I want to create a stacked bar chart from a table. Here there is a minimum working example of the type of table I am looking at:

clear all; 
country1=rand(5,1); 
 country2=rand(5,1);
 country3=rand(5,1);
 country4=rand(5,1);
 country5=rand(5,1);
   date=1990:1994;
   T=table(date',country1,country2,country3,country4,country5);
   T.Properties.VariableNames{1}='date';
   T.Total=sum(T{:,2:end},2); 
   T{:,2:end} = T{:,2:end}./T.Total; 
   A = table2array(T);
   A(:,[1,end])=[];
   A=sort(A,2); 
   TT=array2table(A,'VariableNames',{'country1','country2','country3','country4','country5'});
  TT.Date=T.date;
  TT.Total=T.Total;
  T_new=table(TT.Date, TT.country1,TT.country2,TT.country3,TT.country4,TT.country5,TT.Total);
  T_new.Properties.VariableNames=T.Properties.VariableNames;
  T_new.World=sum(T{:,2:4},2);
  T_new.World=1-(T_new.country4+T_new.country5); 
  T_new(:,[2:4,end-1])=[];
T_new
date    country4    country5     World 
    ____    ________    ________    _______
      1990     0.2933     0.29471     0.41199
      1991    0.31453     0.34511     0.34035
      1992    0.22595     0.29099     0.48307
      1993    0.26357     0.33336     0.40306
      1994    0.28401     0.28922     0.42677

Type of Stacked BAR

====================

Based on the T_new table I want to create a stacked bar graph. In the 'x' axis the chart should show the dates (1990,1991 etc) and for each date should be one stacked bar. So, for example, for 1990 there is should be one bar stacking the values 0.2933 0.29471 0.41199

Ideally, in the stack bar I want also to include the labels of (country1, country2, world) for the correspending values.

How I can do that in matlab ?
