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.
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).
For both the `min` and `max` properties, the value must be `string` in the `labels` array or `numeric` value as an index of a label in that array. In the example below, the x axis would only display "March" through "June".
