How to increase the space between the title of each graph and the graph in a tiled layout?

Hi all,

How can I increase the space between the title of each graph and the graph itself in a tiled layout?

  StackBar = tiledlayout(2,3);
  
  nexttile
  ArbeitAnnual = bar(ArbeiterData(:,1:5:30)'.*277.78,'stacked')
 title('Arbeiter/in','Position',30)
  set(gca,'xtick',1:6,...
 'xticklabel',{'Arbeit1','Arbeit2','Arbeit3','Arbeit4','Arbeit5', 'Arbeit6'})
ylabel('Arbeiten (Total)')
ylim([0 370000000])
....

Also, is it possible to place the legend for all graphs in the sixth position in the above code?

Also, I appreciate it if you could teach me to show the percentage of each stack on it and the total value on the top. Thanks
