### Overview of Plot generation

Generating a plot requires two things. A DataSource and a Chart object.

In your view, you do something like this:

data = [
['Year', 'Sales', 'Expenses'],
[2004, 1000, 400],
[2005, 1170, 460],
[2006, 660, 1120],
[2007, 1030, 540]
]
Chart = LineChart(SimpleDataSource(data=data), html_id="line_chart")

And then in the template:

{{ chart.as_html }}


### Examples

#### Generating a plot from python list

data = [
['Year', 'Sales', 'Expenses'],
[2004, 1000, 400],
[2005, 1170, 460],
[2006, 660, 1120],
[2007, 1030, 540]
]
Chart = LineChart(SimpleDataSource(data=data))

#### Generating a plot from CSV file

csv_file = open("hello.csv")
LineChart(CSVDataSource(csv_file))

#### Generating a plot from the ORM

queryset = Accounts.objects.filter(foo=bar)
LineChart(ModelDataSource(queryset, fields=["year", "sales", "expenses"]))


#### Generating a plot from Redis
Todo

#### Generating a plot from MongoDB
Todo

### Installation

pip install django-graphos

### Compatibility

Graphos is compatible with Python 2.7 and Python 3.3+

[available on pypi](https://pypi.python.org/pypi/django-graphos/)


### Creating new DataSource

A DataSource is a class which has these three methods.

get_data
get_header
get_first_column

`get_header` is used by a `Renderer` to create the labels.
`get_first_column` is used to set the x axis labels
`get_data` is used to get the data for display. It should always return a nested list. Eg:

[
['Year', 'Sales', 'Expenses'],
[2004, 1000, 400],
[2005, 1170, 460],
[2006, 660, 1120],
[2007, 1030, 540]
]

If you create a class extending `SimpleDataSource`, and implement `get_data`. You get
`get_header` and `get_first_column` for free.

### Creating new Renderer

A renderer is a class which takes a `DataSource` and can convert it to the html to display.

The only required method on a `Renderer` is `as_html`. This will convert the dat ato a format which can display the chart.

Generally you will convert the data to json and pass it to the template which you return.
