Areas of the chart that may have their own backgrounds
and/or may be surrounded by a simple or complex border.
\li \c AreaData surrounding the data area
\li \c AreaAxes surrounding the axes but leaving out the data area
\li \c AreaDataAxes surrounding the data+axes area
\li \c AreaLegend surrounding the legend area
\li \c AreaDataAxesLegend surrounding the data+axes+legend area
\li \c AreaHeaders surrounding the headers area
\li \c AreaFooters surrounding the footers area
\li \c AreaDataAxesLegendHeadersFooters surrounding the data+axes+legend+headers+footers area
\li \c AreaInnermost covering the complete drawing area but <b>not</b> covering the global left/top/right/bottom leading
\li \c AreaOutermost covering the complete drawing area including the global left/top/right/bottom leading
\li \c AreaChartDataRegion covering the area used to display one data entry (i.e. one point, bar, line, pie slice,...).
The respective data coordinates are specified by additional parameters, this is used by
KDChartCustomBox where you have the parameters \c dataRow, \c dataCol, \c data3rd.
In addition there is a special value specifying a <b>list</b> of regions:
\li \c AreasCustomBoxes specifies many small areas surrounding all the custom boxes that you might have added to the chart,
this is useful in case you want to specify some default frame settings to be used for all custom boxes
not having frame settings of their own.
Finally there are three special values that you may use to specify
a single axis area (or a header/footer area, or a custom box area resp.).
Just add the number of the axis (or header/footer, or custom box resp.)
to the respective base value:
\li \c AreaAxisBASE value to be added to the axis number in case you want to specify a single axis area,
e.g. for specifying the area of the left ordinate axis just type <b>AreaAxisBASE + AxisPosLeft</b>.
\li \c AreaHdFtBASE value to be added to the header/footer number in case you want to specify a single header (or footer, resp.) area,
e.g. for specifying the area of the main header just type <b>AreaHdFtBASE + HdFtPosHeader</b>.
\li \c AreaCustomBoxBASE value to be added to the number of a custom box that you might have added to your chart,
e.g. for specifying the area a custom box you have added to the chart
(let us assume the index of that box is in \c boxIdx1) just type <b>AreaCustBoxBASE + boxIdx1</b>.

The general position flag to specify a point of
an area, for example this could be the anchor point
which an annotation box should be aligned to.

\note The position and tqalignment of content to be printed at (or
inside of, resp.) an area or a point -- like for printing data value texts next
to their graphical representations (which might be a bar, line, pie slice,...) --
is specified by two parameters: a \c PositionFlag and a uint holding a combination of \c TQt::AlignmentFlags.
Remember that TQt::AlignmentFlags are used to specify <b>with which edge</b> something
is to be aligned to its anchor, e.g. \c AlignLeft means align with the left edge.
The position of content and the way it is aligned to this
position is shown in the following drawing, note that annotation #2 and annotation #3
share the same PositionFlag but have different tqalignment flags set:
