# Category Cartesian Axis
If global configuration is used, labels are drawn from one of the label arrays included in the chart data. If only `data.labels` is defined, this will be used. If `data.xLabels` is defined and the axis is horizontal, this will be used. Similarly, if `data.yLabels` is defined and the axis is vertical, this property will be used. Using both `xLabels` and `yLabels` together can create a chart that uses strings for both the X and Y axes.
Specifying any of the settings above defines the x axis as `type: 'category'` if not defined otherwise. For more fine-grained control of category labels it is also possible to add `labels` as part of the category axis definition. Doing so does not apply the global defaults.
## Category Axis Definition
Globally:
```javascript
let chart = new Chart(ctx, {
type: ...
data: {
labels: ['January', 'February', 'March', 'April', 'May', 'June'],
datasets: ...
}
});
```
As part of axis definition:
```javascript
let chart = new Chart(ctx, {
type: ...
data: ...
options: {
scales: {
xAxes: [{
type: 'category',
labels: ['January', 'February', 'March', 'April', 'May', 'June']
}]
}
}
});
```
## Tick Configuration Options
The category scale provides the following options for configuring tick marks. They are nested in the `ticks` sub object. These options extend the [common tick configuration](README.md#tick-configuration).
| Name | Type | Default | Description
| ---- | ---- | ------- | -----------
| `labels` | `string[]` | - | An array of labels to display.
| `min` | `string` | | The minimum item to display. [more...](#min-max-configuration)
| `max` | `string` | | The maximum item to display. [more...](#min-max-configuration)
## Min Max Configuration
For both the `min` and `max` properties, the value must be in the `labels` array. In the example below, the x axis would only display "March" through "June".
```javascript
let chart = new Chart(ctx, {
type: 'line',
data: {
datasets: [{
data: [10, 20, 30, 40, 50, 60]
}],
labels: ['January', 'February', 'March', 'April', 'May', 'June']
},
options: {
scales: {
xAxes: [{
ticks: {
min: 'March'
}
}]
}
}
});
```
