/**

  Returns the parameter \c d rounded to the nearest integer.

/**
  Specifies if and how a chart will print the data value texts near
  their respective entries.

  Data value texts will be printed immediately after drawing all of
  the chart data points (or bars, lines,...) but before drawing the
  legend and before drawing any custom boxes.  If more than one chart
  ist to be drawn (sharing the same data area) printing of the data
  text values will take place after drawing all of the last charts
  data points, this enables us to see the texts even if their
  respective data representations are covered by the second charts
  drawings. The same covering/colliding problem might occur with Area
  charts if one area is (partially) covering another area.  In such
  cases you might either want to specify an appropriate
  TextLayoutPolicy for getting a better looking result or specify an
  other text color for data value texts of the second chart since by
  default the first chart has black texts while the second chart
  shows its data value texts in dark blue color.

  \note Only used if chartType() is <b>neither HiLo nor
  BoxWhisker</b>. To specify printing of data values in a HiLo chart
  please use setHiLoChartPrintLowValues, setHiLoChartPrintHighValues,
  setHiLoChartPrintOpenValues, setHiLoChartPrintCloseValues. To
  specify printing of data values in a BoxWhisker chart please use
  setBWChartPrintStatistics.

  Calling <b>setPrintDataValues( false )</b> will <b>deactivate</b>
  printing of the values.

  Calling setPrintDataValuesWithDefaultFontParams( chart ) will
  <b>reset</b> the respective font size and colour and position
  parameters (but not the QFont itself) and <b>activate</b> printing
  of the values for the \c chart speficied (or for all charts by
  using \c KDChartParams::KDCHART_ALL_CHARTS, resp.).

  \param active specifies whether the value texts are to be printed or not.
  \param chart The number of the chart: 0 for the first chart, 1 for
  the second chart in case there are two charts to be drawn sharing the
  same data area.  Use the special value KDChartParams::KDCHART_ALL_CHARTS
  to specify that your settings are to be taken for both charts.
  \param divPow10 The power of 10 which the data value is to be divided by.
  A value of 2 means divide by 100, a value of  -3 means multiply by 1000,
  and 0 (by definition) would result in multiplying by 1.
  \param digitsBehindComma The number of digits to show behind the comma,
  to have this calculated automatically just use the default value
  KDChartParams::DATA_VALUE_AUTO_DIGITS.
  \param font a Pointer to the font to be used, if zero the default data value
  texts font will be taken (this is a Times font since small Times digits are
  clearer than small Helvetica digits).

  Changing of one or more of <b>the following parameters</b>
  automatically de-activates all future font parameter adjustments
  that would otherwise take place after each call of setChartType (or
  setAdditionalChartType, resp.).  To re-enable this usefull feature
  you may call setPrintDataValuesWithDefaultFontParams at any time
  afterwards.

  \param size (in per mille of the chart width) the dynamic size of
  the font to be used. If this parameter is zero the size of the
  \c font is used instead - regardless of the size of the chart!
  You may use setPrintDataValuesFontRelSize to change this parameter setting
  without affecting the other ones.
  \param color the color to be used when printing the values.
  To have the color calculated automatically - useful when printing
  inside the bars (or pie slices, areas, ... resp.) - please use
  \c DATA_VALUE_AUTO_COLOR instead of a QColor*.
  You may use setPrintDataValuesColor to change this parameter setting
  without affecting the other ones.

  The following parameters apply to values less than zero only:

  \param negativePosition The anchor position which the text is to be
aligned to.
\param negativeAlign The way how the text is to be aligned to the anchor.
This must be a reasonable combination of Qt::AlignmentFlags.
\param negativeDeltaX The X distance between the <b>anchor
point</b> -- specified by \c negativePosition (or \c
        positivePosition, resp.) -- and the internal <b>alignment point</b>
of the text -- specified by \c negativeAlign (or \c positiveAlign,
        resp.). <b>Note: </b> For better compatibility to the dynamic font
size this parameter is interpreted as being a per-cent value of the
used font height.  If greater 0, the X position is increased, if
less than 0, it is reduced. Actual font size and thus also this
delta value are calculated dynamically before painting based on the
size of the chart and the specification made via parameter \c size.

