## 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 : color

The border color of the area. The default value is `transparent`, meaning the border color is defined by the theme.

borderWidth : real

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

color : color

The fill color of the area. The default value is `transparent`, meaning the color is defined by the theme.

lowerSeries : XYSeries

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

selected : bool

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

selectedBorderColor : color

The border color of the area when selected. The default value is `transparent`, meaning the selected border color is defined by the theme.

selectedColor : color

The fill color of the area when selected. The default value is `transparent`, meaning the selected color is defined by the theme.

upperSeries : XYSeries

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

## Signal Documentation

borderColorChanged(color newBorderColor)

This signal is emitted when the area border color changes to newBorderColor.

Note: The corresponding handler is `onBorderColorChanged`.

borderWidthChanged()

This signal is emitted when the width of the area border width changes.

Note: The corresponding handler is `onBorderWidthChanged`.

colorChanged(color newColor)

This signal is emitted when the area color changes to newColor.

Note: The corresponding handler is `onColorChanged`.

lowerSeriesChanged()

This signal is emitted when the lower series changes.

Note: The corresponding handler is `onLowerSeriesChanged`.

selectedBorderColorChanged(color newSelectedBorderColor)

This signal is emitted when the border color of a selected area changes to newSelectedBorderColor.

Note: The corresponding handler is `onSelectedBorderColorChanged`.

selectedChanged()

This signal is emitted when the current area is selected.

Note: The corresponding handler is `onSelectedChanged`.

selectedColorChanged(color newSelectedColor)

This signal is emitted when the color of a selected area changes to newSelectedColor.

Note: The corresponding handler is `onSelectedColorChanged`.

upperSeriesChanged()

This signal is emitted when the upper series changes.

Note: The corresponding handler is `onUpperSeriesChanged`.
