how to have the same shape on matlab?

Hello everyone, I got the first figure in another software, and I wish to have the same result on matlab. I get a shape that is close to the desired result but not the same ... Help me please.

dataset=xlsread('tabl.xlsx','tableau','B2:C131');
x=dataset(:,1);
y=dataset(:,2);
[t,r] = cart2pol(x-mean(x),y-mean(y));
polarplot(t, r, '-g');

you will find attached the form I want, the form I get and the table of data.

I suspect both the figures are the same (maybe wrong) just the scalings are different .
