Another +1 for plots, in particular a scrolling plot widget. I maintain a bit of scientific software for University and they all use real-time scrolling line charts. The basic requirements are * good performance (Christians was the best performing of those I tried) * multiple traces * autoscale * independently (of incoming data) adjustable scrolling speed * introspectable / usable from python[1] > MENU BUTTON > A GtkButton that shows a menu when clicked (and handles positioning, > etc).

(I know the fullscreen toolbar used to have it at least). And this too (if you are describing the wrench menu on chrome for example). John [1] Access from python because they get used in association with numpy, which is used for the static plots. In the end I chose to maintain a fork of the old rtgraph pygtk package https://github.com/nzjrs/rtgraph _______________________________________________ gtk-devel-list mailing list gtk-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-devel-list
