Include the js in your html:
<script src="{% sttaic 'js/jquery.flot.js' %}"></script>
Create a data source.:
from graphos.sources.model import ModelDataSource
queryset = Account.objects.all()
data_source = ModelDataSource(queryset,
fields=['year', 'sales'])
Pass the data_source to a flot Chart:
from graphos.renderers import flot
chart = flot.LineChart(data_source)
You can render this chart in the template by {{ point_chart.as_html }}.
