class janim.items.coordinate.coordinate_systems.CoordinateSystem(*args, num_sampled_graph_points_per_tick, **kwargs)

基类：object

static create_axis(range: RangeSpecifier, axis_config: dict, length: float | None) → NumberLine

abstractmethod get_axes() → list[NumberLine]

get_origin() → ndarray

coords_to_point(*coords: float) → ndarray

传入坐标得到对应的位置

例如 c2p(1, 3) 得到 (1,3) 的位置

coords_array_to_points(coords_array: VectArray) → ndarray

传入一组坐标得到对应的一组位置

例如 c2p([[1, 3], [2, 1], [-1, -1]]) 得到对应的三个位置

c2p(*coords: float) → ndarray

coords_to_point() 的缩写

point_to_coords3d(point: Vect | Iterable[Vect]) → ndarray

传入位置得到对应的坐标（但是会扩张为三维坐标；对于二维坐标系来说，第三个分量则表示距离二维平面的距离）

也可以传入一组位置得到一组对应的坐标

p2c3d(point: Vect | Iterable[Vect]) → ndarray

point_to_coords3d() 的简写

point_to_coords(point: Vect | Iterable[Vect]) → ndarray

传入位置得到对应坐标

也可以传入一组位置得到一组对应的坐标

p2c(point: Vect | Iterable[Vect]) → ndarray

point_to_coords() 的缩写

number_to_point(number: complex | float) → ndarray

传入复数得到对应位置

n2p(number: complex | float) → ndarray

number_to_point() 的缩写

point_to_number(point: Vect) → complex

传入位置得到对应复数

p2n(point: Vect) → complex

point_to_number() 的缩写
