I have never thought about having the legend to contains meaningfull object.Are you suggesting something like: #addColor:object:text: that will collocate the object being the legend label and colored box?
Yes. I'd like a way to specify the object, and either a block or selector to get its display string. It all came quite by accident. Since you can drag the legend around, I started thinking of it as a live object. So I clicked on one of the labels, and the label's text appeared in the right-most pane of the GT Inspector. Then I thought, "if I put the underlying domain objects in the legend, shouldn't I then be able to inspect them in GT?!" And it worked!

Maybe the names are not properly chosen. If you have better ones, would be great :-)
Ah, now I see. I will think about the names...
I am not sure to understand. Which text builder are you referring to?
Sorry, that was /way/ OT. I was dreaming about constructing visualizations by direct manipulation instead of coding.
