/*! \class QCPDataContainer
  \brief The generic data container for one-dimensional plottables
 
  This class template provides a fast container for data storage of one-dimensional data. The data
  type is specified as template parameter (called \a DataType in the following) and must provide
  some methods as described in the \ref qcpdatacontainer-datatype "next section".
 
  The data is stored in a sorted fashion, which allows very quick lookups by the sorted key as well
  as retrieval of ranges (see \ref findBegin, \ref findEnd, \ref keyRange) using binary search. The
  container uses a preallocation and a postallocation scheme, such that appending and prepending
  data (with respect to the sort key) is very fast and minimizes reallocations. If data is added
  which needs to be inserted between existing keys, the merge usually can be done quickly too,
  using the fact that existing data is always sorted. The user can further improve performance by
  specifying that added data is already itself sorted by key, if he can guarantee that this is the
  case (see for example \ref add(const QVector<DataType> &data, bool alreadySorted)).
 
  The data can be accessed with the provided const iterators (\ref constBegin, \ref constEnd). If
  it is necessary to alter existing data in-place, the non-const iterators can be used (\ref begin,
  \ref end). Changing data members that are not the sort key (for most data types called \a key) is
  safe from the container's perspective.
 
  Great care must be taken however if the sort key is modified through the non-const iterators. For
  performance reasons, the iterators don't automatically cause a re-sorting upon their
  manipulation. It is thus the responsibility of the user to leave the container in a sorted state
  when finished with the data manipulation, before calling any other methods on the container. A
  complete re-sort (e.g. after finishing all sort key manipulation) can be done by calling \ref
  sort. Failing to do so can not be detected by the container efficiently and will cause both
  rendering artifacts and potential data loss.
 
  Implementing one-dimensional plottables that make use of a \ref QCPDataContainer<T> is usually
  done by subclassing from \ref QCPAbstractPlottable1D "QCPAbstractPlottable1D<T>", which
  introduces an according \a mDataContainer member and some convenience methods.
 
  \section qcpdatacontainer-datatype Requirements for the DataType template parameter
 
  The template parameter <tt>DataType</tt> is the type of the stored data points. It must be
  trivially copyable and have the following public methods, preferably inline:
 
  \li <tt>double sortKey() const</tt>\n Returns the member variable of this data point that is the
  sort key, defining the ordering in the container. Often this variable is simply called \a key.
 
  \li <tt>static DataType fromSortKey(double sortKey)</tt>\n Returns a new instance of the data
  type initialized with its sort key set to \a sortKey.
 
  \li <tt>static bool sortKeyIsMainKey()</tt>\n Returns true if the sort key is equal to the main
  key (see method \c mainKey below). For most plottables this is the case. It is not the case for
  example for \ref QCPCurve, which uses \a t as sort key and \a key as main key. This is the reason
  why QCPCurve unlike QCPGraph can display parametric curves with loops.
 
  \li <tt>double mainKey() const</tt>\n Returns the variable of this data point considered the main
  key. This is commonly the variable that is used as the coordinate of this data point on the key
  axis of the plottable. This method is used for example when determining the automatic axis
  rescaling of key axes (\ref QCPAxis::rescale).
 
  \li <tt>double mainValue() const</tt>\n Returns the variable of this data point considered the
  main value. This is commonly the variable that is used as the coordinate of this data point on
  the value axis of the plottable.
 
  \li <tt>QCPRange valueRange() const</tt>\n Returns the range this data point spans in the value
  axis coordinate. If the data is single-valued (e.g. QCPGraphData), this is simply a range with
  both lower and upper set to the main data point value. However if the data points can represent
  multiple values at once (e.g QCPFinancialData with its \a high, \a low, \a open and \a close
  values at each \a key) this method should return the range those values span. This method is used
  for example when determining the automatic axis rescaling of value axes (\ref
  QCPAxis::rescale).

/*! \class QCPPlottableInterface1D
  \brief Defines an abstract interface for one-dimensional plottables
 
  This class contains only pure virtual methods which define a common interface to the data
  of one-dimensional plottables.
 
