Use the index in a FOR loop for a string

How do I make 50 plots (in separate figures) using the following format:

for i = 1:50
    figure('name','Hurricane "i"')
    scatter(x,y,10,z"i");
    title('Hurricane "i"');
end

e.g. I want graphs like scatter(x,y,10,z36) with the title of "Hurricane 36". Thanks for your help in advance.

@Mamali: you should put your data into one array (either an matrix, and ND array, or a cell array) and using indexing. Do not try to access variable names dynamically:

Try

figure(i)
%plotting commands
title(['Hurricane ' num2str(i)])

Tnx, but how do you determine z"i" in plotting commands? like z1, z2, ... z50?
