Hi, One of the visualization that saw porting is DistributionMap. However, now it does not work at all because menuMorphBlock: is not defined in RTInteractionBuilder. Thus, it seems to me that the visualization was not tried in practice, only refactored in code. This is not a good idea. When modifying such things, please make sure that you know how to produce the visualization and test it. If you encounter problems like the menuMorphBlock:, please bring it to the mailing list to find a solution. Cheers, Doru -- www.tudorgirba.com "Every thing has its own flow"
