[NTG-context] combination trickery - help needed

Hi, in the attachment is an example file which describes best what i want do. The method with \offset and \clip to place the figures where i want is really brutal force i think. Especially fiddling around with dimension to get the "right fit“ is tedious. Is there a better solution to do such a start/stopcombination? Floatplacing is also influenced by the offset command but i compensated this with *hang - nevertheless all in all i think no good solution. Please help. best regards Bernhard
