Detailed Description

class QQPlot : public Plot 

This class implements the Q-Q plot - a visualization of that is used to compare two probability distributions by plotting their quantiles against each other.

The provided data set can be compared with one of the distributions implemented in NSL. The visual properties of the plotted reference line and the percentile values can be modified independently of each other.

Public Functions

virtual QIcon icon() const override: Returns an icon to be used in the project explorer.

virtual void save(QXmlStreamWriter*) const override: Save as XML.

virtual bool load(XmlStreamReader*, bool preview) override: Load from XML.

virtual void setVisible(bool) override: Show/hide the element.

virtual bool hasData() const override: returns true if a valid data column is set, returns false otherwise. Used in CartesianPlot to determine whether the curve needs to be taken into account when calculating the data ranges of the plot area.

virtual void handleAspectUpdated(const QString &aspectPath, const AbstractAspect *element) override

handleAspectUpdated in some cases one aspect can depend on another, like a XYCurve on Column or InfoElement on XYCurve. This is a generic function called for all Elements when a new aspect will be added even it is not a child of the current element

Path is explicit specified, so it must not be recalculated every time when iterating over multiple WorksheetElements. The path is the same as aspect->path()
