AreaSeries<T, D> class

This class renders the area series.

To render an area chart, create an instance of AreaSeries, and add it to the series collection property of SfCartesianChart. The area chart shows the filled area to represent the data, but when there are more than a series, this may hide the other series. To get rid of this, increase or decrease the transparency of the series.

It provides options for color, opacity, border color, and border width to customize the appearance.

Properties

animationDelay → double
Delay duration of the series animation.It takes a millisecond value as input. By default, the series will get animated for the specified duration. If animationDelay is specified, then the series will begin to animate after the specified duration.
finalinherited
animationDuration → double
Duration of the series animation. It takes millisecond value as input.
finalinherited
borderColor → Color
final
borderDrawMode → BorderDrawMode
Border type of area series.
final
borderGradient → LinearGradient?
Fills the border of the chart series with gradient color.
finalinherited
borderWidth → double
Border width of the series.
finalinherited
color → Color?
Color of the series.
finalinherited
dashArray → List<double>?
Dashes of the series.
finalinherited
dataLabelMapper → ChartValueMapper<T, String>?
Field in the data source, which is considered as text for the data points.
finalinherited
dataLabelSettings → DataLabelSettings
Customizes the data labels in a series. Data label is a text, which displays the details about the data point.
finalinherited
dataSource → List<T>?
Data required for rendering the series. If no data source is specified, empty chart will be rendered without series.
finalinherited
emptyPointSettings → EmptyPointSettings
Customizes the empty points, i.e. null data points in a series.
finalinherited
enableTooltip → bool
Enables or disables the tooltip for this series. Tooltip will display more details about data points when tapping the data point region.
finalinherited
enableTrackball → bool
Enables or disables the trackball for this series. Trackball will display more details about data points when tapping the data point region.
finalinherited
gradient → LinearGradient?
Fills the chart series with gradient color.
finalinherited
hashCode → int
The hash code for this object.
no setterinherited
initialIsVisible → bool
Visibility of the series, which applies only during load time.
finalinherited
initialSelectedDataIndexes → List<int>?
List of data indexes to initially be selected.
finalinherited
isVisibleInLegend → bool
Toggles the visibility of the legend item of this specific series in the legend.
finalinherited
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
legendIconType → LegendIconType
Shape of the legend icon. Any shape in the LegendIconType can be applied to this property. By default, icon will be rendered based on the type of the series.
finalinherited
legendItemText → String?
Text to be displayed in legend. By default, the series name will be displayed in the legend. You can change this by setting values to this property.
finalinherited
markerSettings → MarkerSettings
Indication of data points.
finalinherited
name → String?
Name of the series. The name will be displayed in legend item by default. If name is not specified for the series, then the current series index with ‘series’ text prefix will be considered as series name.
finalinherited
onCreateRenderer → ChartSeriesRendererFactory<T, D>?
Used to create the renderer for custom series.
finalinherited
onCreateShader → CartesianShaderCallback?
Fills the data points with the gradient and image shaders.
finalinherited
onPointDoubleTap → ChartPointInteractionCallback?
Called when double tapped on the chart data point.
finalinherited
onPointLongPress → ChartPointInteractionCallback?
Called when long pressed on the chart data point.
finalinherited
onPointTap → ChartPointInteractionCallback?
Called when tapped on the chart data point.
finalinherited
onRendererCreated → SeriesRendererCreatedCallback<T, D>?
Triggers when the series renderer is created.
finalinherited
opacity → double
Opacity of the series. The value ranges from 0 to 1.
finalinherited
pointColorMapper → ChartValueMapper<T, Color>?
Field in the data source, which is considered as fill color for the data points.
finalinherited
positions → List<ChartDataPointType>
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
selectionBehavior → SelectionBehavior?
Customizes the data points or series on selection.

Customizes the trendlines.
finalinherited
xAxisName → String?
Name of the x-axis to bind the series.
finalinherited
