In the attached Qlikview, (with this data model):
LOAD * INLINE [
Category, Subcategory, Value, PosOrNeg
Fruit, Apple, 3, Positive
Fruit, Banana, -2, Negative
Vegetable, Carrot, 3, Positive
Vegetable, Pea, 1, Positive
Vegetable, Tomato, -5, Negative
];
I want to analyze exclusively positive values, so filter on "Positive"
(I also may ignore Peas so I only have Apples and Carrots)
Either way, I can see outer pie ring on the lower-right.
But when I filter on exclusively Negative values, I can no longer see the outer pie ring on the lower-right:
]
I can understand why these things don't support both positive and negative values.
And I know Block charts can't render when values are negative even if a single-level pie chart does work.
But must I accept that a nested pie won't work?
I guess a workaround is to wrap in FABS()?
