How to plot random (x,y) coordinates on a plot? if X and Y has different values in array form ?And join all these (X,Y) coordinates to from a connected network graph?

 x =
    8.7749
   15.3103
    3.7375
    8.9117
    5.5205
   13.1020
   19.1949
   10.1191

 y =
    7.6312
   15.9040
    9.7953
   12.9263
   13.5941
    3.2522
    6.8077
   13.9815

(x(1),y(1))=(8.7749, 7.6312)
(x(2),y(2))=(15.3103, 15.9040).......
(x(8),y(8))=(10.1191,13.9815)

connect (x(1),Y(1)) with (x(i),y(i)) where i is 2,3,...8 similarly others points

Not sure what you mean. Do you simply want to plot a line from every (x,y) point to every other (x,y) point? Or do you want to form a graph or directed graph object? (Look up graph() in the help).

a connected graph connecting all the (x,y) points formed by above-given diff X and Y values

Sneha - you will want to iterate over each pair of coordinates and draw a line between each one. For example, you could do

hConnections = [];
close all;
figure;
hold on;
hNodes = plot(x,y,'ro');
for p=1:size(x,1)-1
    for q=p+1:size(x,1)
        hConnections = [hConnections ; line([x(p);x(q)], [y(p);y(q)])];
    end
end

The hNodes and hConnections are just the handles to the drawn nodes and connections respectively.

you can use this code for displaying any data in the form of [x, y, f(x,y)] or data with coordinate
