In the bar view:
Fairly often one would like to stack a number field into non-linear bands. The solution to this at the moment is to create another field with the banding you need.
When dealing with a file of several million rows however, this has a very substantial impact on memory and file size.
It would be more efficient if there was some kind of option when stacking to specify banding rather than just the automatic linear split.

Options required would be.
number of bands
value 'from' and 'to' for each band.
