A calculated field similar to the following can be created to get two dimensions:
left(str(avg([Discount]) *100), 4) + "%" + ", $" + left(str(sum([Sales])), 3) + "," + mid(str(sum(Sales)), 4)
And for a dimension and measure:
attr([Fruit]) + "
" + left(str(avg(Percent)*100),4) + "%"
Currently, there is no dynamic way to make the label centered in the middle of the pie. This might be a good one for the ideas section.
Hope this helps!
This is Great! Thanks!
