Using the dual() function to set the sort order of dimensions

The following recipe shows you a way to overcome a problem with the sort order when creating a range dimension. You create a calculated dimension to the group set of values as custom ranges and describe it as with labels such as "above 10", "< 30", "< 60", and "up to 100". If you sort it alphabetically, then it will not show in the same order. We can assign a numeric value to each label using the dual() function. Using this approach, you can simply set the sort order of the dimension as numerical and it will sort correctly.
