title: Area Chart
---
-Both [line](line.md) and [radar](radar.md) charts support a `fill` option on the dataset object which can be used to create space between two datasets or a dataset and a boundary, i.e. the scale `origin`, `start,` or `end` (see [filling modes](#filling-modes)).

> **Note:** this feature is implemented by the [`filler` plugin](https://github.com/chartjs/Chart.js/blob/master/src/plugins/plugin.filler.js).
## Dataset Properties
-The scatter chart supports all of the same properties as the [line chart](./line.md#dataset-properties).

## Data Structure
| `borderDashOffset` | `number` | `0.0` | Line dash offset. See [MDN](https://developer.mozilla.org/en-US/docs/Web/API/CanvasRenderingContext2D/lineDashOffset).
| `borderJoinStyle` | `string` | `'miter'` | Line join style. See [MDN](https://developer.mozilla.org/en-US/docs/Web/API/CanvasRenderingContext2D/lineJoin).
| `capBezierPoints` | `boolean` | `true` | `true` to keep Bézier control inside the chart, `false` for no restriction.
-| `cubicInterpolationMode` | `string` | `'default'` | Interpolation mode to apply. [See more...](../charts/line.md#cubicinterpolationmode)
+| `cubicInterpolationMode` | `string` | `'default'` | Interpolation mode to apply. [See more...](./charts/line.mdx/#cubicinterpolationmode)
| `fill` | `boolean`\|`string` | `true` | How to fill the area under the line. See [area charts](../charts/area.md#filling-modes).
| `stepped` | `boolean` | `false` | `true` to show the line as a stepped line (`tension` will be ignored).
