[Moose-dev] Problem adding avatars around an arc

Hi all :-), I have been playing with some mockups for an idea now that I have finally the time for it. As usual I start with a hand drawn mockup like this: https://d167tapqdyj68f.cloudfront.net/offray.withknown.com/e/e/4/e/ee4e49f2… and the I start to code the pieces with dummy data. Here is, for example, what I call the avatar wheel: And the arcs of it could be surround by objects that, as you can see in the mockup, could be scaled and "pilled" as they go. The surround part is working, "individully" as the following couple of examples show: But, when I try to compose both surrounding avatars into the same view and arc, things get weird: I don't know if some one could take a look into the code or propose a debug strategy to see what's going on. The code is in the DataViz package[1] and the playground for running the failing visualization or to be edited it to get the working ones is at 2 [1] http://smalltalkhub.com/#!/~Offray/Dataviz [2] http://ws.stfx.eu/EX4NR2XBM0G0 Thanks, Offray
