Thanks a lot :) .... Thanks for the example :) ... Its crystal clear
now....
I have one more question.... What does 'm' and 'k' mean when they come as
unit in the y axis..... :)

----------------------------------------------------------
Units have divisions. for example: 1200 meters = 1.2 kilometers, or 1200m =
1.2km
0.239Volts = 239 milivolts, or 0.239V = 239mV

The most known divisions are:

T -  TERA - TRILLIONS
G - GIGA - 103 X 103 X 103 (BILLIONS)
M - MEGA - 103 X 103 (MILLIONS)
k - kilo - 103 (THOUSANDS)
--- - normal - 1, 10, 100
m - mili - a milesimal part

?  - micro (the greek letter micron) - a milionesimal part
? - nano (also a greek letter like "n") - a billionesimal part

p - pico - a trillionesimal part
