I have soil moisture (x) data in the first column and correlation(y) data in the second column. I want a moving average line through the scatter plot of x and y data.I am getting a line which is connecting all the points which seems quite wrong.

Can somebody help me with this?

Thank you so much.

Moving average how many points? What have you tried and what seems to be wrong?

It's not clear to me what exactly do you want to achieve.

You say 10 points, but you use N=8.

"I want to see how moving average will look like with x y data. "

Do you mean like this?

load DATA.mat

x = DATA(:,1);

y = DATA(:,2);

scatter(x,y,'xr')

N = 8;

%Moving mean of both x and y data

arr=movmean(DATA,N,1);

hold on

plot(arr(:,1),arr(:,2),'b-')
