Plot part of data

I have data like this: t Amp 0.00000 0.14216 0.02000 0.14648 0.04000 0.15523 0.06000 0.16035 0.08000 0.17030 0.10000 0.17817 0.12000 0.22207 0.14000 0.29376 0.16000 0.35582 0.18000 0.39803 0.20000 0.44485 0.22000 0.46390 0.24000 0.47957 0.26000 0.46590 0.28000 0.43250 0.30000 0.38545 0.32000 0.33179 0.34000 0.27900 0.36000 0.23127 0.38000 0.18947 0.40000 0.15524 But I want to plot the data only for 0 - 0.2000 second.

How to make a coding program for this.

Thx

plot(t.Amp(t.Amp<0.2000))

Have you loaded your date into Matlab yet? If so what structure is it in?

[Skydriver]

This is my coding : figure(999); grid on plot(t31(1:102,1), t31(1:102,2)).

I made a limit of data base on number of row.

[Kevin Chng]

   figure(999); 
   grid on 
   plot(t31(1:102,1), t31(1:102,2))

plot(t.Amp(t.Amp<0.2000))

[Kevin Chng]

try

 figure(999); 
 grid on 
 x = t31(1:102,1);
 y = t31(1:102,2);
 plot(x(x<=0.2), y(x<=0.2))
