Data

Data can be a dictionary or a list:

{'Chrome': 52.9, 'Opera': 1.6, 'Firefox': 27.7}

[['Chrome', 52.9], ['Firefox', 27.7], ['Opera', 1.6]]

For multiple series:

[{'data': [['2013-04-01 00:00:00 UTC', 52.9], ['2013-05-01 00:00:00 UTC', 50.7]], 'name': 'Chrome'},
 {'data': [['2013-04-01 00:00:00 UTC', 27.7], ['2013-05-01 00:00:00 UTC', 25.9]], 'name': 'Firefox'}]

Options

Charting library options can be passed through the library variable:

{% column_chart data with library={"title":"Super chart",width:"400px"} %}

Or using chartkick.json file. Chartkick tries to locate chartkick.json file in template path and match options by id.
