data = dlmread('value.txt');
plot3(data(:,1),data(:,2),data(:,3),'r.')
axis off
[x,y,z] = ginput(2)
ginput gives value in command window. I want that value above cursor on image when i select point. So, how to do..?

Add an axes or lineseries ButtonDownFcn callback (if you add it to axes, be sure to set() 'Hittest', 'off' on all the lines in the axes)