\param negativeDeltaY The Y distance between the <b>anchor
point</b> -- specified by \c negativePosition (or \c
        positivePosition, resp.) -- and the internal <b>alignment point</b>
of the text -- specified by \c negativeAlign (or \c positiveAlign,
        resp.).  <b>Note: </b> For better compatibility to the dynamic font
size this parameter is interpreted as being a per-cent value of the
used font height.  If greater 0, the Y position is increased, if
less than 0, it is reduced. Actual font size and thus also this
delta value are calculated dynamically before painting based on the
size of the chart and the specification made via parameter \c size.
\param negativeRotation The amount of degrees (using a circle of
        360 degrees) taken to rotate the text. Positive values rotate
clockwise, negative values rotate counter-clockwise.  There are two
special values that you might find usefull for Pie charts or for
Ring charts: \c KDChartParams::SAGGITAL_ROTATION and \c
KDChartParams::TANGENTIAL_ROTATION both leading to individual
calculation of appropriate rotation for each data value.  Rotation
will be performed around the internal <b>alignment point</b> of the
text -- specified by \c negativeAlign (or \c positiveAlign, resp.).

The following parameters apply to values greater than zero or equal zero:

\param positivePosition The anchor position which the text is to be
aligned to.
\param positiveAlign The way how the text is to be aligned to the anchor.
This must be a reasonable combination of Qt::AlignmentFlags.
\param negativeDeltaX The X distance between the <b>anchor
point</b> -- specified by \c negativePosition (or \c
        positivePosition, resp.) -- and the internal <b>alignment point</b>
of the text -- specified by \c negativeAlign (or \c positiveAlign,
        resp.).  <b>Note: </b> For better compatibility to the dynamic font
size this parameter is interpreted as being a per-cent value of the
used font height.  If greater 0, the X position is increased, if
less than 0, it is reduced. Actual font size and thus also this
delta value are calculated dynamically before painting based on the
size of the chart and the specification made via parameter \c size.
\param positiveDeltaY The Y distance between the <b>anchor
point</b> -- specified by \c negativePosition (or \c
        positivePosition, resp.) -- and the internal <b>alignment point</b>
of the text -- specified by \c negativeAlign (or \c positiveAlign,
        resp.).  <b>Note: </b> For better compatibility to the dynamic font

less than 0, it is reduced. Actual font size and thus also this
delta value are calculated dynamically before painting based on the
size of the chart and the specification made via parameter \c size.

        360 degrees) taken to rotate the text. Positive values rotate
clockwise, negative values rotate counter-clockwise.  There are two

calculation of appropriate rotation for each data value.  Rotation
will be performed around the internal <b>alignment point</b> of the
text -- specified by \c negativeAlign (or \c positiveAlign, resp.).

\param layoutPolicy The way to handle too narrow space conflicts:
what to do if a data text covers a neighboring data text (or a
        neighboring data area, resp.).

/**
  \enum KDChartParams::SourceMode

  The chart source mode.
  Use \c setChartSourceMode to specify if and how any data
  should be taken into account for a given chart.

  \sa setChartSourceMode, chartSourceMode, setAdditionalChartType
  */


/**
  Specifies the chart source mode of one or more datasets.
  Use this to specify if and how any data should be taken
  into account for a given chart. You may call this function
  multiple times to specify how the different datasets are to
  be used. Number of datasets is only limited by the data that
  you actually provide to the chart widget. Usage of this method
  is mandatory when specifying combinations of more than one
  chart (e.g. via \c setAdditionalChartType() ).

  \note If specifying <b>more than one dataset</b> for the very
  same chart and the same source mode make sure they form
  a contiguous <b>series</b>.<br>
  It is not possible to use dataset 0..3 as DataEntry, dataset
  4 as AxisLabel and again dataset 5..6 as DataEntry for the
  very same chart!<br>
  Of course you could specify 0..3 as DataEntry for chart 0
  while 5..6 would contain the data entries for chart 1
  when specifying a widget showing two charts.

