Plotting lines from random number generators

Hi,

I need help with visualizing a set of data that i generated in MATLAB to represent discrete fractures. I made use of random number generators to get the fracture centers and also have other vectors representing the orientation(angle i want the line to be tilted through), length of the line through the center point and width of the line. I've had a hard time getting to visualize this data in MATLAB.. Can anyone please help? My code sample is attached

      k= 3.4;             
      Density = 1.5;    
      Mu = 0.;            
      Sigma = 0.7;         
      Length = 75;        
      Lambda = 2*Density*Length; 
      N = floor(Lambda); 
    Center = poissrnd(Lambda,2,N);     
    Radii = lognrnd(Mu,Sigma, N, 1);   
    Aperture = 0.004*sqrt(Radii);      
    d = rand(N,1);                     
    f = exp(k) - (2* d.*sinh(k));      
    Angle = acos(log(f)/k);            
    Newradii = 2500*Aperture;    % To aid visualization of fractures
    x = (Center(1,:)- Lambda)';
    y = (Center(2,:)- Lambda)';
    % section for visualization..
      for i = 1: N
        plot(x(i), y(i),'go' , 'MarkerSize',Newradii(i))
        hold all
       end

How do i inculcate orientations into the plot generated? and this present code plots the points as circles.. i want them as straight lines.

Thanks.

I don't quite understand what you mean by plotting them as straight lines, do you want to connect them to the center? If so, just do

plot([Center(1,i) x(i)],[Center(2,i) y(i)]);

As to the direction, you can take a look at the quiver function
