Hi!
In that case you can create a normalizer and use it after all the elements have
been added.
For example (__you need to update Roassal since I’ve just fixed a bug__):
-=-=-=-=-=-=-=-=-=
v := RTView new.
data := #((1) (2) (1 2)).
es := data collect: [ :d |
b := RTPieBuilder new.
b interaction popupText.
b objects: d.
b slice: #value.
b build.
b view asElement.
].
v addAll: es.
RTCellLayout new lineItemsCount: 3; on: es.
RTMetricNormalizer new
view: v;
objects: #(1 2);
distinctColor.
v
-=-=-=-=-=-=-=-=-=
If you do not know what are the values you have added in, you cannot provide
“objects: #(1 2)”. In that case, you can simply do:
-=-=-=-=-=-=-=-=-=
v := RTView new.
data := #((1) (2) (1 2)).
es := data collect: [ :d |
b := RTPieBuilder new.
b interaction popupText.
b objects: d.
b slice: #value.
b build.
b view asElement.
].
v addAll: es.
RTCellLayout new lineItemsCount: 3; on: es.
RTMetricNormalizer new
view: v;
elements: v elements;
distinctColor.
v
-=-=-=-=-=-=-=-=-=
Let us know how it goes!
Cheers,
Alexandre
