fix: proper histogram boundaries sort

[AndrewGrachov]

Which problem is this PR solving?

• Proper sort of histogram boundaries

Short description of the changes

• Well known javascript behaviour, when array sort is being implemented by lexicographical order, not number,
  so [200, 1000, 300, 1500] instead of [200, 300, 1000, 1500] becomes [1000, 1500, 200, 300]
