culture? string

The culture to use when formatting date values.
The specified culture must be loaded as demonstrated in the Internationalization Overview.

The format for displaying the labels of the date category axis.
The {0} placeholder represents the category value.
The Chart selects the appropriate format for the current categoryAxis.baseUnit option.
Setting the categoryAxis.labels.format option overrides the date formats.
For more information, refer to the format method of IntlService.

margin? Margin | number

The margin of the labels. A numeric value sets all margins.

left side of the axis, the mirroring of the axis renders them to the right.

The padding of the labels. A numeric value sets all paddings.

position AxisLabelsPosition

The position of the axis labels. By default, labels are positioned next to the axis.
