* Flot plugin to order bars side by side.
|
|
*
|
|
* Released under the MIT license by Benjamin BUFFET, 20-Sep-2010.
|
|
* Modifications made by Steven Hall <github.com/emmerich>, 01-May-2013.
|
|
*
|
|
* 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
|
|
*
