RadialBarSeries<T, D> class

Renders the radial bar series.

The radial bar chart is used for showing the comparisons among the categories using the circular shapes. To render a radial bar chart, create an instance of RadialBarSeries, and add to the series collection property of SfCircularChart.

Provides options to customize the maximumValue, trackColor, trackBorderColor, trackBorderWidth, trackOpacity and useSeriesColor of the radial segments.

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 for animating the data points.
finalinherited
borderColor → Color
Border color of the data points in the series.
finalinherited
borderWidth → double
Border width of the data points in the series.
finalinherited
cornerStyle → CornerStyle
Specifies the radial bar’s corner type.
finalinherited
dataLabelMapper → ChartIndexedValueMapper<String>?
Maps the field name, which will be considered as a 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>?
A collection of data required for rendering the series.
finalinherited
emptyPointSettings → EmptyPointSettings
Customizes the empty data points in the series.
finalinherited
enableTooltip → bool
Determines whether to enable tooltip.
finalinherited
endAngle → int
Ending angle of the series.
finalinherited
explode → bool
Enables or disables the explode of slices on tap.
finalinherited
explodeAll → bool
Enables or disables exploding all the slices at the initial rendering.
finalinherited
explodeGesture → ActivationMode
Gesture for activating the explode.
finalinherited
explodeIndex → int?
Index of the slice to explode it at the initial rendering.
finalinherited
explodeOffset → String
Offset of exploded slice. The value ranges from 0% to 100%.
finalinherited
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 setteroverride
initialSelectedDataIndexes ↔ List<int>
List of data indexes initially selected.
getter/setter pairinherited
innerRadius → String
Inner radius of the series.
finalinherited
isVisible → bool?
Visibility of the series.
finalinherited
key → ValueKey<String>?
Key to identify a series in a collection.
finalinherited
legendIconType → LegendIconType
Shape of the legend icon.
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
maximumValue → double?
Specifies the maximum value of the radial bar.
final
name → String?
Name of the series.
finalinherited
onCreateRenderer → ChartSeriesRendererFactory<T, D>?
Used to create the renderer for custom series.
finalinherited
onPointDoubleTap → ChartPointInteractionCallback?
Called when double tapped on the chart data point.
finalinherited
onPointLongPress → ChartPointInteractionCallback?

finalinherited
onPointTap → ChartPointInteractionCallback?
Called when tapped on the chart data point.
finalinherited
onRendererCreated → CircularSeriesRendererCreatedCallback?
Triggers when the series renderer is created.
finalinherited
opacity → double
Opacity of the series. The value ranges from 0 to 1.
finalinherited
pointColorMapper → ChartIndexedValueMapper<Color>?
Maps the field name, which will be considered as data point color.
finalinherited
pointRadiusMapper → ChartIndexedValueMapper<String>?
Maps the field name, which will be considered for calculating the radius of all the data points.
