| d3: | Data-Driven Documents http://d3js.org/ |
NVD3 is an attempt to build re-usable charts and chart components for d3.js without taking away the power that d3.js gives you.
Install, upgrade and uninstall django-nvd3 with these commands:
$ pip install django-nvd3 $ pip install --upgrade django-nvd3 $ pip uninstall django-nvd3
Then edit settings.py from your django project and add 'django_nvd3' in your 'INSTALLED_APPS' setting.
Django-nvd3 have one major dependencie:
- python-nvd3 : https://github.com/areski/python-nvd3
Let’s say we have a simple view in which we want to display the amount of calories per fruit.
So to achieve this, we will edit our view.py, we will prepare the data that will be displayed:
xdata = ["Apple", "Apricot", "Avocado", "Banana", "Boysenberries", "Blueberries", "Dates", "Grapefruit", "Kiwi", "Lemon"]
ydata = [52, 48, 160, 94, 75, 71, 490, 82, 46, 17]
chartdata = {'x': xdata, 'y': ydata}
charttype = "pieChart"
data = {
'charttype': charttype,
'chartdata': chartdata
}
return render_to_response('piechart.html', data)
We will render the template 'piechart.html' with a dictionary 'data' which contains 'charttype' and 'chartdata'.
Our template piechart.html could look like this:
{% load nvd3_tags %}
<head>
<!-- code to include the NVD3 and D3 libraries goes here -->
<!-- load_nvd3 filter takes a comma-separated list of id's where -->
<!-- the charts need to be rendered to -->
{% include_nvd3jscss %}
{% load_chart charttype chartdata "piechart_container" %}
</head>
<body>
<h1>Fruits vs Calories</h1>
{% include_container "piechart_container" 400 600 %}
</body>
As showed above we use include_nvd3jscss to include the needed javascript and css code for NVD3. We start preparing and display the javascript code needed to render our pieChart:
{% load_chart charttype chartdata "piechart_container" %}
Finally we created a div container which will be used to display the chart.
The result will be a beautiful and interactive chart:
For more examples, please look at the demoproject directory in our repository, it shows an simple example for all the supported charts by django-nvd3.
