that is because the page is using _collections_. there are two
collections on the page: the default collection of nobelists+disciplines
and the "disciplines" collection of disciplines. the bar chart is using
the disciplines collection via the "collectionID" attribute; the facets
are filtering the default collection (and in fact, are only relevant to
the nobelists).
I think what you would like to do is filter the nobelists, then use the
bar chart to plot how many nobelists are selected in each discipline.
Unfortunately this is not currently possible. The bar chart is designed
to take a collection of items, to make a row for each item, and to
compute a value for each item. the way i have it set up, the values are
the disciplines and the value is the number of nobelists with that
discipline. This is done using the count(!discipline) function.
Unfortunately there is no way in the exhibit function language to
specify that you want the number of nobelists _currently filtered_ that
have the given discipline.

Thanks Karger,
This is certainly how I want it to look. But I cannot comprehend why
the bar chart is not tied to the facets, that it doesn't change when
the selections in the facet change.
This is a wonderful library and I thoroughly enjoyed using it so far.
Hearty thanks to all those involved in this so far!

Hi,
I would like to generate a Bar chart (or even a tabular view to start
with) to list each property against its count (basically similar to
the information displayed on facets). To explain using the "Nobel
list" example from tutorial:
"I need to create a bar chart showing number of Nobel prize winners
from each discipline (or grouped by any of the properties for that
matter)"
Is it possible to achieve that without populating the json with the
necessary meta data (i.e, count the Nobel winners per discipline and
feeding it in to the json). Please excuse if this is a n00b question,
I really did try my best to find it out from existing scattered
documentation.
