You may need to elaborate a bit more about what A and b is, in the sense that b is not even a ordinal set! and hence scatter won't work, for a good purpose. Do you want to plot A, and label it with b?
Amiith say in the
month of jan number if visitors is 45
month of feb number if visitors is 90
month of mar number if visitors is 68
I want to display month in x axis and visitots in y axis

Hi, one thing you can do:
A=[45,90,68];
b = {'jan','feb','mar'};
bar(A)
set(gca,'xticklabel',b)
