+ \brief A curve fitter implementing Douglas and Peucker algorithm
+
+ The purpose of the Douglas and Peucker algorithm is that given a 'curve'
+ composed of line segments to find a curve not too dissimilar but that
+ has fewer points. The algorithm defines 'too dissimilar' based on the
+ maximum distance (tolerance) between the original curve and the
+ smoothed curve.
+
+ The runtime of the algorithm increases non linear ( worst case O( n*n ) )
+ and might be very slow for huge polygons. To avoid performance issues
+ it might be useful to split the polygon ( setChunkSize() ) and to run the algorithm
+ for these smaller parts. The disadvantage of having no interpolation
+ at the borders is for most use cases irrelevant.
+
+ The smoothed curve consists of a subset of the points that defined the
+ original curve.
+
+ In opposite to QwtSplineCurveFitter the Douglas and Peucker algorithm reduces
+ the number of points. By adjusting the tolerance parameter according to the
+ axis scales QwtSplineCurveFitter can be used to implement different
+ level of details to speed up painting of curves of many points.

+ For a resolution of 1 ms those start to happen for dates above the
+ year 144683.

+ An axis for a date/time interval is expected to be aligned

+
+ A dial contains a scale and a needle indicating the current value
+ of the dial. Depending on Mode one of them is fixed and the
+ other is rotating. If not isReadOnly() the
+ dial can be rotated by dragging the mouse or using keyboard inputs
+ (see QwtAbstractSlider::keyPressEvent()). A dial might be wrapping, what means
+ a rotation below/above one limit continues on the other limit (f.e compass).
+ The scale might cover any arc of the dial, its values are related to
+ the origin() of the dial.
+
+ Often dials have to be updated very often according to values from external
+ devices. For these high refresh rates QwtDial caches as much as possible.
+ For derived classes it might be necessary to clear these caches manually
+ according to attribute changes using invalidateCache().

+ \brief A paint device for scalable graphics
+
+ QwtGraphic is the representation of a graphic that is tailored for
+ scalability. Like QPicture it will be initialized by QPainter
+ operations and can be replayed later to any target paint device.
+
+ While the usual image representations QImage and QPixmap are not
+ scalable Qt offers two paint devices, that might be candidates
+ for representing a vector graphic:
+
+ - QPicture\n
+ Unfortunately QPicture had been forgotten, when Qt4
+ introduced floating point based render engines. Its API
+ is still on integers, what make it unusable for proper scaling.
+
+ - QSvgRenderer/QSvgGenerator\n
+ Unfortunately QSvgRenderer hides to much information about
+ its nodes in internal APIs, that are necessary for proper
+ layout calculations. Also it is derived from QObject and
+ can't be copied like QImage/QPixmap.
+
+ QwtGraphic maps all scalable drawing primitives to a QPainterPath
+ and stores them together with the painter state changes
+ ( pen, brush, transformation ... ) in a list of QwtPaintCommands.
+ For being a complete QPaintDevice it also stores pixmaps or images,
+ what is somehow against the idea of the class, because these objects
+ can't be scaled without a loss in quality.
+
+ The main issue about scaling a QwtGraphic object are the pens used for
+ drawing the outlines of the painter paths. While non cosmetic pens
+ ( QPen::isCosmetic() ) are scaled with the same ratio as the path,
+ cosmetic pens have a fixed width. A graphic might have paths with
+ different pens - cosmetic and non-cosmetic.
+
+ QwtGraphic caches 2 different rectangles:
+
+ - control point rectangle\n
+ The control point rectangle is the bounding rectangle of all
+ control point rectangles of the painter paths, or the target
+ rectangle of the pixmaps/images.
+
+ - bounding rectangle\n
+ The bounding rectangle extends the control point rectangle by
+ what is needed for rendering the outline with an unscaled pen.
+
+ Because the offset for drawing the outline depends on the shape
+ of the painter path ( the peak of a triangle is different than the flat side )
+ scaling with a fixed aspect ratio always needs to be calculated from the
+ control point rectangle.

