A chart linked to a PivotTable: series are built from the report
(innermost row items x column items/value fields, totals excluded) and
rebuilt on every refresh or layout change; c:pivotSource round trip;
chart series accept union references.

A value field can be a calculated field whose formula is evaluated on
the sums of the fields it names for each report cell (Excel's documented
semantics). Command to add/change/delete, dialog from the field pane,
XLSX cacheField formula round trip.

Each header was checked against every name before it, once per suffix
tried, so a source whose headers repeat (a row of thousands of equal
labels, such as check boxes) took cubic time: 4,000 columns took 28 s
in Recommended PivotTables, and a row of 16,384 hung the app, in
PivotTables, in Insert Table and in Get Data from Table/Range. Taken
names and the next suffix of each header are now kept in hash maps, in
the pivot source, in table creation and in the XLSX pivot cache; the
names are the same as before.