  For example, it is implemented by the template class \ref QCPAbstractPlottable1D (the preferred
  base class for one-dimensional plottables). So if you use that template class as base class of
  your one-dimensional plottable, you won't have to care about implementing the 1d interface
  yourself.
 
  If your plottable doesn't derive from \ref QCPAbstractPlottable1D but still wants to provide a 1d
  interface (e.g. like \ref QCPErrorBars does), you should inherit from both \ref
  QCPAbstractPlottable and \ref QCPPlottableInterface1D and accordingly reimplement the pure
  virtual methods of the 1d interface, matching your data container. Also, reimplement \ref
  QCPAbstractPlottable::interface1D to return the \c this pointer.
 
  If you have a \ref QCPAbstractPlottable pointer, you can check whether it implements this
  interface by calling \ref QCPAbstractPlottable::interface1D and testing it for a non-zero return
  value. If it indeed implements this interface, you may use it to access the plottable's data
  without needing to know the exact type of the plottable or its data point type.

*/
 
/*! \fn virtual QCPDataSelection QCPPlottableInterface1D::selectTestRect(const QRectF &rect, bool onlySelectable) const = 0;
  
  Returns a data selection containing all the data points of this plottable which are contained (or
  hit by) \a rect. This is used mainly in the selection rect interaction for data selection (\ref
  dataselection "data selection mechanism").
  
  If \a onlySelectable is true, an empty QCPDataSelection is returned if this plottable is not
  selectable (i.e. if \ref QCPAbstractPlottable::setSelectable is \ref QCP::stNone).
  
  \note \a rect must be a normalized rect (positive or zero width and height). This is especially
  important when using the rect of \ref QCPSelectionRect::accepted, which is not necessarily
  normalized. Use <tt>QRect::normalized()</tt> when passing a rect which might not be normalized.

/*! \fn virtual QPointF QCPPlottableInterface1D::dataPixelPosition(int index) const = 0
 
  Returns the pixel position on the widget surface at which the data point at the given \a index
  appears.
 
  Usually this corresponds to the point of \ref dataMainKey/\ref dataMainValue, in pixel
  coordinates. However, depending on the plottable, this might be a different apparent position
  than just a coord-to-pixel transform of those values. For example, \ref QCPBars apparent data
  values can be shifted depending on their stacking, bar grouping or configured base value.

  \a sortKey. If \a expandedRange is true, the data point just below \a sortKey will be considered,
  otherwise the one just above.
 
  This can be used in conjunction with \ref findEnd to iterate over data points within a given key
  range, including or excluding the bounding data points that are just beyond the specified range.
 
  If \a expandedRange is true but there are no data points below \a sortKey, 0 is returned.
 
  If the container is empty, returns 0 (in that case, \ref findEnd will also return 0, so a loop
  using these methods will not iterate over the index 0).

  considered, otherwise the one just below.

/*! \class QCPAbstractPlottable1D
  \brief A template base class for plottables with one-dimensional data
 
  This template class derives from \ref QCPAbstractPlottable and from the abstract interface \ref
  QCPPlottableInterface1D. It serves as a base class for all one-dimensional data (i.e. data with
  one key dimension), such as \ref QCPGraph and QCPCurve.
 
  The template parameter \a DataType is the type of the data points of this plottable (e.g. \ref
  QCPGraphData or \ref QCPCurveData). The main purpose of this base class is to provide the member
  \a mDataContainer (a shared pointer to a \ref QCPDataContainer "QCPDataContainer<DataType>") and
  implement the according virtual methods of the \ref QCPPlottableInterface1D, such that most
  subclassed plottables don't need to worry about this anymore.
 
  Further, it provides a convenience method for retrieving selected/unselected data segments via
  \ref getDataSegments. This is useful when subclasses implement their \ref draw method and need to
  draw selected segments with a different pen/brush than unselected segments (also see \ref
  QCPSelectionDecorator).
 
  This class implements basic functionality of \ref QCPAbstractPlottable::selectTest and \ref
  QCPPlottableInterface1D::selectTestRect, assuming point-like data points, based on the 1D data
  interface. In spite of that, most plottable subclasses will want to reimplement those methods
  again, to provide a more accurate hit test based on their specific data visualization geometry.
