Public Attributes

Type	Name
GradientFillBaseline	baseline = {GradientFillBaseline::AxisMinimum} Baseline mode.
qreal	baselineValue = {0.0} Fixed baseline data value when mode is Value .
Qt::Orientation	direction = {Qt::Horizontal} Gradient direction.
bool	enabled = {false} true when gradient fill is active.
std::optional< qreal >	gradientValueMax Fixed max for gradient normalisation; std::nullopt = derived from data range.
std::optional< qreal >	gradientValueMin Fixed min for gradient normalisation; std::nullopt = derived from data range.
float	opacity = {1.0f} Overall opacity of the fill in [0, 1].
std::vector< GradientStopData >	stops Color stops in position order.

Public Functions

Type	Name
bool	isValid () const Returns true if the payload has at least two stops, is enabled, and has non-zero opacity.

Detailed Description

Assembled on the main thread and consumed by the line renderer without touching the QObject hierarchy.