  <b>Also note:</b><br>
  Whenever you use \c setChartSourceMode() make sure not to
  forget any of the datasets which you want to define: not
  specifying a dataset would result in it being ignored.<br>
  So the rule is: either don't call setChartSourceMode() at all
  or call it for each dataset!

  To quickly clear all such settings just might want to call
  <b>setChartSourceMode( UnknownMode, KDCHART_ALL_DATASETS );</b>
  without specifying a dataset number and without specifying
  a chart number.<br>
  However this KDCHART_ALL_DATASETS may only be used to
  <b>clear</b> SourceMode settings - but not for defining the
  SourceMode for all datasets - the above mentioned combination
  with <b>UnknownMode</b> is the only way how to use
  <b>KDCHART_ALL_DATASETS</b> here!

  <b>Examples:</b>

  \verbatim
  setChartSourceMode( DataEntry, 2 );
  \endverbatim
  This would specify a simple chart obtaining its values from dataset 2.

  \verbatim
  setChartSourceMode( DataEntry, 0, 0, 0 );
  setChartSourceMode( DataEntry, 3, 3, 1 );
  \endverbatim
  This would specify a two chart widget - the 1st obtaining its values
  from dataset 0 and the 2nd taking the values from dataset 3.

  \verbatim
  setChartSourceMode( LegendText,       1,  1, 0 );
  setChartSourceMode( AxisLabel,        2,  2, 0 );
  setChartSourceMode( DataEntry,        3,  6, 0 );
  setChartSourceMode( ExtraLinesAnchor, 7,  7, 0 );
  setChartSourceMode( LegendText,       8,  8, 1 );
  setChartSourceMode( AxisLabel,        9,  9, 1 );
  setChartSourceMode( DataEntry,       10, 13, 1 );
  \endverbatim
  This would specify a two chart widget - the 1st obtaining its values
  from datasets 3..6 and the 2nd taking the values from datasets 10..13.
  Their respective legends and axes would take their values from
  datasets 1 and 2 (or 8 and 9, resp.).
  Additionally the 1st chart would use dataset 7 to determine the
  horizontal (or vertical, resp.) position of any extra lines
  that might be specified by KDChartPropertySet IDs assigned to
  the cells in dataset 7.

  \note If source mode is ExtraLinesAnchor all cells
  of the respective datset will be ignored when the normal
  cell representations (e.g. Bars or Lines) are drawn - these
  cells will <em>only</em> be used as anchor points for any
  extra lines that are specified with these cell's property sets.

  When specifying \c ExtraLinesAnchor for more than one dataset
  of the same chart make sure they form a contiguous row
  <b>together</b> with the \c DataEntry dataset(s): e.g
  you may use datasets 3..8 for DataEntry cells and datasets
  9..10 for ExtraLinesAnchor cells.
  All datasets with mode DataEntry or ExtraLinesAnchor are taken
  into account for calculation of the axes ranges and delimiters.

  <P>

  \param mode the way how to use information stored in this dataset.
  \param dataset the dataset number to be used (or ignored, resp.).
  Use \c KDCHART_ALL_DATASETS to indicate that information given
  applies to all of the datasets.
  \param dataset2 a second dataset number to be taken into account
  (or ignored, resp.). Use this one together with the \dataset

/**
  Specifies the additional chart type.
  The default is no additional chart (NoType).
  The additional chart will have <b>no grid</b> so either make sure you
  specify the chart that should have a grid via \c setChartType() and
  the other one as additional chart or specify the grid manually if you
  need one for the additional chart too.

  The additional chart uses the same abscissa axis as the main chart,
  but cannot change the abscissa settings: the abscissa range and step width
  is determined according to the main chart's values.

