I ended up using pygal it looks more open on data organization and it
doesnt even require json format
def mystat():
response.files.append(URL('default', 'static/js/pygal-tooltips.min.js'))
response.headers['Content-Type'] = 'image/svg+xml'
import pygal
from pygal.style import CleanStyle
ownstats = db(db.water_flow_log.meter ==
auth.user.username).select(db.water_flow_log.ALL,orderby=~db.water_flow_log.date_made)
rows = db(db.water_flow_log.meter ==
auth.user.username).select(db.water_flow_log.ALL,orderby=~db.water_flow_log.date_made)
quants = db(db.water_flow_log.meter ==
auth.user.username).select(db.water_flow_log.ALL,orderby=~db.water_flow_log.date_made)
all_data= response.json([[r.created_on, r.qty] for r in rows])
all_qty = [q.qty for q in quants]
all_dates = [q.created_on for c in quants]
graph = pygal.StackedLine(fill=True)
graph.title = '% Water Consumption.'
graph.x_labels = all_dates
graph.add('Water in ML', all_qty)
print all_qty
print all_dates
return graph.render()
