/**
* Discrete scale for x-axis.
*
* @param name The name of the scale - used as the axis label or the legend title.
* If null, the default, the name of the scale is taken from the first mapping used for that aesthetic.
* @param breaks A list of data values specifying the positions of ticks,
* or a dictionary which maps the tick labels to the breaks values.
* @param labels A list of labels on ticks, or a dictionary which maps the breaks values to the tick labels.
* @param lablim The maximum label length (in characters) before trimming is applied.
* @param limits A vector specifying values to display on the axis and their order.
* Setting limits will remove data not included in the list.
* @param expand A numeric vector of length two giving multiplicative and additive expansion constants.
* The vector size == 1 => only multiplicative expand (and additive expand by default).
* Defaults: multiplicative = 0, additive = 0.2.
* @param naValue Missing values will be replaced with this value.
* @param format Specifies the format pattern for labels on the scale.
* @param reverse When true the scale reversed.
* @param position The position of the axis:
* - "left", "right" or "both" for y-axis;
* - "top", "bottom" or "both" for x-axis.
*
* Format patterns in the `format` parameter can be just a number format (like "d") or
* a string template where number format is surrounded by curly braces: "{d} cylinders".
* Note: the "$" must be escaped as "\$".
* For more info see: [formats.md](https://github.com/JetBrains/lets-plot-kotlin/blob/master/docs/formats.md)
*
* Examples:
* - ".2f" -> "12.45"
* - "Score: {.2f}" -> "Score: 12.45"
* - "Score: {}" -> "Score: 12.454789"
