Detailed Description

An area graph is used to draw an area composed by points. The points are defined by two series: upperSeries and lowerSeries. The area between the series is drawn as a graph. If only the upperSeries is defined, the area is then between the bottom of the graph and the upper series.

Property Documentation

borderColor : QColor

This property holds the border color of the area. The default value is Qt::transparent, meaning the border color is defined by the theme.

Access functions:

QColor borderColor() const
void setBorderColor(QColor newBorderColor)

Notifier signal:

void borderColorChanged(QColor newBorderColor)

borderWidth : qreal

This property holds the width of the line that encloses the area. The default value is -1, meaning the border width is defined by the theme.

Access functions:

qreal borderWidth() const
void setBorderWidth(qreal newBorderWidth)

Notifier signal:

void borderWidthChanged()

color : QColor

This property holds the fill color of the area. The default value is Qt::transparent, meaning the color is defined by the theme.

Note: If gradient is set to something other than null, these will take precedence over color. The color will be ignored in this case.

Access functions:

QColor color() const
void setColor(QColor newColor)

Notifier signal:

void colorChanged(QColor newColor)

[since 6.11] gradient : QQuickShapeGradient*

This property defines the fill gradient. By default no gradient is enabled and the value is null. In this case the fill will be based on the color property.

Note: The Gradient type cannot be used here. Rather, prefer using one of the advanced subtypes, like LinearGradient.

Note: If set to something other than null, the gradient will take precedence over color.

This property was introduced in Qt 6.11.

Access functions:

QQuickShapeGradient *gradient() const
void setGradient(QQuickShapeGradient *newGradient)

Notifier signal:

void gradientChanged(QQuickShapeGradient *)

lowerSeries : QXYSeries*

Sets the lower boundary of the area. If this is null, the graph bottom is considered the lower bound.

Access functions:

QXYSeries *lowerSeries() const
void setLowerSeries(QXYSeries *newLowerSeries)

Notifier signal:

void lowerSeriesChanged()

selected : bool

Sets this area as selected. The default value is false.

Access functions:

bool isSelected() const
void setSelected(bool newSelected)

Notifier signal:

void selectedChanged()

selectedBorderColor : QColor

This property holds the border color of the area when selected. The default value is Qt::transparent, meaning the selected border color is defined by the theme.

Access functions:

QColor selectedBorderColor() const
void setSelectedBorderColor(QColor newSelectedBorderColor)

Notifier signal:

void selectedBorderColorChanged(QColor newSelectedBorderColor)

selectedColor : QColor

This property holds the fill color of the area when selected. The default value is Qt::transparent, meaning the selected color is defined by the theme.

Note: If selectedGradient is set to something other than null, these will take precedence over selectedColor. The selectedColor will be ignored in this case.

Access functions:

QColor selectedColor() const
void setSelectedColor(QColor newColor)

Notifier signal:

void selectedColorChanged(QColor newSelectedColor)

[since 6.11] selectedGradient : QQuickShapeGradient*

This property defines the fill gradient of the area when selected. By default no gradient is enabled and the value is null. In this case the fill will be based on the selectedColor property.

Note: The Gradient type cannot be used here. Rather, prefer using one of the advanced subtypes, like LinearGradient.

Note: If set to something other than null, the selectedGradient will take precedence over selectedColor.

This property was introduced in Qt 6.11.

Access functions:

QQuickShapeGradient *selectedGradient() const
void setSelectedGradient(QQuickShapeGradient *newSelectedGradient)

Notifier signal:

void selectedGradientChanged(QQuickShapeGradient *)

upperSeries : QXYSeries*

Sets the upper boundary of the area. No area is drawn if this is null.

Access functions:

QXYSeries *upperSeries() const
void setUpperSeries(QXYSeries *newUpperSeries)

Notifier signal:

void upperSeriesChanged()
