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.

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.

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.

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).

This function is used to decide whether a click hits a layerable object or not.
pos is a point in pixel coordinates on the QCustomPlot surface. This function returns the shortest pixel distance of this point to the object. If the object is either invisible or the distance couldn't be determined, -1.0 is returned. Further, if onlySelectable is true and the object is not selectable, -1.0 is returned, too.
If the object is represented not by single lines but by an area like a QCPItemText or the bars of a QCPBars plottable, a click inside the area should also be considered a hit. In these cases this function thus returns a constant value greater zero but still below the parent plot's selection tolerance. (typically the selectionTolerance multiplied by 0.99).
Providing a constant value for area objects allows selecting line objects even when they are obscured by such area objects, by clicking close to the lines (i.e. closer than 0.99*selectionTolerance).
The actual setting of the selection state is not done by this function. This is handled by the parent QCustomPlot when the mouseReleaseEvent occurs, and the finally selected object is notified via the selectEvent/deselectEvent methods.
details is an optional output parameter. Every layerable subclass may place any information in details. This information will be passed to selectEvent when the parent QCustomPlot decides on the basis of this selectTest call, that the object was successfully selected. The subsequent call to selectEvent will carry the details. This is useful for multi-part objects (like QCPAxis). This way, a possibly complex calculation to decide which part was clicked is only done once in selectTest. The result (i.e. the actually clicked part) can then be placed in details. So in the subsequent selectEvent, the decision which part was selected doesn't have to be done a second time for a single selection operation.
You may pass 0 as details to indicate that you are not interested in those selection details.

This function is used to decide whether a click hits a layerable object or not.
pos is a point in pixel coordinates on the QCustomPlot surface. This function returns the shortest pixel distance of this point to the object. If the object is either invisible or the distance couldn't be determined, -1.0 is returned. Further, if onlySelectable is true and the object is not selectable, -1.0 is returned, too.
If the object is represented not by single lines but by an area like a QCPItemText or the bars of a QCPBars plottable, a click inside the area should also be considered a hit. In these cases this function thus returns a constant value greater zero but still below the parent plot's selection tolerance. (typically the selectionTolerance multiplied by 0.99).
Providing a constant value for area objects allows selecting line objects even when they are obscured by such area objects, by clicking close to the lines (i.e. closer than 0.99*selectionTolerance).
