Bug#441998: 3D piled up area diagram: problem with positive and negative numbers

Package: openoffice.org-calc
Version: 2.2.1-8
Severity: normal

I noticed that with 3D piled up area diagram there are problems with positive 
and negative numbers. I mean: if I have a table like the following one:

	Value1	Value2	Value3	Value4
01/07	20.441	1.538	940	-144
02/07	17.452	-3.136	1.826	734
03/07	14.881	-3.144	3.241	1.320
04/07	12.673	-3.366	4.112	2.054
05/07	11.102	-2.836	5.259	5.172

... in the 3D piled up area diagram I see negative values like if they were 
positive ones and the sum of them is then not correct (it would be if they 
were positive).


Hope this helps,
  Matteo
