How to plot 5 rows from a dataset? My dataset size is 125*694. I have to plot 5 rows from there so total 5*694(3470) data point.. Whenever i have plotted this each row placed above of another row. X axis range should be 0-3500 but it shown 0-700

 a = dlmread('EtLAPV_TextData_Class8.txt');
[m n]=size(a);
i=(a(1,:));
plot (i)
hold on
j=(a(2,:));
plot (j)
hold on
 k=(a(3,:));
  plot(k)
  hold on
  l=(a(4,:));
  plot(l)
  hold on
  m=(a(5,:));
  plot(m)
  hold on
 title('Electrode Response')
 xlabel('Measurement points');
 ylabel('Response');

I think there will be some sort of editing by which i can plot these rows only vertically !! Thanks in advance

try the following:

 a= randn(125,694);  % change the randn(125,694)) by  dlmread('EtLAPV_TextData_Class8.txt')
new_a=a(1:5,:); % took only first five rows.
new_a=new_a';   % interchange the row with col.
new_a=new_a(:)  % make it a col. matrix/ vecor.
plot(new_a)

 title('Electrode Response')
 xlabel('Measurement points');
 ylabel('Response');
