/*
* 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
*
