I'm trying to implement natural hierachies with QV 10 (f.e. Year-Quarter-Month or Country-Region-City) and I'm searching some articles or samples.
In particular, for the temporal hiearchy Year-Quarter-Month (read from a Calendar or Time table) can I create only an unique list box as a tree view to select a year and expand the quarters and then the month? How?
In the graph that shows f.e. the invoices amount, do I organize the temporal dimension by creating a drill-down group?
Many thanks for your suggest.
