Sorry that I forgot to add this. Shame.
I would like to apply these mathematical functions on the original values
stacked in the respective bins.
For instance:
The sample data measures the wight of an animal.
1) historam give a count of how many values are in each bin.
I would like to calculate the average wight of all animals
sorted in bin1, bin2 etc.
This is also useful in where you have a time component.
In Spreadsheets I would use a '=' to reference to the original data and then
either sum it up or count it per class.
I hope this is somehow understandable.
Thanks,
Timmie
