-- Generate a graph from the given values.
-- Returns an ASS formatted vector drawing as string.

-- values: Array/Table of numbers representing the data. Used like a ring buffer
-- it will get iterated backwards `len` times starting at position `i`.
-- i : Index of the latest data value in `values`.
-- len : The length/amount of numbers in `values`.
-- v_max : The maximum number in `values`. It is used to scale all data
-- values to a range of 0 to `v_max`.
-- scale : A value that will be multiplied with all data values.
