change the ploted node location every 1 second

suppose i plot some nodes on the graph and i wish to change the node location every second .

 node=20;
 area=100;
 X=rand(1,node)*area;
 Y=rand(1,node)*area;
 for i=1:node
    plot(X(i),Y(i));
    text(X(i),Y(i),num2str(i));
 end

Singh - if you want to change the location of the kth node, then consider keeping an array of handles to each of the graphics objects returned by plot and text so that you can change the data (position of the node) at will. For example,

 figure;
 hold on;

 node=20;
 area=100;
 X=rand(1,node)*area;
 Y=rand(1,node)*area;

 hPlots = [];
 hTexts = [];

 for k=1:node
    hPlots(k) = plot(X(k),Y(k));
    hTexts(k) = text(X(k),Y(k),num2str(k));
 end

Now change the 4th node position by doing the following

 set(hPlots(4),'XData', 10, 'YData',10);
 set(hTexts(4),'Position', [10 10 0]);

Try the above and see what happens!

thanks

 But Geoff Hayes,I wish all node location will be change every second and    it is not change manually

[Geoff Hayes]

How do the node positions change if not manually? Or do you have an algorithm that does this for you?

Geoff Hayes, I have some solution to change location of each node every second but i am confused with this code can you solve this solution. if yes,then send me your mail ill be send you code.

[singh]

Geoff hayes, i have some code which change the location but i did not get good result because code is so confuse. if u can help me plz send ur email id

[Geoff Hayes]

Singh - please post the code that you have written and describe the problems that you are observing with it.
