loop with subplot in MATLAB

I have data sets in the cell. Then I want to deal with those data sets. I have included my sample code here below. I want to plot acceleration, velocity, and displacement for each data set. This code partially worked for the last subplot, and I see only the acceleration plot for the others. Help, please.

acceleration={[10;12;14] [6;8;9] [8;12;18]};
t=[1;2;3];
N=3;
for i=1:N
    figure
    subplot(3,1,1)
    plot(t,acceleration{1,i},'-b')
end
velocity = cell(1,N);
for i=1:N
        velocity{1,i}= cumtrapz(t,acceleration{1,i});
        subplot(3,1,2)
        plot(t,velocity{1,i},'-g')
end
displacement = cell(1,N);
for i=1:N
        displacement{1,i}= cumtrapz(t,velocity{1,i});
        subplot(3,1,3)
        plot(t,displacement{1,i},'-r')
end

The first loop creates a figure for each cell, but the next too loops don't. Did you want a figure for each cell?

acceleration={[10;12;14] [6;8;9] [8;12;18]};
t=[1;2;3];
N=3;
for i=1:N
    figure(i)
    subplot(3,1,1)
    plot(t,acceleration{1,i},'-b')
end
velocity = cell(1,N);
for i=1:N
    figure(i)
    velocity{1,i}= cumtrapz(t,acceleration{1,i});
    subplot(3,1,2)
    plot(t,velocity{1,i},'-g')
end
displacement = cell(1,N);
for i=1:N
    figure(i)
    displacement{1,i}= cumtrapz(t,velocity{1,i});
    subplot(3,1,3)
    plot(t,displacement{1,i},'-r')
end

Alternatively, shorten the code to do this in one loop:

acceleration={[10;12;14] [6;8;9] [8;12;18]};
t=[1;2;3];
N=3;
for i=1:N
    velocity{1,i}= cumtrapz(t,acceleration{1,i});
    displacement{1,i}= cumtrapz(t,velocity{1,i});
    
    figure(i)
    subplot(3,1,1)
    plot(t,acceleration{1,i},'-b')
    subplot(3,1,2)
    plot(t,velocity{1,i},'-g')
    subplot(3,1,3)
    plot(t,displacement{1,i},'-r')
end

Even better, use tiledlayout/nexttile instead of subplot!

acceleration={[10;12;14] [6;8;9] [8;12;18]};
t=[1;2;3];
N=3;
for i=1:N
     velocity{1,i}= cumtrapz(t,acceleration{1,i});
     displacement{1,i}= cumtrapz(t,velocity{1,i});
     
     figure(i)
     tiledlayout(3,1)
     nexttile(1)
     plot(t,acceleration{1,i},'-b')
     nexttile(2)
     plot(t,velocity{1,i},'-g')
     nexttile(3)
     plot(t,displacement{1,i},'-r')
end
