Hi,

I have the Moose 5.0 beta and the code using RTPieBuilder is not working properly showed below. There is any way to update Roassal to support this?

Cheers,

Offray

    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

   Hi 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
