|

\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>.
