PLOT2ORG

PLOT2ORG(X,Y) creates a scatter plot of Y vs. X in which each point is connected to the origin (0,0). X and Y should be equal length vectors.
PLOT2ORG(X,Y,[X0 Y0]) in which X0 and Y0 are scalars connects each point to the origin specified by (X0,Y0).

PLOT2ORG(...,'LineSpec') uses the color, marker and linestyle properties specified by the string LineSpec. See PLOT for possibilities.

H = PLOT2ORG(...) returns a two-element vector with a handle to the scatter points and a handle to the connecting lines.

Example:
% the data
x = 10*rand(10,1)-5 ;
y = 10*rand(10,1)-5 ;
plot2org(x,y,'go-') ;
hold on ;
plot2org(x,y,[mean(x) mean(y)],'r.:')
