Hi Hernán,
I did a bit of programming today and did a PieBuilder. Here are some example: -=-=-=-=-=-=-=-=-= b := RTPieBuilder new. b interaction popup. b objects: RTShape withAllSubclasses. b slice: #numberOfMethods. b globalRule distinctColor. b labelledIf: [ :c | c numberOfMethods > 18 ]. b view -=-=-=-=-=-=-=-=-=
-=-=-=-=-=-=-=-=-= | b | b := RTPieBuilder new. b interaction popup. b objects: (Array with: Dictionary with: Collection with: Set with: OrderedCollection ). b slice: #numberOfMethods. b globalRule distinctColor. b labelled. b emphasize: Set by: 20. b emphasize: Dictionary by: 20. b open. -=-=-=-=-=-=-=-=-=
Some example have been added to the Roassal example browser, available from the World menu.
This is just a beginning. I made these example without a clear scenario in mind. If you come with a specific need, probably you will be able to adjust the PieBuilder. For example, you may want to particularize the position of the labeling
Cheers, Alexandre

Thanks Alex,
I did not finished reading the chapter about RTBuilder yet. But regardless of the GraphET2 scope, having a pie diagram builder is important for Pharo (I don't know the status of PieChartMorph but I will check).
I have tried two different directions. One is adding a RTLabel to each sector shape in #getElementsFromModels
GET2PieDiagram>>getElementsFromModels
... label := RTLabel new text: model key. shape := shape + label. ...
| diag | diag := GET2DiagramBuilder new. (diag pieDiagram) function: #value; models: {'A' -> 30 . 'B' -> 10 . 'C' -> 20 . 'D' -> 40}; color: [ Color random ]. ^ diag open.
Another one is using #modelLabels: to add labels to axis:
| diag | diag := GET2DiagramBuilder new. (diag pieDiagram) modelLabels: #key; function: #value; models: {'A' -> 30 . 'B' -> 10 . 'C' -> 20 . 'D' -> 40}; color: [ Color random ]. ^ diag open.
but none of them positions the labels nicely. If anyone wants to comment would be very welcome :) Cheers,
Hernán

Thanks for your effort. This is very valuable. However, I am not sure a pie diagram should be part of GraphET. A pie is radically different from a curve. Maybe subclassing the class RTBuilder is the way to go. You will then not be constraint by GraphET for the labeling...
Cheers, Alexandre

Hello
I am trying GET2 pieDiagram builder. You may want to add a random color in the #pieExample method so it looks nicer (see attachment):
| diag | diag := GET2DiagramBuilder new. (diag pieDiagram) models: #(30 10 20 40); color: [ Color random ]. ^ diag open.
Now my question is simple, but I don't know how to start
How would you add labels to each sector?
Hernán
