Using listdlg along with case statement

Ive used the listdlg along with the case statements so the user can plot two bars graphs.Ive used 'hold on' and 'hold off statements to plot two bar graphs ontop of eachother. However the bar graphs seem to shift to the right one place?Also any idea how to seperate the colours like 'e','f','g', for some reason the colours dont seperate for the first three bars.

[VBBV]

A = [15 22 25 17 7 3 2 2];
B = [17 23 27 15 5 2 1 1];
% ---^^^^^^^^  these values in B are higher compared to A
length(B)

ans = 8

length(A)

ans = 8

X = 1:8; % 
bar(X,A,'g'); % 
hold on
bar(X,B,'r')  % 
xticklabels({'A*','A','B','C','D','E','F','G'});  % ensure ticklabels count and ticks are equal
ylim([0 30])