  You may combine all different types of cartesian charts
  (== Bar, Line, HiLo, ..., but not Polar, Pie, ...)
  so e.g. the following combinations are possible:<br>

  \verbatim
  setChartType( KDChartParams::Bar );
  setAdditionalChartType( KDChartParams::Line );
  \endverbatim
  or
  \verbatim
  setChartType( KDChartParams::Line );
  setAdditionalChartType( KDChartParams::HiLo );
  \endverbatim
  or
  \verbatim
  setChartType( KDChartParams::Bar );
  setAdditionalChartType( KDChartParams::Bar );
  ...
  \endverbatim

  \note When defining multiple charts it is mandatory to
  call \c setChartSourceMode() for specifying the dataset(s)
  and their respective charts after calling \c setAdditionalChartType(),
  also it is recommended to call \c setAxisDatasets() for all
  axes to be used by the different datasets - otherwise the
  default setting will be used (all datasets except the last
  one match the left axis, the last dataset matches the right axis),
  so e.g. your code to have a bar chart for datasets 0..2 (using the
  left axis) and a line chart for datasets 3..4 (using the right axis)
  could look like this:

  \verbatim
  setChartType( KDChartParams::Bar );
  setAdditionalChartType( KDChartParams::Line );
  setChartSourceMode( KDChartParams::DataEntry,     0,2, 0 );
  setChartSourceMode( KDChartParams::DataEntry,     3,4, 1 );
  setAxisDatasets( KDChartAxisParams::AxisPosLeft,  0,2, 0 );
  setAxisDatasets( KDChartAxisParams::AxisPosRight, 3,4, 1 );
  \endverbatim

  \note In case you DON'T want to use the right axis but the left axis #2
  make sure to reset the dataset assignment that is automatically done for
  the right axis. Doing this will also clear the visibility flag of the
  right axis that is automatically set by setAdditionalChartType()
  implicitely assuming that the additional chart will use the right axis,
  so there is no need to explicitely call setAxisVisible( false ) for
  the right axis: specifying KDCHART_NO_DATASET is enough to disable it.
  e.g. in the example shown above you would replace the
  last line by these ones:

  \verbatim
  setAxisDatasets( KDChartAxisParams::AxisPosLeft2, 3,4, 1 );
  setAxisDatasets( KDChartAxisParams::AxisPosRight,
  KDChartParams::KDCHART_NO_DATASET );
  \endverbatim

  Often your additional chart will look better when not overlapping with
  the first chart, specifying different y-positions for the charts
  is possible by \c KDChartAxisParams::setAxisUseAvailableSpace(),
  e.g. like this:

\verbatim
// specify which amount of the available space
// is to be used by the first y-axis:

KDChartAxisParams pa(
        _p->axisParams( KDChartAxisParams::AxisPosLeft ) );
pa.setAxisUseAvailableSpace( 0, -499 );
_p->setAxisParams( KDChartAxisParams::AxisPosLeft, pa );

// specify which amount of the available space
// is to be used by the second y-axis:

pa = _p->axisParams( KDChartAxisParams::AxisPosLeft2 );
pa.setAxisUseAvailableSpace( -750, -1000 );
_p->setAxisParams( KDChartAxisParams::AxisPosLeft2, pa );
\endverbatim

  \fn void KDChartParams::setExplode( bool explode )

  Specifies whether the pie chart or ring chart should be
  exploding (all pies or ring segments are slightly displaced
  from the center) or not. The default is not to explode. Only
  used if chartType() == Pie or chartType() == Ring.

  Note that calling this method by passing true turns on
  exploding for all segments. You can turn exploding on and off
  for individual segments by calling setExplodeValues() and also
  change the explode factors by calling setExplodeFactor() or
  setExplodeFactors().

  Note that in ring charts, only the outermost ring is
  exploded. Also note that exploding rings are only useful if
  none of the values in the outermost dataset covers more than
  1/4 of the ring, otherwise the exploded ring will look funny.

  Specifies which values to explode. Explosion of values only
  happens if setExplode( true ) has been called. Normally, all
  values are exploded (all values on the outer ring in the case of a
  ring chart). With this function, you have a finer control about
  the explosion. You can specify the values that should be exploded
  by their position. Passing an empty list here turns on explosion
  for all pies or ring segments (but only if explosion is turned on
  in general).

  To repeat: Setting anything here has no effect if setExplode( true )
  is not called. You can, however, set any values here even if explosion is
  not turned on; they will be saved in case explosion will be turned on in
  the future and then be valid automatically.

