MATLAB: Is the subplot in for loop only plotting in one of the figures

for loopMATLABsubplot

Hi! I'm trying to figure out why my code isn't working? My code is only displaying the values in the second subplot, and I don't know why it does that?
 level = 1:25;
streakvalue = [0 60 120 180 240 300 360 420 480];
for i = 1:length(streakvalue)
    hold all
    old = 110 + streakvalue(i) + level * 9.9;
    subplot(1,2,1);plot(old,level);yticks(1:2:25);grid on
    new = 100 + streakvalue(i) + level * 8;
    subplot(1,2,2);plot(new,level);yticks(1:2:25);grid on
end

Best Answer

The behavior of the "hold" command is sometimes a little counterintuitive.
Try this
level = 1:25;
streakvalue = [0 60 120 180 240 300 360 420 480];
figure
for i = 1:length(streakvalue)
    old = 110 + streakvalue(i) + level * 9.9;
    subplot(1,2,1); hold all; plot(old,level); yticks(1:2:25);grid on
    new = 100 + streakvalue(i) + level * 8;
    subplot(1,2,2); hold all; plot(new,level); yticks(1:2:25);grid on
end
