I am new to Matlab and I've been plotting for a while, but now I would like to plot 100 specific samples obtained from a temperature sensor within 100 seconds.

y=[20.50,20.50,20.50,20.50,20.50,20.50,20.60,20.60,20.60,20.60,20.60,20.60,20.60,20.60,20.60,20.60,20.60,20.60,20.60,20.60,20.60,20.60,20.60,20.60,20.60,20.620.60,20.60,20.60,20.60,20.60,20.60,20.60,20.60,20.60,20.60,20.60,20.70,20.70,20.60,20.60,20.70,20.70,20.60,20.60,20.60,20.60,20.60,20.60,20.60,20.60,20.60,20 60,20.60,20.60,20.60,20.60,20.60,20.60,20.50,20.50,20.50,20.50,20.40,20.40,19.80,19.80,19.00,19.00,18.40,18.40,18.20,18.20,17.80,17.80,17.30,17.30,16.90,16.9 16.60,16.60,16.30,16.30,16.20,16.20,16.20,16.20,16.00,16.00,15.60,15.60,15.40,15.40,15.10,15.10,14.60,14.60,14.40,14.40]
The Y-Axis would be "Temp

erature" and the X-axis would be "Time" which has a duration of 100 seconds. My question is how can I establish an X-axis of 100 values without having to write something like the Y-Axis 100 times:

x=[1,2,3,4,5,6,7,8,9...]

Hi,

This should fix your problem,

y=[20.50,20.50,20.50,20.50,20.50,20.50,20.60,20.60,20.60,20.60,20.60,20.60,20.60,20.60,20.60,20.60,20.60,20.60,20.60,20.60,20.60,20.60,20.60,20.60,20.60,20.620.60,20.60,20.60,20.60,20.60,20.60,20.60,20.60,20.60,20.60,20.60,20.70,20.70,20.60,20.60,20.70,20.70,20.60,20.60,20.60,20.60,20.60,20.60,20.60,20.60,20.60,20 60,20.60,20.60,20.60,20.60,20.60,20.60,20.50,20.50,20.50,20.50,20.40,20.40,19.80,19.80,19.00,19.00,18.40,18.40,18.20,18.20,17.80,17.80,17.30,17.30,16.90,16.9 16.60,16.60,16.30,16.30,16.20,16.20,16.20,16.20,16.00,16.00,15.60,15.60,15.40,15.40,15.10,15.10,14.60,14.60,14.40,14.40];
x = 1:1:100;
plot(x,y)
