I have an answer to point one... It seems that if you blend on Product Category as well, but do not really use it in detail in your map, you get a label per product category. So your labels are hard to read because they consist of three texts on top of each other and the texts are not the same.
Try unclicking the link in your secondary data source next to Product Category and that seems to clear it up.
Your other questions I didn't quite understand. Sorry.
Hope this helps though.
For Question #1 You need to do something like
CF#1 STR([Comp Shr YoY])
CF#2 STR([Comp X share])
Then [CF#1]+" insert carriage return "+[CF#2]
For your label
I have tried this but it don't work.. plus I need to do some other calc to get % instead of high decimal numbers...
Maybe there is other way to create map chart showing share for one comp, YoY and possibility to filter down by seg and prod.
