How i plot these values in Matlab 2015 version?

  Time    Allystar   M8T F9P   LS 
 
  15:27:31  -0.1788  -0.1246  -0.1553  -0.1248 
 
  16:27:31  -0.3784  -0.0922  0.0863  -0.1232 
 
  17:27:31  -0.026  0.0978  0.2577  0.3321 
 
  18:27:31  -0.0607  -0.149  -0.0981  0.0831 
 
  19:27:31  -0.9248  -0.6555  -0.7323  -0.745 
 
  20:27:31  -0.2253  -0.1903  -0.3662  -0.3096 
 
  21:27:31  -0.2381  -0.2125  -0.3155  -0.3181 
 
  22:27:31  -0.4784  -0.4363  -0.2506  -0.4413

readtable().

In your version, those durations will come across as character vectors, and you will not (in your version) just be able to pass them to duration() in order to convert to HMS. However, you can

cell2mat(cellfun(@(s) sscanf(s, '%d:%d:%d', [1 inf]), Table.Variable, 'uniform', 0))

and pass that to duration() [you might have to split the columns into individual arguments.)

Thanks for your responce.

But it shows error.

If i change the time with numerical values then how it works. if posible send to me details programme.

Time Allystar M8T F9P LS

1 -0.1788 -0.1246 -0.1553 -0.1248

2 -0.3784 -0.0922 0.0863 -0.1232

3 -0.026 0.0978 0.2577 0.3321

4 -0.0607 -0.149 -0.0981 0.0831

5 -0.9248 -0.6555 -0.7323 -0.745

6 -0.2253 -0.1903 -0.3662 -0.3096

7 -0.2381 -0.2125 -0.3155 -0.3181

Eek, your version was pretty primitive on reading table formats compared to current versions!

filename = 'allystar.txt';
fid = fopen(filename, 'rt');
tcell = textscan(fid, '%s%f%f%f%f', 'headerlines', 1);
fclose(fid);

t = table(tcell{:}, 'variablenames', {'Time', 'Allystar', 'M8T', 'F9P', 'LS'});
timeparts = cell2mat(cellfun(@(s) sscanf(s, '%d:%d:%d', [1 inf]), t{:,1}, 'uniform', 0));
t.times = duration(timeparts(:,1), timeparts(:,2), timeparts(:,3));

plot(t.times, t.Allystar, t.times, t.M8T, t.times, t.F9P, t.times, t.LS);
legend({'Allystar', 'M8T', 'F9P', 'LS'})
