There is a difference in behaviour between PAW and ROOT in function
normalization after it was fit to a histogram. In PAW I get the same
sum of weigths for a function and a histogram. In ROOT function is
visualized by default in a 100 bin histogram, independend of the number
of histogram bins. Then the two sums of weights differ.
If the above is true it should be either changed or a warning somewhere
should be placed.
