[Pharo-users] history graph widget

Hi I would like to have a Morphic widget like this. Does anyone know if there is something already done that I could reuse? [image: Inline image 1] Maybe do it with Roassal in this way: Use the list morph, where each row knows an image morph with its corresponding slice of the graph. Each time the graph changes (for example, if a node is appended), render using Roassal the part of the graph has to be updated, and cut the rendered surface in the new slices for each updated row. Any opinion? Maybe I should think more in vectors (i.e. Athens) instead of pixels/images? Cheers, Martin
