plot figure from a vector saved from a for cycle

hi, i am saving a vector from a for cycle but when i try to plot all te saved value on the figure it appears just the last value of the plot.

this is the script

 rep1 = [1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26];

for i = 1:length(rep1);

name=['TimeHistory_',int2str(rep1(i)), '.dat'];

fid = fopen( name, 'r');

if fid==-1;disp(msg);end [time,dispVR,dispVL,P15,Temp,RH,Fs]=importdata(fid);

[dispV,dispV_h,y01,y01_h,f_spec,f_v01,y01_h_m,zeta,zetair]= signalprocess1(time,dispVR,dispVL,P15,Temp,RH,Fs);

[U,Re,dinvisc,Umean]=reference (P15,Temp,RH);

peak = max(dispV) + abs(min(dispV));

RMS = sqrt(rms(dispV));

out (i,:) = [zeta zetair f_v01 Umean Re peak RMS];

Re_vec (i)= [Re];

Peak_vec (i)= [peak];

RMS_vec (i)= [RMS];

end

% Plot peak to peak over Re

figure()

plot(Re_vec (i), Peak_vec (i))

title('Peak to Peak Displacement')

legend('Peak to Peak', 's')

xlabel('Re')

ylabel('Peak to Peak, [mm]')

please help me

Yep. Use

plot(Re_vec, Peak_vec)

to plot all data. The way you have it set up right now, you only plot the i th data point, which, after running through the loop would be the last one.
