Using probability paper for a normal distribution

[sunrah]

I have to compare measurements in a normal distribution with a theoretical gauss curve on "probability paper" (the y-axis has percent). Does anyone know any online guide/ information?

thanks, have wasted the last three hours on this

I found some useful websites for future reference:
http://reliawiki.org/index.php/Probability_Plotting

http://www.engineeredsoftware.com/nasa/pe_median.htm

for normally distributed data I ended up plotting

$\frac{i - 0.3}{n + 0.4}$

on the vertical which is the median rank corresponding to the i^th measurement, which was plotted on the horizontal. result should be linear for good normal distribution of data.
