At this moment we can’t seem to find a possibility to group the columns and/or rows based on an interval.
This is a highly wished feature since we would like to narrow down the produced columns and rows by using this kind of interval.
See this very simple example. This kind of functionality is needed for rows and columns.
Thank you for your interest in Flexmonster Pivot!
Currently, there is no such feature. We have added it to our backlog and will consider it when planning our future major releases.
Please let me know in case of any other questions.
