Histogram: Normalised Occurrence Frequency

by hazel <hazel.kenyon@[EMAIL PROTECTED] > Feb 28, 2008 at 07:28 AM

Hi All,

I want to plot a histogram where the number of samples in each bin are
normalised by the total number of samples across all bins.

Currently I use David's 'HISTOPLOT' and the REVERSE_INDICIES keyword
to get the indicies in each bin. Then Jaco's HISTOBIN to count these
for each bin.

Then I normalise the bin totals and have to plot number of bins vs.
normalised values using Plot and Psym=10.

Is there an easier way to do this? Also how would I use HISTOPLOT to
replot this normalised hist as I can't seem to get it to work.

Thanks,


Hazel
