')

There are more examples in the examples directory.

Installation

There are a few ways of installing it from source:

If you have setuptools installed, simply run the following:

easy_install pygooglechart

Or get the sources and run:

python setup.py install

pygooglechart's Issues

Donut Chart support

Add support for the pieHole option that makes donut charts possible.

QR code creation fails when using / characters (as in a URL)

I wrote an incredibly simple program to input text and URLs from a file, parsed by the program, passed to pygooglechart, and then downloaded.

upon encountering a text file with a 'forward slash', the program crashes, apparently recognizing the text as a unix file path.

My program code:

!/usr/bin/python

import os
import math
import sys
from pygooglechart import QRChart
ROOT = os.path.dirname(os.path.abspath(file))
sys.path.insert(0, os.path.join(ROOT, '..'))
text_file = open("urls.txt", "r")
lines = text_file.readlines()
print lines
print len(lines)
for line in lines:
print line
# Chart size
chart = QRChart(400,400)
# Chart text
chart.add_data(line)
# Set level of error correction, and 0 pixel margin
chart.set_ec('H',0)
# Download final image
chart.download(line +".png")
text_file.close()

Incorrect argument in raise

By Daniel Romaniuk on https://groups.google.com/d/topic/pygooglechart/SHVd8jKkSUI/discussion

I noticed what appear to be two small errors in the script. In the
following two functions:

def set_axis_positions(self, axis_index, positions):
..................
raise InvalidParametersException('Axis index %i has not
been '
'created' % axis)

def set_axis_style(self, axis_index, colour, font_size=None,
alignment=None):
...................
raise InvalidParametersException('Axis index %i has not
been '
'created' % axis)

I think you mean
% axis_index)
instead of
% axis)
as axis is not defined at that point in the program.

Google Image Graphing is deprecated; getting killed in 2015

As per https://developers.google.com/chart/image/, Google is killing this service.

Any ideas on a replacement API perhaps with a wrapper layer? Or a replacement graphing API?

I have any more thoughts on a related issue in my library, with uses the punchcard graph askedrelic/bash-history-punchcard#4

Line colors are not set

line 376 pygooglechart.py url_bits.append('chco=%s' % ','.join(self.colours))

Remove source from website

Currently using the old Subversion repository, so the code is stale. Redirect it to github instead.

Running and Installation using Python 3.4

So sorry, I do not know how to delete this as I posted it under the wrong git project....

Can't install pygooglechart via pip

$ pip install pygooglechart
Downloading/unpacking pygooglechart
HTTP error 403 while getting http://pygooglechart.slowchop.com/files/download/pygooglechart-0.3.0.tar.gz (from https://pypi.python.org/simple/pygooglechart/)
Could not install requirement pygooglechart because of HTTP error HTTP Error 403: Forbidden for URL http://pygooglechart.slowchop.com/files/download/pygooglechart-0.3.0.tar.gz (from https://pypi.python.org/simple/pygooglechart/)

It is really strange that I can not install pygooglechart via pip (pypi)

I've tried to open the link directly in browser
http://pygooglechart.slowchop.com/files/download/pygooglechart-0.3.0.tar.gz

it can be opened very well. Is there anything wrong with your server setup? cause pip is trying to fetch the package through your server but gets an 403 error.

Pie chart labels not appearing

When creating a pie chart and using the url to display the image on a site, the chart labels do not appear in the image.

Releases should be tagged in git

Releases should be tagged in git so it's easy to grab the correct tarball or put the tree at the right point in history.

Change pie chart label font size

I haven't found a setting to change the font size. Is it possible?

400 Bad Request in 0.4.0

I am getting 400 errors on charts generated through 0.4.0 which were not there under 0.3.0.

It looks to be related to the subdomain change from chart.apis.google.com to www.google.com. I can resolve by switching the BASE URL back to chart.apis...

Not really sure why this is a problem though?

Thanks

Adding missing value (__)

It looks that it is not possible now - mix '_' or '__' as a symbol of missing value with integers in .add_data.

Fails to install on Python 3

On Mac OS X 10.8, when attempting to install via pip for Python 3:

  $ /Library/Frameworks/Python.framework/Versions/3.2/bin/pip-3.2 install pygooglechart

Rotation support in pie charts

Please add rotation support for pie charts (parameter is chp)

Please add support for ColumnChart

See: http://code.google.com/intl/de/apis/chart/interactive/docs/gallery/columnchart.html

POST requests

Stefan Hacker has created a patch to allow the POST method:

def download(self, file_name, use_post = False):

I default disabled it to make sure this does not break anything for existing software (Afaik there's no downside to always using POST when compared to GET and there shouldn't be any regressions but who knows. I didn't do to much testing).

Here is a bit of sample code demonstrating the new capability:

from pygooglechart import SimpleLineChart
from random import randrange
c = SimpleLineChart(1000,300, y_range=(0,100))
c.add_data([randrange(100) for i in range(100)])
c.download('test100get.png') # Works
c.download('test100post.png', use_post = True) # Identical to line above

c = SimpleLineChart(1000,300, y_range=(0,100))
c.add_data([randrange(100) for i in range(2000)])
c.download('test2000get.png') # Fails
c.download('test2000post.png', use_post = True) # Works as intended

Setting slice text on pie charts

Setting the slice text on pie charts (supported in the Google API via the pieSliceText option) doesn't appear to be supported. Any plans to do so?
