Opis szczegółowy

A plottable representing a financial stock chart.

This plottable represents time series data binned to certain intervals, mainly used for stock charts. The two common representations OHLC (Open-High-Low-Close) bars and Candlesticks can be set via setChartStyle.

The data is passed via setData as a set of open/high/low/close values at certain keys (typically times). This means the data must be already binned appropriately. If data is only available as a series of values (e.g. price against time), you can use the static convenience function timeSeriesToOhlc to generate binned OHLC-data which can then be passed to setData.

The width of the OHLC bars/candlesticks can be controlled with setWidth and setWidthType. A typical choice is to set the width type to wtPlotCoords (the default) and the width to (or slightly less than) one time bin interval width.

Changing the appearance

Charts can be either single- or two-colored (setTwoColored). If set to be single-colored, lines are drawn with the plottable's pen (setPen) and fills with the brush (setBrush).

If set to two-colored, positive changes of the value during an interval (close >= open) are represented with a different pen and brush than negative changes (close < open). These can be configured with setPenPositive, setPenNegative, setBrushPositive, and setBrushNegative. In two-colored mode, the normal plottable pen/brush is ignored. Upon selection however, the normal selected pen/brush (provided by the selectionDecorator) is used, irrespective of whether the chart is single- or two-colored.

Usage

Like all data representing objects in QCustomPlot, the QCPFinancial 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.:

Here we have used the static helper method timeSeriesToOhlc, to turn a time-price data series into a 24-hour binned open-high-low-close data series as QCPFinancial uses.

Dokumentacja konstruktora i destruktora

◆ QCPFinancial()

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

Constructs a financial chart 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 QCPFinancial is automatically registered with the QCustomPlot instance inferred from keyAxis. This QCustomPlot instance takes ownership of the QCPFinancial, 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, open, high, low and close 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.

◆ getKeyRange()

QCPRange QCPFinancial::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.

◆ getValueRange()

QCPRange QCPFinancial::getValueRange ( bool &  foundRange,

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.

QCPDataSelection QCPFinancial::selectTestRect ( const QRectF &  rect,

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.

Replaces the current data container with the provided data container.

Since a QSharedPointer is used, multiple QCPFinancials may share the same data container safely. Modifying the data in the container will then affect all financials 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 financial's data container directly:

◆ timeSeriesToOhlc()

QCPFinancialDataContainer QCPFinancial::timeSeriesToOhlc ( const QVector< double > &  time,
const QVector< double > &  value,
double  timeBinSize,
double  timeBinOffset = 0 
)
static

A convenience function that converts time series data (value against time) to OHLC binned data points. The return value can then be passed on to QCPFinancialDataContainer::set(const QCPFinancialDataContainer&).

The size of the bins can be controlled with timeBinSize in the same units as time is given. For example, if the unit of time is seconds and single OHLC/Candlesticks should span an hour each, set timeBinSize to 3600.

timeBinOffset allows to control precisely at what time coordinate a bin should start. The value passed as timeBinOffset doesn't need to be in the range encompassed by the time keys. It merely defines the mathematical offset/phase of the bins that will be used to process the data.
