oSum show the sum of the values in the interval.
oMinimum shows the smallest value in the interval.
oMaximum shows the largest value in the interval.

•Set Offset to the number of rows above (if negative) or below (if positive) the current row to end each interval at.
•Set Incomplete values according to what you want to show for rows without a full interval of data. For example the first 6 rows when Interval is 7 and Offset is 0.
•Non-numeric values are ignored. E.g. a 7 day moving average that includes 2 non-numeric values will be shown as an average of the 5 numeric values.
•You will be warned of any non-numerical values in the selected column.
