+
+| Name | Type | Default | Description
+| ---- | ---- | ------- | -----------
+| `type` | `string` | | Type of scale being employed. Custom scales can be created and registered with a string key. This allows changing the type of an axis for a chart.
+| `alignToPixels` | `boolean` | `false` | Align pixel values to device pixels.
+| `backgroundColor` | [`Color`](/general/colors.md) | | Background color of the scale area.
+| `display` | `boolean`\|`string` | `true` | Controls the axis global visibility (visible when `true`, hidden when `false`). When `display: 'auto'`, the axis is visible only if at least one associated dataset is visible.
+| `grid` | `object` | | Grid line configuration. [more...](#grid-line-configuration)
+| `min` | `number` | | User defined minimum number for the scale, overrides minimum value from data. [more...](/axes/index.md#axis-range-settings)
+| `max` | `number` | | User defined maximum number for the scale, overrides maximum value from data. [more...](/axes/index.md#axis-range-settings)
+| `reverse` | `boolean` | `false` | Reverse the scale.
+| `stacked` | `boolean`\|`string` | `false` | Should the data be stacked. [more...](/axes/index.md#stacking)
+| `suggestedMax` | `number` | | Adjustment used when calculating the maximum data value. [more...](/axes/index.md#axis-range-settings)
+| `suggestedMin` | `number` | | Adjustment used when calculating the minimum data value. [more...](/axes/index.md#axis-range-settings)
+| `ticks` | `object` | | Tick configuration. [more...](/axes/index.md#tick-configuration)
+| `weight` | `number` | `0` | The weight used to sort the axis. Higher weights are further away from the chart area.

 ## Axis Range Settings
 
 Given the number of axis range settings, it is important to understand how they all interact with each other.
