A plottable that adds a set of error bars to other plottables.
The QCPErrorBars plottable can be attached to other one-dimensional plottables (e.g. QCPGraph, QCPCurve, QCPBars, etc.) and equips them with error bars.
Use setDataPlottable to define for which plottable the QCPErrorBars shall display the error bars. The orientation of the error bars can be controlled with setErrorType.
By using setData, you can supply the actual error data, either as symmetric error or plus/minus asymmetric errors. QCPErrorBars only stores the error data. The absolute key/value position of each error bar will be adopted from the configured data plottable. The error data of the QCPErrorBars are associated one-to-one via their index to the data points of the data plottable. You can directly access and manipulate the error bar data via data.
Set either of the plus/minus errors to NaN (qQNaN()
or std::numeric_limits<double>::quiet_NaN()
) to not show the respective error bar on the data point at that index.
The appearance of the error bars is defined by the pen (setPen), and the width of the whiskers (setWhiskerWidth). Further, the error bar backbones may leave a gap around the data point center to prevent that error bars are drawn too close to or even through scatter points. This gap size can be controlled via setSymbolGap.

Constructs an error bars plottable 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.
It is also important that the keyAxis and valueAxis are the same for the error bars plottable and the data plottable that the error bars shall be drawn on (setDataPlottable).
The created QCPErrorBars is automatically registered with the QCustomPlot instance inferred from keyAxis. This QCustomPlot instance takes ownership of the QCPErrorBars, so do not delete it manually but use QCustomPlot::removePlottable() instead.

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.

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).

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.

Replaces the current data container with the provided data container.
Since a QSharedPointer is used, multiple QCPErrorBars instances may share the same data container safely. Modifying the data in the container will then affect all QCPErrorBars instances 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, assign the data containers directly:
(This uses different notation compared with other plottables, because the QCPErrorBars uses a QVector<QCPErrorBarsData>
as its data container, instead of a QCPDataContainer.)
Definicja w linii 27235 pliku qcustomplot.cpp.
void QCPErrorBars::setDataPlottable | ( | QCPAbstractPlottable * | plottable | ) |
Sets the data plottable to which the error bars will be applied. The error values specified e.g. via setData will be associated one-to-one by the data point index to the data points of plottable. This means that the error bars will adopt the key/value coordinates of the data point with the same index.
The passed plottable must be a one-dimensional plottable, i.e. it must implement the QCPPlottableInterface1D. Further, it must not be a QCPErrorBars instance itself. If either of these restrictions is violated, a corresponding qDebug output is generated, and the data plottable of this QCPErrorBars instance is set to zero.
For proper display, care must also be taken that the key and value axes of the plottable match those configured for this QCPErrorBars instance.