+/*!
+ \brief QwtPicker provides selections on a widget
+
+ QwtPicker filters all enter, leave, mouse and keyboard events of a widget
+ and translates them into an array of selected points.
+
+ The way how the points are collected depends on type of state machine
+ that is connected to the picker. Qwt offers a couple of predefined
+ state machines for selecting:
+
+ - Nothing\n
+ QwtPickerTrackerMachine
+ - Single points\n
+ QwtPickerClickPointMachine, QwtPickerDragPointMachine
+ - Rectangles\n
+ QwtPickerClickRectMachine, QwtPickerDragRectMachine
+ - Polygons\n
+ QwtPickerPolygonMachine
+
+ While these state machines cover the most common ways to collect points
+ it is also possible to implement individual machines as well.
+
+ QwtPicker translates the picked points into a selection using the
+ adjustedPoints() method. adjustedPoints() is intended to be reimplemented
+ to fix up the selection according to application specific requirements.
+ (F.e. when an application accepts rectangles of a fixed aspect ratio only.)
+
+ Optionally QwtPicker support the process of collecting points by a
+ rubber band and tracker displaying a text for the current mouse
+ position.
+
+ \par Example
+ \verbatim #include <qwt_picker.h>
+#include <qwt_picker_machine.h>
+
+QwtPicker *picker = new QwtPicker(widget);
+picker->setStateMachine(new QwtPickerDragRectMachine);
+picker->setTrackerMode(QwtPicker::ActiveOnly);
+picker->setRubberBand(QwtPicker::RectRubberBand); \endverbatim\n
+
+ The state machine triggers the following commands:
+
+ - begin()\n
+ Activate/Initialize the selection.
+ - append()\n
+ Add a new point
+ - move() \n
+ Change the position of the last point.
+ - remove()\n
+ Remove the last point.
+ - end()\n
+ Terminate the selection and call accept to validate the picked points.
+
+ The picker is active (isActive()), between begin() and end().
+ In active state the rubber band is displayed, and the tracker is visible
+ in case of trackerMode is ActiveOnly or AlwaysOn.
+
+ The cursor can be moved using the arrow keys. All selections can be aborted
+ using the abort key. (QwtEventPattern::KeyPatternCode)
+
+ \warning In case of QWidget::NoFocus the focus policy of the observed
+ widget is set to QWidget::WheelFocus and mouse tracking
+ will be manipulated while the picker is active,
+ or if trackerMode() is AlwayOn.

+ \brief A 2-D plotting widget
+
+ QwtPlot is a widget for plotting two-dimensional graphs.
+ An unlimited number of plot items can be displayed on
+ its canvas. Plot items might be curves (QwtPlotCurve), markers
+ (QwtPlotMarker), the grid (QwtPlotGrid), or anything else derived
+ from QwtPlotItem.
+ A plot can have up to four axes, with each plot item attached to an x- and
+ a y axis. The scales at the axes can be explicitly set (QwtScaleDiv), or
+ are calculated from the plot items, using algorithms (QwtScaleEngine) which
+ can be configured separately for each axis.
+
+ The simpleplot example is a good starting point to see how to set up a
+ plot widget.
+
+ \image html plot.png
+
+ \par Example
+ The following example shows (schematically) the most simple
+ way to use QwtPlot. By default, only the left and bottom axes are
+ visible and their scales are computed automatically.
+ \verbatim
+#include <qwt_plot.h>
+#include <qwt_plot_curve.h>
+
+QwtPlot *myPlot = new QwtPlot("Two Curves", parent);
+
+// add curves
+QwtPlotCurve *curve1 = new QwtPlotCurve("Curve 1");
+QwtPlotCurve *curve2 = new QwtPlotCurve("Curve 2");
+
+// connect or copy the data to the curves
+curve1->setData(...);
+curve2->setData(...);
+
+curve1->attach(myPlot);
+curve2->attach(myPlot);

+ <dl><dt>a) Assign curve properties</dt>
+ <dd>When a curve is created, it is configured to draw black solid lines

+
+ A plot item is "something", that can be painted on the plot canvas,
+ or only affects the scales of the plot widget. They can be categorized as:
+
+ - Representator\n
+ A "Representator" is an item that represents some sort of data
+ on the plot canvas. The different representator classes are organized
+ according to the characteristics of the data:
+ - QwtPlotMarker
+ Represents a point or a horizontal/vertical coordinate
+ - QwtPlotCurve
+ Represents a series of points
+ - QwtPlotSpectrogram ( QwtPlotRasterItem )
+ Represents raster data
+ - ...
+
+ - Decorators\n
+ A "Decorator" is an item, that displays additional information, that
+ is not related to any data:
+ - QwtPlotGrid
+ - QwtPlotScaleItem
+ - QwtPlotSvgItem
+ - ...
+
+ Depending on the QwtPlotItem::ItemAttribute flags, an item is included
+ into autoscaling or has an entry on the legend.
+
+ Before misusing the existing item classes it might be better to
+ implement a new type of plot item
+ ( don't implement a watermark as spectrogram ).
+ Deriving a new type of QwtPlotItem primarily means to implement
+ the YourPlotItem::draw() method.

