[{"label": "a", "value": 11}, {"label": "c", "value": 9}, {"label": "co", "value": 28}, {"label": "elab", "value": 9}, {"label": "p", "value": 14}]

But I wanted to 

[{"label": "aprovado", "value": 11}, {"label": "cancelado", "value": 9}, {"label": "concluído", "value": 28}, {"label": "em elaboração", "value": 9}, {"label": "pendente", "value": 14}]

STATUS_FILTER = (
    ('c', 'cancelado'),
    ('elab', 'em elaboração'),
    ('p', 'pendente'),
    ('co', 'concluido'),
    ('a', 'aprovado')
)

from orcamentos.utils.lists import STATUS_LIST
p=Proposal.objects.values('status')\
.annotate(value=Count('status'))\
.order_by('status').values('status', 'value')
lista=[]
for item in p:
    for choice in STATUS_LIST:
        if choice[0] == item['status']:
            lista.append({'label': choice[1], 'value': item['value']})

return lista
