+
+Since the chart area is defined by subtracting the space consumed by
+the axes from the printable area there are two options that are
+mutually exclusive.
+
+- Define the chart by precisely specifying (in absolute or in
+relative numbers) how much space may be used by each axis.
+and/or define start and end values for the axes' labels.
+
+-> This produces results that are comparable to each other
+since the chart will have an exactly fixed size and its position
+on the paper will remain the same even if the labels of its axes
+become wider or more narrow.
+Also the graphical representation of the date will be comparable
+since all your charts will use the same scale if you wish this.
+
+- Let the program calculate the chart layout based upon the kind
+of and width of the labels to be drawn at the axes.
+Also the program can calculate the labels for you and find the
+boundary values for start and end of the scale automatically.
+-> This will produce good looking results without you having
+to fiddle around with the settings.
+Unfortunately these charts will not allways be comparable to
+each other if the axes' labels change since both the size of
+the area reserved for the chart and the scaling of the
+scales will vary if the data values do so.
+
+With KDChart both ways are possible, see hints given with
+setAxisAreaMode(), setAxisAreaMin() and setAxisAreaMax().
+
+To optimize your results you might want to use setAxisLineWidth() and
+setAxisLabelsFontPointSize(): negative values will specify it
+in per thousand  of the printable area size - producing a result
+looking fine even if the chart is
+printed at very large dimensions.

+This would specify a default ordinate-axis obtaining its values from the

+chart representing slightly different min/max values since it neither starts
+at zero nor ends at an allways same value.
+
+\verbatim
+setAxisValues( true, KDChartData( 0.0 ) );
+\endverbatim
+This would specify a half-automatical ordinate-axis obtaining its values from
+the attached dataset. Looks nice and can be slightly easier compared to
+another chart since it allways starts at zero, causing negative values to be
+ignored completely.
+
+\verbatim
+setAxisValues( true, KDChartData( -2.0 ),
+        KDChartData(  7.5 ),
+        0.5, 1 );
+\endverbatim
+This would specify an ordinate-axis \not obtaining its values
+from the attached dataset.
+<b>Since both the start value and the end value are specified the range
+of the dataset values are ignored completely.</b>
+It will show one digit behind the comma.
+The resulting chart can be perfectly compared to
+another chart since it allways starts and ends at the very same level - no
+matter what the dataset values are about actually.
+
+\verbatim
+setAxisValues( false, KDChartData( 0.0 ),
+        KDChartData( 3.5),
+        0.25, 2 );
+\endverbatim
+This would specify a default abscissa-axis starting with value 0.0 and
+adding 0.25 to get the next value, will count until 3.5.
+It will show two digits behind the comma.
+
+\verbatim
+setAxisValues( false,
+        KDChartData( 1964.0 ), KDCHART_AXIS_LABELS_AUTO_LIMIT, 1, 0 );
