Very large "Others" element in some cases in Treemap

[mattab]

In some cases, the Treemap visualisation does not seem to sort items by value before drawing the treemap report. For example there is a large column value (for example in server time: 1000 visits at 22:00 when other hours have 10 visits), and one expects to see this large value (22:00) displayed in the Treemap, yet it shows "Others" very large instead.

-> Should Treemap always sort value in decreasing order before generating the visualisation?
