PieSeries<T, D> class

This class has the properties of the pie series.

To render a pie chart, create an instance of PieSeries, and add it to the series collection property of SfCircularChart.

It provides the 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
Border color of the series.
finalinherited
borderWidth → double
Border width of the series.
finalinherited
color → Color?
Color of the series.
finalinherited
cornerStyle → CornerStyle
Specifies the radial bar’s corner type.
finalinherited
dataLabelMapper → ChartValueMapper<T, String>?

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
endAngle → int
Ending angle of the series.
finalinherited
explode → bool
Enables or disables the explode of slices on tap.
final
explodeAll → bool
Enables or disables exploding all the slices at the initial rendering.
final
explodeGesture → ActivationMode
Gesture for activating the explode.
final
explodeIndex → int?
Index of the slice to explode it at the initial rendering.
final
explodeOffset → String
Offset of exploded slice. The value ranges from 0% to 100%.
final
gap → String
Specifies the gap between the radial bars in percentage.
finalinherited
groupMode → CircularChartGroupMode?
Slice can also be grouped based on the data points value or based on index.
finalinherited
groupTo → double?
Groups the data points of the series based on their index or values.
finalinherited
hashCode → int
The hash code for this object.
no setterinherited
initialIsVisible → bool
Visibility of the series.
finalinherited
initialSelectedDataIndexes → List<int>?
List of data indexes to initially be selected.
finalinherited
innerRadius → String
Inner radius of the series.
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 → CircularShaderCallback?
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 → CircularSeriesRendererCreatedCallback<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
pointRadiusMapper → ChartValueMapper<T, String>?
Maps the field name, which will be considered for calculating the radius of all the data points.
finalinherited

finalinherited
sortingOrder → SortingOrder
The data points in the series can be sorted in ascending or descending order. The data points will be rendered in the specified order if it is set to none.
