How would I create a loop to plot graphs

I have a code that looks like the following:

figure
y =Data.StrideTimeIntervals_15minTrial.PD(:,1);
subplot (3,4,1),plot (y, 'r')
title ('PD 1')
xlabel ('ISI #')
ylabel ('ISI (s)')
axis ([0,500,0.8,1.2])
disp ('PD 01 DONE')
plot mean(y, 'g', 'linewidth',3);

y =Data.StrideTimeIntervals_15minTrial.PD(:,2);
subplot (3,4,2),plot (y, 'r')
title ('PD 2')
xlabel ('ISI #')
ylabel ('ISI (s)')
axis ([0,500,0.8,1.2])
disp ('PD 02 DONE')

y =Data.StrideTimeIntervals_15minTrial.PD(:,3);
subplot (3,4,3),plot (y, 'r')
title ('PD 3')
xlabel ('ISI #')
ylabel ('ISI (s)')
axis ([0,500,0.8,1.2])
disp ('PD 03 DONE')

y =Data.StrideTimeIntervals_15minTrial.PD(:,4);
subplot (3,4,4),plot (y, 'r')
title ('PD 4')
xlabel ('ISI #')
ylabel ('ISI (s)')
axis ([0,500,0.8,1.2])
disp ('PD 04 DONE')

y =Data.StrideTimeIntervals_15minTrial.PD(:,5);
subplot (3,4,5),plot (y, 'r')
title ('PD 5')
xlabel ('ISI #')
ylabel ('ISI (s)')
axis ([0,500,0.8,1.2])
disp ('PD 05 DONE')

y =Data.StrideTimeIntervals_15minTrial.PD(:,6);
subplot (3,4,6),plot (y, 'r')
title ('PD 6')
xlabel ('ISI #')
ylabel ('ISI (s)')
axis ([0,500,0.8,1.2])
disp ('PD 06 DONE')

y =Data.StrideTimeIntervals_15minTrial.PD(:,7);
subplot (3,4,7),plot (y, 'r')
title ('PD 7')
xlabel ('ISI #')
ylabel ('ISI (s)')
axis ([0,500,0.8,1.2])
disp ('PD 07 DONE')

y =Data.StrideTimeIntervals_15minTrial.PD(:,8);
subplot (3,4,8),plot (y, 'r')
title ('PD 8')
xlabel ('ISI #')
ylabel ('ISI (s)')
axis ([0,500,0.8,1.2])
disp ('PD 08 DONE')

y =Data.StrideTimeIntervals_15minTrial.PD(:,9);
subplot (3,4,9),plot (y, 'r')
title ('PD 9')
xlabel ('ISI #')
ylabel ('ISI (s)')
axis ([0,500,0.8,1.2])
disp ('PD 09 DONE')

y =Data.StrideTimeIntervals_15minTrial.PD(:,10);
subplot (3,4,10),plot (y, 'r')
title ('PD 10')
xlabel ('ISI #')
ylabel ('ISI (s)')
axis ([0,500,0.8,1.2])
disp ('PD 10 DONE')

y =Data.StrideTimeIntervals_15minTrial.PD(:,11);
subplot (3,4,11),plot (y, 'r')
title ('PD 11')
xlabel ('ISI #')
ylabel ('ISI (s)')
axis ([0,500,0.8,1.2])
disp ('PD 11 DONE')

y =Data.StrideTimeIntervals_15minTrial.PD(:,12);
subplot (3,4,12),plot (y, 'r')
title ('PD 12')
xlabel ('ISI #')
ylabel ('ISI (s)')
axis ([0,500,0.8,1.2])
disp ('PD 12 DONE')

How would I use a loop to repeat the subplots after the first one.

for col = 1 : 12
    y =Data.StrideTimeIntervals_15minTrial.PD(:,col);
    subplot(3,4,col);
    plot(y, 'r');
    title( sprintf('PD %d', col) );
    xlabel('ISI #')
    ylabel('ISI (s)')
    axis([0,500,0.8,1.2])
    fprint('PD %d DONE\n', col);
end

What would the full line of code look like? I tried to run the code provided above and it didn't give me the same plots.

[Walter Roberson]

The full code would look like,

figure
for col = 1 : 12
    y = Data.StrideTimeIntervals_15minTrial.PD(:,col);
    subplot(3,4,col);
    plot(y, 'r');
    title( sprintf('PD %d', col) );
    xlabel('ISI #')
    ylabel('ISI (s)')
    axis([0,500,0.8,1.2])
    fprint('PD %02d DONE\n', col);
end

The only difference is now I put the leading 0 into the PD DONE message to replicate "PD 09 DONE" instead of the "PD 9 DONE" that my previous version would have generated.

What differences are you observing in the plots?

Have you considered plotting everything on the same plot using

plot(Data.StrideTimeIntervals_15minTrial.PD);
xlabel('ISI #')
ylabel('ISI (s)')
legend({'PD 01', 'PD02', 'PD03', 'PD04', 'PD05', 'PD06', 'PD07', 'PD08', 'PD09', 'PD10', 'PD11', 'PD12'})
