/**
* Position scale x for date/time data.
*
* ## Examples
*
* - [formatting_axes_etc.ipynb](https://nbviewer.org/github/JetBrains/lets-plot-docs/blob/master/source/kotlin_examples/cookbook/formatting_axes_etc.ipynb)
*
* @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 Data range for this scale.
* A pair of values providing limits of the scale. Use `null` to refer to default min/max.
* @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 = 0.05, additive = 0.
* @param naValue Missing values will be replaced with this value.
* @param format Defines the format for labels on the scale. Also applies to `breaks`.
* @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.html](https://lets-plot.org/kotlin/formats.html)
*
* Examples:
* - "%d.%m.%y" -> "06.08.19"
* - "%B %Y" -> "August 2019"
* - "%a, %e %b %Y %H:%M:%S" -> "Tue, 6 Aug 2019 04:46:35"
