guessYTagWidth

guessYTagWidth( org.das2.dataset.TableDataSet table, int itable ) → Datum

guess the y tag cadence by returning the difference of the first two tags. If the tags appear to be log spaced, then a ratiometric unit (e.g. percentIncrease) is returned. monotonically decreasing is handled, in which case a positive tag cadence is returned.