  The explode factor, i.e., the amount with which a segment is moved
  from the center can either be set for all segments with
  \a setExplodeFactor() or for individual segments with
  \a setExplodeFactors(). The default is 10%.

  i.e. how much an exploded pie or ring segment is displaced from
  the center. The factor is given as a double value between 0 and 1;
  0.1 means 10%. Only used if chartType() == Pie or chartType() ==
  Ring and explode() == true.

  Segments that are not contained in the map specified here will
  have the default explode factor of 10%, if exploding is turned on
  for them at all. This also means that passing an empty list to
  this method does not turn off exploding in general; use \a
  setExplode( false ) for that.

Note: This method has no immediate effect if setExplode( true )
has not been called. It is, however, possible to preset explode
factors and then turn on exploding later.

Note: Besides giving a segment an explode factor and turning on
exploding in general, you also need to specify to explode a
certain segment by calling \a setExplodeValues(). This gives maximum
flexibility as it allows you to preset explode factors and then
explode or not not explode a segment at leisure - at the expense
of one more method call.

  You may use up to 9 header and/or up to 9 footer sections.

  \li Up to three <b>leading headers</b> ( \c HdFtPosHeader0 , \c
  HdFtPosHeader0L , \c HdFtPosHeader0R ) may be drawn at the very upper
  edge of the printable area. <br>
  You might want to use those sections to show some marginal information
  like department name, print date, page number... <br>
  <b>Note:</b> Those headers <b>share the same area</b> so make sure to
  specify propper horizontal alignment for each section when using more than
  one of them. By default \c HdFtPosHeader0 has centered alignement,
  \c HdFtPosHeader0L is aligned to the left and \c HdFtPosHeader0R to the
  right side. All of them are vertically aligned to the bottom, you may
  change this at your own risk: the resulting output might look strange. <br>
  <b>also note:</b> Alignment to bottom here means their baselines are
  horizontally adjusted to each other when more than one of them is used - it
  does <b>not</b> mean the <b>lowest pixel positions</b> of their output will
  be at the very same y coordinate since those might vary depending from the
  font size and or the font size you have specified for each of the sections.

  \li Up to three <b>main headers</b> ( \c HdFtPosHeader , \c
  HdFtPosHeaderL , \c HdFtPosHeaderR ) may be drawn under the
  leading header(s). <br>
  You could use this headers to show the main information such as project name,
  chart title or period of time (e.g. census year). <br>
  Like their counterparts they share the same part of the printable area so the
  restrictions regarding alignment mentioned above apply also to these three
  sections.

  \li Up to three <b>additional headers</b> ( \c HdFtPosHeader2 , \c
  HdFtPosHeader2L , \c HdFtPosHeader2R ) may be drawn under the main
  header(s). <br>
  This headers could show additional information such as project phase, chart
  sub-title or sub-period of time (e.g. census quarter-year). <br>
  Like their counterparts they share the same part of the printable area so the
  restrictions regarding alignment mentioned above apply also to these three
  sections.

  <p>

  \li Up to three <b>main footers</b> ( \c HdFtPosFooter , \c
  HdFtPosFooterL , \c HdFtPosFooterR ) may be drawn under the chart data
  area (or the legend that might be shown below that area, resp.). <br>
  You might want to use these footers instead of (or additional to) the
  main header(s) for showing the main information... <br>
  Like their header-counterparts they share the same part of the printable area
  so the restrictions regarding alignment mentioned above apply also to these
  three sections.

  \li Up to three <b>additional footers</b> ( \c HdFtPosFooter2 , \c
  HdFtPosFooter2L , \c HdFtPosHeader2R ) may be drawn under the main
  footer(s). <br>
  This footers could show additional information instead of (or additional to)
  the additional header(s). <br>
  Like their counterparts they share the same part of the printable area so the
  restrictions regarding alignment mentioned above apply also to these three
  sections.

  \li Up to three <b>trailing footers</b> ( \c HdFtPosFooter0 , \c
  HdFtPosFooter0L , \c HdFtPosFooter0R ) may be drawn at the very lower
  edge of the printable area: <b>under</b> the other footer sections <br>
  You might want to use those sections to show some marginal information
  instead of (or additional to) the leading header(s). <br>
  Like their counterparts they share the same part of the printable area so the
  restrictions regarding alignment mentioned above apply also to these three
