/**
* A waterfall plot shows the cumulative effect of sequentially introduced positive or negative values.
*
* ## Notes
*
* Computed variables:
*
* - ..x.. : category id.
* - ..xlabel.. : category name.
* - ..ymin.. : lower value of the change.
* - ..ymax.. : upper value of the change.
* - ..measure.. : kind of a calculation: absolute, relative or total.
* - ..flow_type.. : direction of the flow: increasing, decreasing, or the result (total).
* - ..initial.. : initial value of the change.
* - ..value.. : current cumsum (result of the change) or absolute value (depending on the "measure" column).
* - ..dy.. : value of the change.
*
* ## Examples
*
* - [waterfall_plot.ipynb](https://nbviewer.org/github/JetBrains/lets-plot-docs/blob/master/source/kotlin_examples/cookbook/waterfall_plot.ipynb)
*
* @param data The data to be displayed in this layer.
* @param x Name of a variable.
* @param y Name of a numeric variable.
* @param measure Kind of a calculation.
* Values in 'measure' column could be:
* - "absolute" - the value is shown as is;
* - "relative" - the value is shown as a difference from the previous value;
* - "total" - the value is shown as a cumulative sum of all previous values.
*
* @param group Grouping variable.
* Each group calculates its own statistics.
* @param color Color of the box boundary lines.
* For more info see: [aesthetics.html#color-and-fill](https://lets-plot.org/kotlin/aesthetics.html#color-and-fill).
* Use "flow_type" to color lines by the direction of the flow.
* @param fill Fill color of the boxes.
* For more info see: [aesthetics.html#color-and-fill](https://lets-plot.org/kotlin/aesthetics.html#color-and-fill).
* Use "flow_type" to color boxes by the direction of the flow.
* @param size default = 0.0.
* Line width of the box boundary lines.
* @param alpha Transparency level of the boxes. Understands numbers between 0 and 1.
* @param linetype Int or String or List or Pair.
* Type of the box boundary lines.
* Accept codes or names (0 = "blank", 1 = "solid", 2 = "dashed", 3 = "dotted", 4 = "dotdash", 5 = "longdash", 6 = "twodash"),
* a hex string (up to 8 digits for dash-gap lengths),
* or a pattern `offset to listOf(dash, gap, ...)` / `listOf(dash, gap, ...)`.
* For more info see: [aesthetics.html#line-types](https://lets-plot.org/kotlin/aesthetics.html#line-types).
* @param width default = 0.9.
* Width of the boxes. Typically range between 0 and 1.
* Values that are greater than 1 lead to overlapping of the boxes.
* @param showLegend default = false.
* true - show the legend.
* @param relativeTooltips Result of the call to the `layerTooltips()` function.
* Tooltips for boxes with relative values.
* Specifies appearance, style and content.
* When "none", tooltips are not shown.
* When "detailed", a more detailed (compared to the default) version of the tooltips is shown.
* @param absoluteTooltips Result of the call to the `layerTooltips()` function.
* Tooltips for boxes with absolute values.
* Specifies appearance, style and content.
* When "none", tooltips are not shown.
* When "detailed", a more detailed (compared to the default) version of the tooltips is shown.
* @param base default = 0.0.
* Values with measure "absolute" or "total" are relative to this value.
* @param sortedValue default = false.
* Sorts categories by absolute value of the changes.
* @param threshold Groups all categories under a certain threshold value into "Other" category.
* @param maxValues Groups all categories with the smallest changes, except the first `maxValues`, into "Other" category.
* @param calcTotal default = true.
* Setting the `calcTotal` to true will put the final cumulative sum into a new separate box.
* Taken into account only if the "measure" column isn't provided.
* @param totalTitle The header of the last box with the final cumulative sum, if "measure" column isn't provided.
* Also used as a title in the legend for columns of type "total".
* @param hline Horizontal line passing through 0.
* Set "blank" or result of `elementBlank()` to draw nothing.
* Set `elementLine()` to specify parameters.
* @param hlineOntop default = true.
* Option to place horizontal line over the other layers.
* @param connector Line between neighbouring boxes connecting the end of the previous box and the beginning of the next box.
* Set "blank" or result of `elementBlank()` to draw nothing.
* Set `elementLine()` to specify parameters.
* @param label Label on the box.
* Shows change value.
* Set "blank" or result of `elementBlank()` to draw nothing.
* Set `elementText()` to specify parameters.
* Use "flow_type" for `color` parameter of the `elementText()` to color labels by the direction of the flow.
* @param labelFormat Format used to transform label mapping values to a string.
* For more info see: [formats.html](https://lets-plot.org/kotlin/formats.html)
* Note: the "$" must be escaped as "\$".
*
* Examples:
* - ".2f" -> "12.45"
* - "Score: {.2f}" -> "Score: 12.45"
* - "Score: {}" -> "Score: 12.454789"
