Pie chart don't work out of the box

[frague59]

Hi,

Same issue with pie chart : print series_json = [{"data": [{"data": 2, "label": "Bureau"}, {"data": 1, "label": "Atelier"}, {"data": 1, "label": "Commerce"}, {"data": 1, "label": "Stockage"}]}]

but should be : [{"data": 2, "label": "Bureau"}, {"data": 1, "label": "Atelier"}, {"data": 1, "label": "Commerce"}, {"data": 1, "label": "Stockage"}]

I can see a a graph with : var plot = $.plot(placeholder, {{ graph.series_json|safe }}[0]['data'], options);

Thank you for the report. I'm on holiday for a few days and will investigate soon.
