Edited Unassigned: how to use pieofpie [15203]

Hello all,
I need to represent two groups of the same data in a unique graph, if possible.
A pie (TOTAL_DATA) with a normal row (Item), column(Nr) data
and another pie (GROUPED_DATA) with the same data grouped.

TOTAL_DATA:
Item ......................................... Nr
Item_ONE ..................................12
Item_TWO..................................45
item_THREE...............................14
item_FOUR.................................62
item_FIVE....................................98

GROUPED_DATA:
Item ......................................... Nr
item_NOK...................................71 ----> (Item_ONE + Item_TWO + Item_THREE)
item_OK.....................................160 ---->(Item_FOUR + Item_FIVE)

The goal is to show how many % the GOOD items represents inside all data.

So I thought use PieOfPie graph but there's no documentation to do this. Could anyone show a sample how to use PieOfPie chart? Or there's another way to represent this situation?

Thanks in advance
