# Attributes

Plot attributes configure plot layout and scales, including resulting axes and legends.
Attributes are included as plot directives, in the form of functions that take either a literal attribute value or a [`Param`](../core/param) as input.

**(begin JavaScript API)**

In addition to value arrays, scale domain attributes accept the `Fixed` symbol.

**(end JavaScript API)**

**(begin Python API)**

In addition to value arrays, scale domain attributes accept the string `"Fixed"` for a fixed domain (for example `vg.x_domain("Fixed")`).

**(end Python API)**

This setting indicates that the scale domain should first be determined by the data, but should then be held fixed across subsequent data updates.
A fixed domain will remain stable, preventing "jumps" in a display that might hamper interpretation of changes.

For additional documentation of scale attributes, see the corresponding [Observable Plot documentation](https://observablehq.com/plot/features/scales#scale-options).

**(begin JavaScript API)**

Attributes are passed as directives to `plot`, together with marks, interactors, and legends:

```js
plot(
  width(640),
  height(400),
  marginLeft(48),
  xDomain(Fixed),
  colorScheme("blues")
)
```

**(end JavaScript API)**

**(begin Python API)**

Attributes are passed as directives to `vg.plot`, together with marks, interactors, and legends:

```python
import vgplot as vg

vg.plot(
    vg.width(640),
    vg.height(400),
    vg.margin_left(48),
    vg.x_domain("Fixed"),
    vg.color_scheme("blues"),
)
```

## Projection Attributes

For more on projections, see the [Observable Plot projection documentation](https://observablehq.com/plot/features/projections).

* `projection_type(value)`: Set the projection type, such as `"mercator"`, `"orthographic"`.
* `projection_parallels(value)`: Set the [standard parallels](https://github.com/d3/d3-geo/blob/main/README.md#conic_parallels) (for conic projections only).
* `projection_precision(value)`: Set the [sampling threshold](https://github.com/d3/d3-geo/blob/main/README.md#projection_precision).
* `projection_rotate(value)`: Set a two- or three- element array of Euler angles to rotate the sphere.
* `projection_domain(value)`: Set a GeoJSON object to fit in the center of the (inset) frame.
* `projection_inset(value)`: Set the inset to the given amount in pixels when fitting to the frame (default zero).
* `projection_inset_left(value)`: Set the inset from the left edge of the frame (defaults to `projection_inset`).
* `projection_inset_right(value)`: Set the inset from the right edge of the frame (defaults to `projection_inset`).
* `projection_inset_top(value)`: Set the inset from the top edge of the frame (defaults to `projection_inset`).
* `projection_inset_bottom(value)`: Set the inset from the bottom edge of the frame (defaults to `projection_inset`).
* `projection_clip(value)`: Set the projection clipping method. One of: `"frame"` or `true` (default) to clip to the extent of the frame (including margins but not insets), a number to clip to a great circle of the given radius in degrees centered around the origin, or `null` or `false` to disable clipping.

Interval interactors are not currently supported when cartographic projections are used.
