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:
