/**
 * 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"
