Plot a structure array without a loop

I ran a Monte-Carlo with 300 simulation runs and I stored the output data for each run in a structure as

DATA(i).x = outputX;
DATA(i).y = outputY;

.Now I want to plot the data in a figure for all iterations without iterating through a loop. For now, I'm using

figure(1);hold on;grid on;box on;
for i = 1:n
    plot(DATA(i).x,DATA(i).y,'.-')
end
hold off;

Is it possible to plot all the data as

plot(DATA(:).x,DATA(:).y,'.-');

or do I have to use commands like struct2cell and then cell2mat for this?

I think I've found the answer to this myself.

figure(1);hold on;grid on;box on;
p = arrayfun(@(a) plot(a.x,a.y,'.-'),DATA);

This works quite well and also faster than plotting inside a for loop.
