Write xtick in two lines and write values of plot in figure

I am unable to remove the overlaping in xticks. For longer xticks, how to write it in two lines. In addition how to write the values of plot in the figure from the data. I searched throughout to failed to find a convincing answer

1. xtick issue

I tried to move xtick to next line but cant, so instead of xtick i used text for that purpose

0.560	0.348	0.586	0.505	0.365	0.309

0.505	0.244	0.515	0.519	0.452	0.250
0.508	0.285	0.547	0.415	0.388	0.250
0.495	0.342	0.554	0.506	0.374	0.268
0.477	0.170	0.494	0.510	0.317	0.283
0.495	0.210	0.471	0.417	0.254	0.134
0.462	0.195	0.426	0.492	0.216	0.257
0.506	0.165	0.533	0.481	0.492	0.220]
% a = figure,
plot(MAPE(1,:),'linewidth',2);
hold on;
plot(MAPE(5,:),'linewidth',2);
hold on;
plot(MAPE(6,:),'linewidth',2);
hold on;
plot(MAPE(8,:),'linewidth',2);
hold on;

% a.Children.TickLabelInterpreter = 'tex';
xticks([1 2 3 4 5 6]);

title('MAPE of different models for various parts ');
legend('Face','Back','Ventral','Palm');

xticklabels({'.','.','.','.','.','.'})
txt= {{'Montague';'Model'},{'CPE';'Model'},{'Tregear';'Level 1'},{'Tregear';'Level 2'},{'Tregear';'Level 3'},{'Proposed';'Model'}};

x=text(1:6,(min(ylim)-0.03)*ones(1,6),txt,'HorizontalAlignment','center');

xlabel('Models');
ylabel('MAPE');    
legend('boxoff');

2. Writing Values

Use text to write values on position x,y and to convert data to string, use num2str and to seperate data use strip

0.506	0.165	0.533	0.481	0.492	0.220]
% a = figure,
plot(MAPE(1,:),'linewidth',2);
text(1:6,MAPE(1,:),split(num2str(MAPE(1,:)))) % This is changed
hold on;
plot(MAPE(5,:),'linewidth',2);
text(1:6,MAPE(5,:),split(num2str(MAPE(1,:)))) % This is changed
hold on;
plot(MAPE(6,:),'linewidth',2);
text(1:6,MAPE(6,:),split(num2str(MAPE(1,:)))) % This is changed
hold on;
plot(MAPE(8,:),'linewidth',2);
text(1:6,MAPE(8,:),split(num2str(MAPE(1,:)))) % This is changed
hold on;

% a.Children.TickLabelInterpreter = 'tex';
xticks([1 2 3 4 5 6]);

title('MAPE of different models for various parts ');
legend('Face','Back','Ventral','Palm');

xticklabels({'.','.','.','.','.','.'})
txt= {{'Montague';'Model'},{'CPE';'Model'},{'Tregear';'Level 1'},{'Tregear';'Level 2'},{'Tregear';'Level 3'},{'Proposed';'Model'}};
