Hi Steve,
Assuming I read it right, there's a couple of options.
1) Do it manually. Expose _DEP_histogram{0}.count and then in an
AttributeCreator create an attribute called OnTime using the exposed
attribute to set the value.
2) Automatically. Use Jeff Konnen's excellent idea for the
FMEFunctionCaller - I just tried this with a workspace using the syntax...
@CopyAttributes(@Value(histogramList{0}.value),histogramList{0}.count)
...and it worked fine.
The only problem is that the attribute isn't 'exposed' within
Workbench. You'd have to expose it manually.
I will post my workspace to fmepedia shortly as an example of how to
use FMEFunctionCaller (and ListHistogrammer). In fact I might even
roll it into a custom transformer, because then you could loop through
the list creating an attribute for each entry.
With development for FME2008 due to start I'm sure we (the support
team) will be asked what our hot issues are for this year. I think I
will suggest a transformer to create an attribute, taking the
attribute name from an existing attribute value. It seems to be a
popular need.
If you have FME suggestions then don't forget the add them the list on
fmepedia... http://www.fmepedia.com/index.php/FME_Suggestions (we do
look at this, promise).

Mark
