Opis szczegółowy

QCPStatisticalBox.png

To plot data, assign it with the setData or addData functions. Alternatively, you can also access and modify the data via the data method, which returns a pointer to the internal QCPStatisticalBoxDataContainer.

Additionally each data point can itself have a list of outliers, drawn as scatter points at the key coordinate of the respective statistical box data point. They can either be set by using the respective addData method or accessing the individual data points through data, and setting the QVector<double> outliers of the data points directly.

Changing the appearance

The appearance of each data point box, ranging from the lower to the upper quartile, is controlled via setPen and setBrush. You may change the width of the boxes with setWidth in plot coordinates.

Each data point's visual representation also consists of two whiskers. Whiskers are the lines which reach from the upper quartile to the maximum, and from the lower quartile to the minimum. The appearance of the whiskers can be modified with: setWhiskerPen, setWhiskerBarPen, setWhiskerWidth. The whisker width is the width of the bar perpendicular to the whisker at the top (for maximum) and bottom (for minimum). If the whisker pen is changed, make sure to set the capStyle to Qt::FlatCap. Otherwise the backbone line might exceed the whisker bars by a few pixels due to the pen cap being not perfectly flat.

The median indicator line inside the box has its own pen, setMedianPen.

The outlier data points are drawn as normal scatter points. Their look can be controlled with setOutlierStyle

Usage

Like all data representing objects in QCustomPlot, the QCPStatisticalBox is a plottable (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.)

Usually, you first create an instance:

which registers it with the QCustomPlot instance of the passed axes. Note that this QCustomPlot instance takes ownership of the plottable, so do not delete it manually but use QCustomPlot::removePlottable() instead. The newly created plottable can be modified, e.g.:

Dokumentacja konstruktora i destruktora

QCPStatisticalBox::QCPStatisticalBox ( QCPAxis keyAxis,
QCPAxis valueAxis 
)
explicit

Constructs a statistical box which uses keyAxis as its key axis ("x") and valueAxis as its value axis ("y"). keyAxis and valueAxis must reside in the same QCustomPlot instance and not have the same orientation. If either of these restrictions is violated, a corresponding message is printed to the debug output (qDebug), the construction is not aborted, though.

The created QCPStatisticalBox is automatically registered with the QCustomPlot instance inferred from keyAxis. This QCustomPlot instance takes ownership of the QCPStatisticalBox, so do not delete it manually but use QCustomPlot::removePlottable() instead.

)

To jest metoda przeciążona, udostępniona dla wygody. Różni się od powyższej metody tylko zestawem akceptowanych argumentów.

Adds the provided points in keys, minimum, lowerQuartile, median, upperQuartile and maximum to the current data. The provided vectors should have equal length. Else, the number of added points will be the size of the smallest vector.

If you can guarantee that the passed data points are sorted by keys in ascending order, you can set alreadySorted to true, to improve performance by saving a sorting run.

Alternatively, you can also access and modify the data directly via the data method, which returns a pointer to the internal data container.

To jest metoda przeciążona, udostępniona dla wygody. Różni się od powyższej metody tylko zestawem akceptowanych argumentów.

Adds the provided data point as key, minimum, lowerQuartile, median, upperQuartile and maximum to the current data.

Alternatively, you can also access and modify the data directly via the data method, which returns a pointer to the internal data container.

QSharedPointer< QCPStatisticalBoxDataContainer > QCPStatisticalBox::data ( ) const
inline

Returns a shared pointer to the internal data storage of type QCPStatisticalBoxDataContainer. You may use it to directly manipulate the data, which may be more convenient and faster than using the regular setData or addData methods.

QCPRange QCPStatisticalBox::getKeyRange ( bool &  foundRange,
QCP::SignDomain  inSignDomain = QCP::sdBoth 
) const
virtual

Returns the coordinate range that all data in this plottable span in the key axis dimension. For logarithmic plots, one can set inSignDomain to either QCP::sdNegative or QCP::sdPositive in order to restrict the returned range to that sign domain. E.g. when only negative range is wanted, set inSignDomain to QCP::sdNegative and all positive points will be ignored for range calculation. For no restriction, just set inSignDomain to QCP::sdBoth (default). foundRange is an output parameter that indicates whether a range could be found or not. If this is false, you shouldn't use the returned range (e.g. no points in data).

Note that foundRange is not the same as QCPRange::validRange, since the range returned by this function may have size zero (e.g. when there is only one data point). In this case foundRange would return true, but the returned range is not a valid range in terms of QCPRange::validRange.

QCPRange QCPStatisticalBox::getValueRange ( bool &  foundRange,
QCP::SignDomain  inSignDomain = QCP::sdBoth,
const QCPRange inKeyRange = QCPRange() 
) const
virtual

Returns the coordinate range that the data points in the specified key range (inKeyRange) span in the value axis dimension. For logarithmic plots, one can set inSignDomain to either QCP::sdNegative or QCP::sdPositive in order to restrict the returned range to that sign domain. E.g. when only negative range is wanted, set inSignDomain to QCP::sdNegative and all positive points will be ignored for range calculation. For no restriction, just set inSignDomain to QCP::sdBoth (default). foundRange is an output parameter that indicates whether a range could be found or not. If this is false, you shouldn't use the returned range (e.g. no points in data).

If inKeyRange has both lower and upper bound set to zero (is equal to QCPRange()), all data points are considered, without any restriction on the keys.

Note that foundRange is not the same as QCPRange::validRange, since the range returned by this function may have size zero (e.g. when there is only one data point). In this case foundRange would return true, but the returned range is not a valid range in terms of QCPRange::validRange.

double QCPStatisticalBox::selectTest ( const QPointF &  pos,

virtual

Implements a point-selection algorithm assuming the data (accessed via the 1D data interface) is point-like. Most subclasses will want to reimplement this method again, to provide a more accurate hit test based on the true data visualization geometry.

QCPDataSelection QCPStatisticalBox::selectTestRect ( const QRectF &  rect,
bool  onlySelectable 
) const
virtual

Returns a data selection containing all the data points of this plottable which are contained (or hit by) rect. This is used mainly in the selection rect interaction for data selection (data selection mechanism).

If onlySelectable is true, an empty QCPDataSelection is returned if this plottable is not selectable (i.e. if QCPAbstractPlottable::setSelectable is QCP::stNone).

Nota
rect must be a normalized rect (positive or zero width and height). This is especially important when using the rect of QCPSelectionRect::accepted, which is not necessarily normalized. Use QRect::normalized() when passing a rect which might not be normalized.

void QCPStatisticalBox::setData ( QSharedPointer< QCPStatisticalBoxDataContainer data)

To jest metoda przeciążona, udostępniona dla wygody. Różni się od powyższej metody tylko zestawem akceptowanych argumentów.

Replaces the current data container with the provided data container.

Since a QSharedPointer is used, multiple QCPStatisticalBoxes may share the same data container safely. Modifying the data in the container will then affect all statistical boxes that share the container. Sharing can be achieved by simply exchanging the data containers wrapped in shared pointers:

If you do not wish to share containers, but create a copy from an existing container, rather use the QCPDataContainer<DataType>::set method on the statistical box data container directly:
