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.

-
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

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
-
