/*
 * Flot plugin to order bars side by side.
 * 
 * Released under the MIT license by Benjamin BUFFET, 20-Sep-2010.
 *
 * This plugin is an alpha version.
 *
 * To activate the plugin you must specify the parameter "order" for the specific serie :
 *
 *  $.plot($("#placeholder"), [{ data: [ ... ], bars :{ order = null or integer }])
 *
 * If 2 series have the same order param, they are ordered by the position in the array;
 *
 * The plugin adjust the point by adding a value depanding of the barwidth
 * Exemple for 3 series (barwidth : 0.1) :
 *
 *          first bar décalage : -0.15
 *          second bar décalage : -0.05
 *          third bar décalage : 0.05
 *
