I'm not sure what's meant by normalising either. My only suggestion would be, if your bars are not all the same width, then you would need to create a frequency DENSITY histogram, which gives a better picture of what is really happening.

Hi Prove It,
Thanks for your answer. So searching this a bit more it seems that normalizing a histogram means I'm creating a PDF?
If so am I correct in saying I'll take my data in excel and divide the frequency counts by the total number of counts?
Great thanks
Related question:
I have data for three related graphs (increasing the node density) and showing the pdf of the link duration as the node density is increased.
However when I get the data it comes with the bin and the frequency.
The problem is the bins used for each of the three node densities are different.
I need the x axis to be consistent. I think however that by modifying this I am effectively modifying the mean of the graphs.
Is there someway I can modify all of these (suing something like excel) so they all use the same bins without having access to the raw data?
Thanks
