Class ScriptColumn

column combiner which uses a custom JavaScript function to combined the values The script itself can be any valid JavaScript code. It will be embedded in a function. Therefore the last statement has to return a value.

In case of a single line statement the code piece statement return will be automatically prefixed.

The function signature is:
any, index: number, children: Column[], values: any[], raws: (number|null)[]) => number

param: ```: the row in the dataset to compute the value for
param: ``: the index of the row
param: `code>: the list of LineUp columns that are part of this ScriptColumn
param: `values`: the computed value of each column (see `children`) for the current row
param: `raws`: similar to `values`. Numeric columns return by default the normalized value, this array gives access to the original "raw" values before mapping is applied
returns:: the computed number in the range [0, 1] or NaN

In addition to the standard JavaScript functions and objects (Math, ...) a couple of utility functions are available:

`max(arr: number[]) => number`: computes the maximum of the given array of numbers
`min(arr: number[]) => number`: computes the minimum of the given array of numbers
`extent(arr: number[]) => [number, number]`: computes both minimum and maximum and returning an array with the first element the minimum and the second the maximum
`clamp(v: number, min: number, max: number) => number`: ensures that the given value is within the given min/max value
`normalize(v: number, min: number, max: number) => number`: normalizes the given value `(v - min) / (max - min)`
`denormalize(v: number, min: number, max: number) => number`: inverts a normalized value `v * (max - min) + min`
`linear(v: number, input: [number, number], output: [number, number]) => number`: performs a linear mapping from input domain to output domain both given as an array of [min, max] values. `denormalize(normalize(v, input[0], input[1]), output[0], output[1])`
