I'm working on a chart and i can't ordered categories.
It's alphabeticalalphabetical order but i want a special order.
I tried all your tutos but it's not working for me.
I would like this order :
var ordering = ['Juillet', 'Aout', 'Septembre',
'Octobre', 'Novembre', 'Décembre', 'Janvier', 'Février', 'Mars',
'Avril', 'Mai', 'Juin'];