+ \brief QwtPlotZoomer provides stacked zooming for a plot widget
+
+ QwtPlotZoomer selects rectangles from user inputs ( mouse or keyboard )
+ translates them into plot coordinates and adjusts the axes to them.
+ The selection is supported by a rubber band and optionally by displaying
+ the coordinates of the current mouse position.
+
+ Zooming can be repeated as often as possible, limited only by
+ maxStackDepth() or minZoomSize(). Each rectangle is pushed on a stack.
+
+ The default setting how to select rectangles is
+ a QwtPickerDragRectMachine with the following bindings:
+
+ - QwtEventPattern::MouseSelect1\n
+ The first point of the zoom rectangle is selected by a mouse press,
+ the second point from the position, where the mouse is released.
+
+ - QwtEventPattern::KeySelect1\n
+ The first key press selects the first, the second key press
+ selects the second point.
+
+ - QwtEventPattern::KeyAbort\n
+ Discard the selection in the state, where the first point
+ is selected.
+
+ To traverse the zoom stack the following bindings are used:
+
+ - QwtEventPattern::MouseSelect3, QwtEventPattern::KeyUndo\n
+ Zoom out one position on the zoom stack
+
+ - QwtEventPattern::MouseSelect6, QwtEventPattern::KeyRedo\n
+ Zoom in one position on the zoom stack
+
+ - QwtEventPattern::MouseSelect2, QwtEventPattern::KeyHome\n
+ Zoom to the zoom base
+
+ The setKeyPattern() and setMousePattern() functions can be used
+ to configure the zoomer actions. The following example
+ shows, how to configure the 'I' and 'O' keys for zooming in and out
+ one position on the zoom stack. The "Home" key is used to
+ "unzoom" the plot.
+
+ \code
+ zoomer = new QwtPlotZoomer( plot );
+ zoomer->setKeyPattern( QwtEventPattern::KeyRedo, Qt::Key_I, Qt::ShiftModifier );
+ zoomer->setKeyPattern( QwtEventPattern::KeyUndo, Qt::Key_O, Qt::ShiftModifier );
+ zoomer->setKeyPattern( QwtEventPattern::KeyHome, Qt::Key_Home );
+ \endcode
+
+ QwtPlotZoomer is tailored for plots with one x and y axis, but it is
+ allowed to attach a second QwtPlotZoomer ( without rubber band and tracker )
+ for the other axes.
+
+ \note The realtime example includes an derived zoomer class that adds
+ scrollbars to the plot canvas.

+
+ A subclass of QwtSeriesData<QPointF> must implement:
+
+ - size()\n
+ Should return number of data points.
+
+ - sample()\n
+ Should return values x and y values of the sample at specific position
+ as QPointF object.
+
+ - boundingRect()\n
+ Should return the bounding rectangle of the data series.
+ It is used for autoscaling and might help certain algorithms for displaying
+ the data. You can use qwtBoundingRect() for an implementation
+ but often it is possible to implement a more efficient algorithm
+ depending on the characteristics of the series.
+ The member d_boundingRect is intended for caching the calculated rectangle.

+ \brief A class for spline interpolation
+
+ The QwtSpline class is used for cubical spline interpolation.
+ Two types of splines, natural and periodic, are supported.
+
+ \par Usage:
+ <ol>
+ <li>First call setPoints() to determine the spline coefficients
+ for a tabulated function y(x).
+ <li>After the coefficients have been set up, the interpolated
+ function value for an argument x can be determined by calling
+ QwtSpline::value().
+ </ol>
+
+ \par Example:
+ \code
+#include <qwt_spline.h>
+
+QPolygonF interpolate(const QPolygonF& points, int numValues)
+{
+ QwtSpline spline;
+ if ( !spline.setPoints(points) )
+ return points;
+
+ QPolygonF interpolatedPoints(numValues);
+
+ const double delta =
+ (points[numPoints - 1].x() - points[0].x()) / (points.size() - 1);
+ for(i = 0; i < points.size(); i++) / interpolate
+ {
+ const double x = points[0].x() + i * delta;
+ interpolatedPoints[i].setX(x);
+ interpolatedPoints[i].setY(spline.value(x));
+ }
+ return interpolatedPoints;
