Question

I have a list of int values:

List<int> histogram;

How do I normalize all values so that the max value in the list is always 100?

Answer 1

Iterate though, find the maximum value (call it MAXVAL), then iterate through once more and multiply every value in the list by (100/MAXVAL).

var ratio = 100.0 / list.Max();
var normalizedList = list.Select(i => i * ratio).ToList();
