The Indices DAT creates a series of numbers in a table, ranging between the start and end values. These values are suitable for display along a graph horizontal or vertical axis. They are carefully picked to make them all round, nicely spaced, etc.
/start - the start of the number range.
/end - the end of the number range.
/level - determines how the range is divided. Coarse = 0, Medium = 1, Fine = 2
/origin - the first number in the series.
