[Pharo-users] Making a bitmap area proportional to a value

Hi, I can arrange elements in a visualization where the size/area of an RTBox is proportional to a specified value, like here: or I can made all avatars (RTBitmaps) appear into this one: But I would like to combine both, making the avatars area proportional to a given value and present them in a RTFlowLayout. Is this possible and how? Thanks, Offray
