square=x*x’;

sx=sum(x);
sy=sum(y);
N=10;
a=(N*d-sx*sy)/(N*square-sx^2);
b=(square*sy-sx*d)/(N*square-sx^2);

xx=0:25;
yy=a*xx+b;
plot(x,y,’o’,xx,yy)
axis([0 25 0 15])

ylabel(‘y’)
variabel square merupakan penampung dari hasil dari , d adalah , sx adalah jumlah dari x, dan sy adalah jumlah y. Hasil yang ditampilkan MATLAB seperti berikut ini:
a =
0.4446
b =
2.4318

Anything wrong with it? Your plot looks fine:

What do you mean by "in gui"? Your data and fit are showing up in a figure window. What else do you want? Please give explanation or sample screenshot.

Perhaps what you want to know is cftool; that You can run from command window (>> cftool %enter) and the input x, and y data. You can also pick the type of fitting.
Hope this help
