CircularSeries<T, D> class

This class holds the property of circular series.

To render the Circular chart, create an instance of PieSeries or DoughnutSeries or RadialBarSeries, and add it to the series collection property of SfCircularChart. You can use the radius property to change the diameter of the circular chart for the plot area. Also, explode the circular chart segment by enabling the explode property.

Provide the options of stroke width, stroke color, opacity, and point color mapper 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.
final
animationDuration double
Duration for animating the data points.
final
borderColor Color
Border color of the data points in the series.
final
borderWidth double
Border width of the data points in the series.
final
cornerStyle CornerStyle
Specifies the radial bar’s corner type.
final
dataLabelMapper ChartIndexedValueMapper<String>?
Maps the field name, which will be considered as a text for the data points.
final
dataLabelSettings DataLabelSettings
Customizes the data labels in a series. Data label is a text, which displays the details about the data point.
final
dataSource List<T>?
A collection of data required for rendering the series.
final
emptyPointSettings EmptyPointSettings
Customizes the empty data points in the series.
final
enableTooltip bool
Determines whether to enable tooltip.
final
endAngle int
Ending angle of the series.
final
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.
final
groupMode CircularChartGroupMode?
Slice can also be grouped based on the data points value or based on index.
final
groupTo double?
Groups the data points of the series based on their index or values.
final
hashCode int
The hash code for this object.
no setterinherited
initialSelectedDataIndexes List<int>
List of data indexes initially selected.
getter/setter pair
innerRadius String
Inner radius of the series.
final

finalinherited
key ValueKey<String>?
Key to identify a series in a collection.
final
legendIconType LegendIconType
Shape of the legend icon.
final
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
name String?
Name of the series.
final
onCreateRenderer ChartSeriesRendererFactory<T, D>?
Used to create the renderer for custom series.
final
onPointDoubleTap ChartPointInteractionCallback?
Called when double tapped on the chart data point.
final
onPointLongPress ChartPointInteractionCallback?
Called when long pressed on the chart data point.
final
onPointTap ChartPointInteractionCallback?
Called when tapped on the chart data point.
final
onRendererCreated CircularSeriesRendererCreatedCallback?

final
opacity double
Opacity of the series. The value ranges from 0 to 1.
final
pointColorMapper ChartIndexedValueMapper<Color>?
Maps the field name, which will be considered as data point color.
final
pointRadiusMapper ChartIndexedValueMapper<String>?
Maps the field name, which will be considered for calculating the radius of all the data points.
final
pointRenderMode PointRenderMode?
Defines the painting mode of the data points.
final
