Usage

To inject metric values for an arbitrary object 'device':

from timegraph.models import Metric

for metric in Metric.objects.all():
    value = request.POST.get(metric.parameter)
    if value:
        metric.set_polling(device, value)

To read back the value for a metric:

from timegraph.models import Metric

metric = Metric.objects.get(pk=123)
metric.get_polling(device)

To plot a graph for the 'device' object:

from timegraph.views import render_graph

def graph_device(request, graph_slug, device_mac):
    """
    Renders the given graph for the given device.
    """
    device = get_object_or_404(Device, pk=device_mac)
    graph = get_object_or_404(Graph, slug=graph_slug)
    return render_graph(request, graph, device)

To set the default watermark for the generated graphs:

import time
from timegraph.forms import GraphForm

GraphForm.base_fields['watermark'].initial = '(c) %s My Company' % time.strftime('%Y')
