matlab showing only points not line. how to connect it?

function[x]= ap(p)
n=1;
x=0;

while ( n<=p)

      sum=0;
      m=n;
      while (m>0)
          sum = sqrt(sum+m);
          m=m-1;
      end
      x= sum;
     plot(n,x,'o')
      n=n+1;

      hold on
      grid on

x

1 = input('Enter the length of x1 : ');
y1 = input('Enter the length of y1 : ');
x2 = input('Enter the length of x2 : ');
y2 = input('Enter the length of y2 : ');
x = linspace(x1,y1);
y = linspace(x2,y2);
line (x,y)

Answer 1

[ehsan rastgar]

hi dear just change this part

    % plot(n,x,'-o') or use plot(n,x,'_o')

[APURVAKUMAR SHARADKUMAR JANI]

Tried already. Not working

[APURVAKUMAR SHARADKUMAR JANI]

here is the graph

[Priyank Vithani]

x1 = input('Enter the length of x1 : ');
y1 = input('Enter the length of y1 : ');
x2 = input('Enter the length of x2 : ');
y2 = input('Enter the length of y2 : ');
x = linspace(x1,y1);
y = linspace(x2,y2);
line (x,y)

Answer 2

[Walter Roberson]

function[x]= ap(p)
n=1;
x=0;

while ( n<=p)
      sum=0;
      m=n;
      while (m>0)
          sum = sqrt(sum+m);
          m=m-1;
      end
      x(n) = sum;
      n=n+1;
  end
  plot(1:p,x,'o')
  grid on

[APURVAKUMAR SHARADKUMAR JANI]

Still only dots are coming up

[Walter Roberson]

plot(1:p,x,'o-')

[Priyank Vithani]

x1 = input('Enter the length of x1 : ');
y1 = input('Enter the length of y1 : ');
x2 = input('Enter the length of x2 : ');
y2 = input('Enter the length of y2 : ');
x = linspace(x1,y1);
y = linspace(x2,y2);
line (x,y)

[Walter Roberson]

That input code does not have any apparent relationship to the function you posted. The function you posted expects a single scalar input that is probably intended to be a positive integer.
