[NTG-context] Sequentially number figures (even over chapters)

Dear list, I want to number my figures sequentially, even over chapters. With the code below (late(st) minimals and mkiv) %%% Begin example \setuphead[chapter][ page=no, ] \setupcaptions[ way=bytext, prefixsegments=none, ] \starttext \chapter{This is a short chapter} It contains one figure. \placefigure[here][none]{A caption.}{\externalfigure[cow][width=4cm]} \chapter{This is another short chapter} It contains the same figure. \placefigure[here][none]{A caption.}{\externalfigure[cow][width=4cm]} \stoptext %%% End example both figures are called "Figure 1". I would expect the second one to be called Figure 2. Any ideas? Best regards, Mikael
