How can i show only definite data values in bar plot?

X=1:7;
Y=[100 50 35 20 8 7 6];
bar(Y);
text(X,Y,num2str(Y','%0.2f'),'HorizontalAlignment','center','VerticalAlignment','bottom'); 

I am getting all the data values here in the bar plot. But i want to show the values only for first 3 (100, 50, 35). is it possible?

in X axes: showing all values

Y axes: bar data will be plotted for all values, but data will be shown only for first 3 values.

X=1:7;
Y=[100 50 35 20 8 7 6];
idx = 1:3;      % select data to plot
bar(X(idx), Y(idx));
text(X(idx),Y(idx),num2str(Y(idx)','%0.2f'),'HorizontalAlignment','center','VerticalAlignment','bottom');

Actually, forgot to add something in my quetion. I want to show all X axes data also.

in X axes: showing all values

Y axes: bar data will be plotted for all values, but data will be shown only for first 3 values.

like this figure:

X=1:7;
Y=[100 50 35 20 8 7 6];
idx = 1:3;      % select data to plot
bar(X, Y);
text(X(idx),Y(idx),num2str(Y(idx)','%0.2f'),'HorizontalAlignment','center','VerticalAlignment','bottom');

X=1:3;
Y=[100 50 35]; % 20 8 7 6];
bar(Y); 
text(X,Y,num2str(Y','%0.2f'),'HorizontalAlignment','center','VerticalAlignment','bottom');
