The PointScale class maps categorical values to discrete points within the output range, with specified padding at both ends.

`pydreamplet.scales.PointScale`

PointScale(
    domain: list[Any],
    output_range: tuple[float, float],
    padding: float = 0.5
)

Parameters

domain (list[Any]): A list of categorical values (distinct).
output_range (tuple[float, float]): The numeric output range.
padding (float, optional): The amount of padding on each end (default: 0.5).

point = PointScale(["X", "Y", "Z"], (0, 100))
print(point.map("Y"))  # Outputs the point corresponding to "Y"

map(value: Any) -> float | None

Maps a categorical value to a discrete point; returns None if the value is not in the domain.

Get or set the list of categories.

Get or set the numeric output range.

Get or set the padding value.
