I'm not aware of one,  but what you describe seems like a stacked bar
chart?  I do not believe Medsphere's Graph2D
<http://medsphere.org/projects/widgets/wiki/Graph> will render a stacked
bar (could be wrong, documentation is scant).  Or perhaps NPlot
<http://netcontrols.org/nplot/wiki/> has such a beast.  I haven't had a
chance to look into NPlot.  Beyond that you'll probably have to create a
widget;  making a widget on a DrawingArea isn't actually very hard (see
<http://code.google.com/p/consonance/source/browse/trunk/Whitemice.Gtk/Calendar/Whitemice.Gtk.Calendar/DayStrip.cs? for a rough example).

As an aside,  there are some really nice widgets in the Holly Widgets
project <http://code.google.com/p/holly-gtk-widgets/>.  That is
unrelated to your current issue,  but I pitch Holly Widgets every chance
I get.   Gtk# needs more people creating reusable widgets.

Hmm.  That could be an attribute of the theme.  I don't know enough
about themes to say (except that they are often @*^&*&$^*!& frustrating
and it is best to test an app in multiple themes to see that it remains
usable - or even better, don't let users change their theme).
