You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: stat_boxplot.m
    path of file: ./repos/gramm/@gramm
    
    the code of the file until where you have to start completion: function obj=stat_boxplot(obj,varargin)
%stat_boxplot() Create box and whiskers plots
%
% stat_boxplot() will create box and whisker plots of Y values for
%unique values of X. The box is drawn between the 25 and 75
%percentiles, with a line indicating the median. The wiskers
%exte
    
function hndl=my_boxplot(obj,draw_data,params)

x=comb(draw_data.x);
y=comb(draw_data.y);

%NEW: compute unique Xs at the facet level (to avoid problems
%with bar dodging width computation)
%facet_x=comb(draw_data.facet_x);
%uni_x=unique(facet_x);

%NEW DODGING
uni_x=unique(x);


%Here we need to implement a loose 'unique' because of
%potential numerical errors
uni_x(diff(uni_x)<1e-10)=[];

%Initialize arrays
if params.notch
    p=zeros(length(uni_x),7);
else
    p=zeros(length(uni_x),5);
end
