Rangesum problem in barchart

[paulcalvet]

Hello,

I have a problem with rangesum(above

My dataset is :

Machine	EM5 Zone brossage
Année/Semaine	(RangeSum(Above(Sum([Temps de bon fonctionnement]), 0, RowNo())))	(RangeSum(Above(Sum([Nb pannes]), 0, RowNo()))+1)	(RangeSum(Above(Sum([Temps de bon fonctionnement]), 0, RowNo()))) / (RangeSum(Above(Sum([Nb pannes]), 0, RowNo()))+1)
2020/01	9.14	1	9.14
2020/02	10.86	13	0.835384615
2020/03	52.22	20	2.611

Machine	EM5 Zone sablage
Année/Semaine	(RangeSum(Above(Sum([Temps de bon fonctionnement]), 0, RowNo())))	(RangeSum(Above(Sum([Nb pannes]), 0, RowNo()))+1)	(RangeSum(Above(Sum([Temps de bon fonctionnement]), 0, RowNo()))) / (RangeSum(Above(Sum([Nb pannes]), 0, RowNo()))+1)
2020/01	9.14	1	9.14
2020/02	14.53	4	3.6325
2020/03	58.14	7	8.305714286

But when I put the formula in red in a barchart, I have this values : 

For the machine EM5 Zone sablage, I have 4.61 !

If I select this machine, I have the value 8.31 which is the good value (the same value than in the table) :

I haven't this problem when I select the other machine 😞

please help !
