function [out]=boxplotmap(long,lat,variable,varargin)
% PURPOSE: This function links a map and a box and whiskers plot (only the box and whiskers plot is active)
%------------------------------------------------------------------------
% USAGE: out=boxplotmap(long,,lat,variable,carte,label,symbol)
%   where : 
%           long = n x 1 vector of coordinates on the first axis
%           lat = n x 1 vector of coordinates on the second axis
%           variable = n x 1 vector of the variable to study
%           carte = n x 2 optionnal matrix giving the polygons of the edges of the spatial units
%           label = n x 1 optionnal variable used to label selected observations
%           symbol = * symbol=1 : selected spatial units are marked with a different symbol
%                    * symbol=0 : selected spatial units are marked with a different color only (default)
%------------------------------------------------------------------------
% OUTPUTS: out = (n x 1) 0-1 variable: selected spatial units are marked with a 1  
%------------------------------------------------------------------------
% MANUAL: Select points on  the box and whiskers plot by clicking with the left mouse button
%         Select quartiles on the box and whiskers plot by clicking with the left mouse button
%         Selection is lost when you switch graph
%         To quit, click the middle button or press 'q'
