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

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.

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

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