# scale_shape_manual

Custom discrete shape scale

## Signature

`scale_shape_manual( values, *, name=None, breaks=True, limits=None, labels=True, expand=None, guide="legend", na_value=np.nan, aesthetics=(), drop=True, na_translate=True )`

## Parameters

| Param | Type | Default | Description |
|-------|------|---------|-------------|
| `values` | Sequence[Any] \| dict[Any, Any] |  | Shapes that make up the palette. See matplotlib.markers for list of all possible shapes. The values will be matched with the limits of the scale or the breaks if provided. If it is a dict then it should map data values to shapes. |
| `name` | str \| None | `None` | The name of the scale. It is used as the label of the axis or the title of the guide. Suitable defaults are chosen depending on the type of scale. |
| `breaks` | DiscreteBreaksUser | `True` | List of major break points. Or a callable that takes a tuple of limits and returns a list of breaks. If True, automatically calculate the breaks. |
| `limits` | DiscreteLimitsUser | `None` | Limits of the scale. These are the categories (unique values) of the variables. If is only a subset of the values, those that are left out will be treated as missing data and represented with a na_value. |
| `labels` | ScaleLabelsUser | `True` | Labels at the breaks. Alternatively, a callable that takes an array_like of break points as input and returns a list of strings. |
| `expand` | ( tuple[float, float] \| tuple[float, float, float, float] \| None) | `None` | Multiplicative and additive expansion constants that determine how the scale is expanded. If specified must be of length 2 or 4. Specifically the values are in this order: For example, If not specified, suitable defaults are chosen. |
| `guide` | Literal["legend"] \| None | `"legend"` |  |
| `na_value` | Any | `np.nan` | If na_translate=True, what aesthetic value should be assigned to the missing values. This parameter does not apply to position scales where nan is always placed on the right. |
| `aesthetics` | Sequence[ScaledAestheticsName] | `()` | Aesthetics affected by this scale. These are defined by each scale and the user should probably not change them. Have fun. |
| `drop` | bool | `True` | Whether to drop unused categories from the scale |
| `na_translate` | bool | `True` | If True translate missing values and show them. If False remove missing values. |
