+ \section1 Selecting a row/column by clicking an axis label
+
+ Selection by axis label is default functionality for bar graphs. As an example, you can select
+ rows by clicking an axis label in the following way:
+
+ \list
+ \li Change selection mode to \c SelectionRow
+ \li Click a year label
+ \li The row with the clicked year is selected
+ \endlist
+
+ You can use the same method with \c SelectionSlice and \c SelectionItem flags, as long as
+ you have either \c SelectionRow or \c SelectionColumn set as well.
