No problem… sounds like you need another level of selection for some KPAs. Why not create a KPI Name combobox and use dynamic vis to only show the secondary selector when a KPA Name is selected that has multiple KPI Names?
Well, it is a little hard to explain in a text box. Use an array like
KPA select | Seq | Multi-KPI Names
Texas 1 X
New York 2 X
California 3
Alabama 4 X
…
then vlookup that returns Seq # and if Multi = X then display KPI combo selector.
then have a second array setup to provide
Seq | KPI1 | KPI2 | KPI3 | KPI4 | and so on…
1 Dallas San Antonio Ft Worth Houston
2 Albany New York Buffalo Syracuse
4 Mobile Birmingham Huntsville Montgomery
Then another Vlookup to pull the KPI list for the selector labels…
Then connect the selector outputs to pull the chart data and to feed the selected KPI label to the Y axis…
A little quick and sloppy but may give you an idea…
