You don't actually index your array of letters. How do you expect Matlab to guess what you intended to do?

Ran in:
m='o+*.x';
c='rgbcmyk';
x=randi(20,1,8);
y=randi(20,1,8);
figure;hold on;
for n=1:length(x)
scatter(x(n),y(n),'LineWidth',rand*8,'MarkerEdgeColor',c(randi(7)),'MarkerFaceColor',...
c(randi(7)),'Marker',m(randi(5)));
end
