A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Sparklines can only reference ranges, so you will need to create another table that includes formulas to pull the latest data so that the sparkline will update.
For example, if your table is in A:I, then this formula:
=VLOOKUP(LARGE($A:$A,8-ROW(A1)),$A:$I,COLUMN(A1),FALSE)
copied down for 7 rows and across for 9 columns - will pull the latest data and allow the sparklines to update.
