trying to plot my lab result, but the first data point suppose to be (0,0) , can't make matlab plot that....does this happen to everyone?

function phase_freq(f1,p1,f2,p2,f3,p3,f4,p4,f5,p5,f6,p6,f7,p7,f8,p8,f9,p9,f10,p10)
   f(1)=f1;
   f(2)=f2;
   f(3)=f3;
   f(4)=f4;
   f(5)=f5;
   f(6)=f6;
   f(7)=f7;
   f(8)=f8;
   f(9)=f9;
   f(10)=f10;
   p(1)=p1;
   p(2)=p2;
   p(3)=p3;
   p(4)=p4;
   p(5)=p5;
   p(6)=p6;
   p(7)=p7;
   p(8)=p8;
   p(9)=p9;
   p(10)=p10;
    for i = 1:10
       phase(i) = (p(i)/f(i))*360;
    end
    F = [0 3.3 3.76 7.56 11.40 15.29 19.23 23.21 27.24 31.32];
    plot(F,phase,'-.r*')
    xlim([0 32]);
    xticks(F);
    %xticklabels({'0','3.3', '3.76' '7.56', '11.40', '15.29', '19.23', '23.21', '27.24', '31.32'});
    
xlabel('frequency difference in khz')
ylabel('steady state phase difference')
