Public Properties inherited from QAccelPlot::DataTransition¶

See QAccelPlot::DataTransition

Type	Name
property QML_ANONYMOUSint	duration Duration of the transition in milliseconds. Default: 300.
property QEasingCurve	easing Easing curve applied to the animation progress. Default: `QEasingCurve::Linear` .
property bool	enabled Whether the transition is active. When `false` , data updates are applied instantly.
property bool	running Read-only: `true` while the transition is playing on at least one element.

Public Signals inherited from QAccelPlot::DataTransition¶

See QAccelPlot::DataTransition

Type	Name
signal void	durationChanged Emitted when the duration property changes.
signal void	easingChanged Emitted when the easing property changes.
signal void	enabledChanged Emitted when the enabled property changes.
signal void	runningChanged Emitted when the running property changes.

Public Functions¶

Type	Name
	MorphTransition (QObject * parent=nullptr) Constructs a MorphTransition with the given__parent .

Public Functions inherited from QAccelPlot::DataTransition¶

See QAccelPlot::DataTransition

Type	Name
	DataTransition (QObject * parent=nullptr) Constructs an DataTransition with the given__parent .
bool	advance (Run & run, std::vector< double > & outData, int & outPointCount) Advances run by one frame, writing the interpolated data into__outData .
void	cancel () Ends every active run immediately.
int	duration () const Returns the animation duration in milliseconds.
QEasingCurve	easing () const Returns the easing curve.
bool	enabled () const Returns `true` if the transition is enabled.
bool	running () const Returns `true` while at least one run is active.
void	setDuration (int duration) Sets the animation duration to duration milliseconds.
void	setEasing (const QEasingCurve & easing) Sets the easing curve to easing .
void	setEnabled (bool enabled) Sets the enabled state to enabled .
void	start (Run & run, const std::vector< double > & currentData, int currentPointCount, std::vector< double > && newData, int newPointCount, int stride=2) Starts run from__currentData to__newData , restarting it if it is already active.
	~DataTransition () override Destroys the transition. Its runs stay pending, so their hosts can still show the target data.

Public Static Functions¶

Type	Name
double	interpolateCoordinate (double from, double to, double easedProgress) Returns the coordinate between from and__to at__easedProgress , honoring the invalid-data-point contract.

Protected Functions¶

Type	Name
virtual void	interpolate (double easedProgress, const Dataset & from, const Dataset & to, Dataset & out) override Interpolates every value of every point between from and__to at__easedProgress .

Protected Functions inherited from QAccelPlot::DataTransition¶

See QAccelPlot::DataTransition

Type	Name
virtual void	interpolate (double easedProgress, const Dataset & from, const Dataset & to, Dataset & out) = 0 Subclass entry point — writes the dataset between from and__to at__easedProgress into__out .

Detailed Description¶

Each point is linearly blended from its old position to its new position. When the point counts differ, the extra points start from, or end on, the last point of the shorter dataset. BarSeries grows and shrinks such bars at its baseline instead, and PointCloud shows or removes such points at once. Non-finite coordinates are never interpolated: an invalid target coordinate is applied immediately, and a valid target coordinate replaces an invalid source coordinate without animation.
