class pyecharts.charts.Pie
class Pie(
# 初始化配置项，参考 `global_options.InitOpts`
init_opts: opts.InitOpts = opts.InitOpts()
)
func pyecharts.charts.Pie.add
def add(
# 系列名称，用于 tooltip 的显示，legend 的图例筛选。
series_name: str,
# 系列数据项，格式为 [(key1, value1), (key2, value2)]
data_pair: Sequence,
# 系列 label 颜色
color: Optional[str] = None,
# 饼图的半径，数组的第一项是内半径，第二项是外半径
# 默认设置成百分比，相对于容器高宽中较小的一项的一半
radius: Optional[Sequence] = None,
# 饼图的中心（圆心）坐标，数组的第一项是横坐标，第二项是纵坐标
# 默认设置成百分比，设置成百分比时第一项是相对于容器宽度，第二项是相对于容器高度
center: Optional[Sequence] = None,
# 是否展示成南丁格尔图，通过半径区分数据大小，有'radius'和'area'两种模式。
# radius：扇区圆心角展现数据的百分比，半径展现数据的大小
# area：所有扇区圆心角相同，仅通过半径展现数据大小
rosetype: Optional[str] = None,
# 饼图的扇区是否是顺时针排布。
is_clockwise: bool = True,
# 标签配置项，参考 `series_options.LabelOpts`
label_opts: Union[opts.LabelOpts, dict] = opts.LabelOpts(),
# 提示框组件配置项，参考 `series_options.TooltipOpts`
tooltip_opts: Union[opts.TooltipOpts, dict, None] = None,
# 图元样式配置项，参考 `series_options.ItemStyleOpts`
itemstyle_opts: Union[opts.ItemStyleOpts, dict, None] = None,
# 可以定义 data 的哪个维度被编码成什么。
encode: types.Union[types.JSFunc, dict, None] = None,
