i still need some more help. see, when i draw the error bars , theres not much difference between my worst acceptable line and best fitt line.. moreover i there any quicker way of finding the gradients of the lines, cuz its extrememely nerve-wrecking to count each and everypoint accurately. its also very hard to plot the error bars :(.. what am i doing wrong?
