The chart is created from the selected range, but no range string is shown in
the data range field of the data range tab page. -> Björn, please have a look.

Looking at lcl_detectRanges() I found out that for a range like this:

*   * *
*   * *
*   * *
* * * *

is split up like this:

A    C   D
A    C   D
A    C   D
A B B/C D

I.e., range B consists of two cells which are "in rows", therefore the
splitting-direction (DataRowSource) is ambiguous.

->NN: This only appears for a de-selection where you leave just one cell in a
column like in the example. It is not a very common example, I think. So, I
would only fix this if there is a somewhat obvious fix that does not wreck other
places.

Maybe range B could be detected to be only one cell, and not yield an ambiguous
state in this case, but count as "don't care", because all sub-ranges have "data
in columns" and only one is undecided. This is not really ambiguous (in contrast
to a complete range that only consists of one cell).

Maybe a query like this would solve the situation, once range "B" is only one cell:

                if( !bRowDiff && !bColDiff )
                    ++nUndecided;
                else if( bRowDiff && ! bColDiff )
                    ++nDataInColumns;
                else if( bColDiff && ! bRowDiff )
                    ++nDataInRows;
                else if( bRowDiff && bColDiff )
                    bRowSourceAmbiguous = true;

                if( (nDataInRows > 0 && nDataInColumns) > 0 || nUndecided > 0 )
                    bRowSourceAmbiguous = true;
