The linear scale is used to chart numerical data. It can be placed on either the x or y-axis. The scatter chart type automatically configures a line chart to use one of these scales for the x-axis. As the name suggests, linear interpolation is used to determine where a value lies on the axis.
| `grace` | `number`\|`string` | Percentage (string ending with `%`) or amount (number) for added room in the scale range above and below data. [more...](#grace)
| Name | Type | Scriptable | Default | Description
| ---- | ---- | ------- | ------- | -----------
| `count` | `number` | Yes | `undefined` | The number of ticks to generate. If specified, this overrides the automatic generation.
| `format` | `object` | Yes | | The [`Intl.NumberFormat`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Intl/NumberFormat) options used by the default label formatter
| `maxTicksLimit` | `number` | Yes | `11` | Maximum number of ticks and gridlines to show.
| `precision` | `number` | Yes | | if defined and `stepSize` is not specified, the step size will be rounded to this many decimal places.
| `stepSize` | `number` | Yes | | User-defined fixed step size for the scale. [more...](#step-size)
If set, the scale ticks will be enumerated by multiple of `stepSize`, having one tick per increment. If not set, the ticks are labeled automatically using the nice numbers algorithm.
This example sets up a chart with a y axis that creates ticks at `0, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5`.
The value is added to the maximum data value and subtracted from the minimum data. This extends the scale range as if the data values were that much greater.
