> Was any suggestion concerning such an extension to ODF ever made?

The ODF TC does not work proactive, but at least one implementation has to
exist.

The current standard has the possibility to store a label of a data point as
fixed text by a <chart:data-label> sub-element of a <chart:data-point> element.
A request to allow a reference to a cell instead of the fixed text is in
https://issues.oasis-open.org/browse/OFFICE-2130

There exists no request to allow a cell-range-address as label source for the
data points of an individual, entire series. The existing
chart:label-cell-address attribute does not contain labels for the data points
but the name of the series itself.

Thus any attempt to implement such feature has to take care, how it can be
saved conform to ODF, and has to make a proposal to the ODF TC.

The workaround still works: Make the data cell range of each series as large as
the common label cell range, but leave data cells empty that do not belong to
the specific series.
For the time being, it might be useful to describe the workaround in the WIKI
and link from the Help to it.
