  The use of spreadsheets in industry is widespread. Companies base decisions
on information coming from spreadsheets. Unfortunately, spreadsheets are
error-prone and this increases the risk that companies base their decisions on
inaccurate information, which can lead to incorrect decisions and loss of
money. In general, spreadsheet research is aimed to reduce the error-proneness
of spreadsheets. Most research is concentrated on the use of formulas. However,
there are other constructions in spreadsheets, like charts, pivot tables, and
array formulas, that are also used to present decision support information to
the user. There is almost no research about how these constructions are used.
To improve spreadsheet quality it is important to understand how spreadsheets
are used and to obtain a complete understanding, the use of charts, pivot
tables, and array formulas should be included in research. In this paper, we
analyze two popular spreadsheet corpora: Enron and EUSES on the use of the
aforementioned constructions.
