# `Filled`

Filled or transparent areas and surfaces

MuPAD® notebooks are not recommended. Use MATLAB® live scripts instead.

MATLAB live scripts support most MuPAD functionality, though there are some differences. For more information, see Convert MuPAD Notebooks to MATLAB Live Scripts.

## Value Summary

 Inherited `FALSE`, or `TRUE`

## Description

`Filled` controls whether areas and surfaces are filled or transparent.

With `Filled = FALSE`, areas and surfaces are not filled. This means that, e.g., a surface plot is reduced to a wire frame model.

## Examples

### Example 1

The following parametrization of a sphere uses a mesh similar to the graticule (longitudes and latitudes) of geography:

```globe := plot::Surface([sin(u)*cos(v), cos(u)*cos(v), sin(v)], u = 0..2*PI, v = 0..2*PI, Mesh = [12, 12], Submesh = [3, 3]): plot(globe, Scaling = Constrained)```

To get a wire frame model, we set `Filled = FALSE`:

```plot(globe, Filled = FALSE, LineColor = RGB::Black, Scaling = Constrained)```
