Lets say my cordinates are as follows x= [0 1 2 3 4 5] y= [0 1 2 3 4 5]
However, i want to set my axis from : x= (-20 ,20) y= (-20, 20) so that I can just see all the 4 quadrants , while my plotted values lies in first quadrant.

Try this:

x=0:5;y=0:5;
plot(x,y);grid on;
set(gca,'XLim',[-20 20]);
set(gca,'YLim',[-20 20]);
