Detailed Description
class QCPAbstractPlottable1D< DataType >
A template base class for plottables with one-dimensional data.
This template class derives from QCPAbstractPlottable and from the abstract interface QCPPlottableInterface1D. It serves as a base class for all one-dimensional data (i.e. data with one key dimension), such as QCPGraph and QCPCurve.
The template parameter DataType is the type of the data points of this plottable (e.g. QCPGraphData or QCPCurveData). The main purpose of this base class is to provide the member mDataContainer (a shared pointer to a QCPDataContainer<DataType>) and implement the according virtual methods of the 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 getDataSegments. This is useful when subclasses implement their draw method and need to draw selected segments with a different pen/brush than unselected segments (also see QCPSelectionDecorator).
This class implements basic functionality of QCPAbstractPlottable::selectTest and 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.

Constructor & Destructor Documentation
◆ QCPAbstractPlottable1D()
| QCPAbstractPlottable1D< DataType >::QCPAbstractPlottable1D | ( | QCPAxis * | keyAxis, |
| QCPAxis * | valueAxis ) |
Forwards keyAxis and valueAxis to the QCPAbstractPlottable constructor and allocates the mDataContainer.

◆ ~QCPAbstractPlottable1D()

Definition at line 4411 of file qcustomplot.h.
Member Function Documentation
◆ dataCount()
|
overridevirtual |
Returns the number of data points of the plottable.
Implements QCPPlottableInterface1D.
Definition at line 4419 of file qcustomplot.h.
◆ dataMainKey()
|
overridevirtual |
Returns the main key of the data point at the given index.
What the main key is, is defined by the plottable's data type. See the QCPDataContainer DataType documentation for details about this naming convention.
Implements QCPPlottableInterface1D.
Definition at line 4428 of file qcustomplot.h.
◆ dataMainValue()
|
overridevirtual |
Returns the main value of the data point at the given index.
What the main value is, is defined by the plottable's data type. See the QCPDataContainer DataType documentation for details about this naming convention.
Implements QCPPlottableInterface1D.
Definition at line 4460 of file qcustomplot.h.
◆ dataPixelPosition()
|
overridevirtual |
Returns the pixel position on the widget surface at which the data point at the given index appears.
Usually this corresponds to the point of dataMainKey/ 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, QCPBars apparent data values can be shifted depending on their stacking, bar grouping or configured base value.
Implements QCPPlottableInterface1D.
Reimplemented in QCPBars.
Definition at line 4492 of file qcustomplot.h.
◆ dataSortKey()
|
overridevirtual |
Returns the sort key of the data point at the given index.
What the sort key is, is defined by the plottable's data type. See the QCPDataContainer DataType documentation for details about this naming convention.
Implements QCPPlottableInterface1D.
Definition at line 4444 of file qcustomplot.h.
◆ dataValueRange()
|
overridevirtual |
Returns the value range of the data point at the given index.
What the value range is, is defined by the plottable's data type. See the QCPDataContainer DataType documentation for details about this naming convention.
Implements QCPPlottableInterface1D.
Definition at line 4476 of file qcustomplot.h.
◆ drawPolyline()
|
protected |
A helper method which draws a line with the passed painter, according to the pixel data in lineData. NaN points create gaps in the line, as expected from QCustomPlot's plottables (this is the main difference to QPainter's regular drawPolyline, which handles NaNs by lagging or crashing).
Further it uses a faster line drawing technique based on QCPPainter::drawLine rather than QPainter::drawPolyline if the configured QCustomPlot::setPlottingHints() and painter style allows.
Definition at line 4688 of file qcustomplot.h.
◆ findBegin()
|
overridevirtual |
Returns the index of the data point with a (sort-)key that is equal to, just below, or just above sortKey. If expandedRange is true, the data point just below sortKey will be considered, otherwise the one just above.
This can be used in conjunction with 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 expandedRange is true but there are no data points below sortKey, 0 is returned.
If the container is empty, returns 0 (in that case, findEnd will also return 0, so a loop using these methods will not iterate over the index 0).

- findEnd, QCPDataContainer::findBegin
Implements QCPPlottableInterface1D.
Definition at line 4571 of file qcustomplot.h.
◆ findEnd()
|
overridevirtual |
Returns the index one after the data point with a (sort-)key that is equal to, just above, or just below sortKey. If expandedRange is true, the data point just above sortKey will be considered, otherwise the one just below.
This can be used in conjunction with findBegin to iterate over data points within a given key range, including the bounding data points that are just below and above the specified range.
If expandedRange is true but there are no data points above sortKey, the index just above the highest data point is returned.
If the container is empty, returns 0.

- findBegin, QCPDataContainer::findEnd
Implements QCPPlottableInterface1D.
Definition at line 4580 of file qcustomplot.h.
◆ getDataSegments()
|
protected |
Splits all data into selected and unselected segments and outputs them via selectedSegments and unselectedSegments, respectively.
This is useful when subclasses implement their draw method and need to draw selected segments with a different pen/brush than unselected segments (also see QCPSelectionDecorator).
- See also
- setSelection
Definition at line 4658 of file qcustomplot.h.
◆ interface1D()
|
inlineoverridevirtual |
Returns a QCPPlottableInterface1D pointer to this plottable, providing access to its 1D interface.
\seebaseclassmethod
Reimplemented from QCPAbstractPlottable.
Definition at line 4200 of file qcustomplot.h.
◆ selectTest()
|
overridevirtual |
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.
If details is not 0, it will be set to a QCPDataSelection, describing the closest data point to pos.
\seebaseclassmethod
Implements QCPAbstractPlottable.
Reimplemented in QCPBars, QCPCurve, QCPFinancial, QCPGraph, and QCPStatisticalBox.
Definition at line 4596 of file qcustomplot.h.
◆ selectTestRect()
|
overridevirtual |
Implements a rect-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.
\seebaseclassmethod
Implements QCPPlottableInterface1D.
Reimplemented in QCPBars, QCPFinancial, and QCPStatisticalBox.
Definition at line 4522 of file qcustomplot.h.
◆ sortKeyIsMainKey()
|
overridevirtual |
Returns whether the sort key (dataSortKey) is identical to the main key (dataMainKey).
What the sort and main keys are, is defined by the plottable's data type. See the QCPDataContainer DataType documentation for details about this naming convention.
Implements QCPPlottableInterface1D.
