Having issues with plotting

I keep getting: error using plot vectors must be the same length Not sure what I am doing wrong

I'm trying to plot this: the x-axis ranges from 0-1000 in intervals of 200 and on the y axis I am trying to plot values from a matrix that is 1row*1000columns

clear,clc

load('DATA_01_TYPE01.mat')

A = sig;

x = A(2,1:1000)

t=0:200:1000;

subplot(3,1,1)

plot(t,x)

clear,clc
load('DATA_01_TYPE01.mat')
A = sig;
x = A(2,1:1000)
t= 0:200:1000;
subplot(3,1,1)
plot(t,x)

for plot, length of x and y must be same. You try

length(t)
length(x)

then you will notice they are different, x has 1:1000 which is 1000 elements, but t=0:200:1000, only have 5 elements.

if you try code below, you will get the plot without error

clear,clc
load('DATA_01_TYPE01.mat')
A = sig;
x = A(2,1:1000)
t=1:1:1000;
subplot(3,1,1)
plot(t,x)

because now both t and x have the same length which is 1000.

Awesome thanks! So is there a way though where I can get the x axis to be in intervals of 200?

Sure. refer to my code below

clear,clc
load('DATA_01_TYPE01.mat')
A = sig;
x = A(2,1:1000)
t=1:200:1000;
subplot(3,1,1)
plot(t,x(t))
