I am trying to graph a weighted moving average. I need the graph to show 12 months of history. With every new month (column) I add to the right off the data, I need the graph to drop the month's data from 13 month ago. I think I am close, but no cigar yet.
Example Included Graph test.xls
Here are my defined Names:
Date2=OFFSET(Sheet1!$B$2,0,0,1,COUNTA(Sheet1!$2:$2)-1)
Sales2=OFFSET(Sheet1!$B$3,0,0,1,COUNTA(Sheet1!$2:$2)-1)
Here is my current graph series equation:
=SERIES(Sheet1!$A$3,'Graph Test.xls'!Date2,'Graph Test.xls'!Sales2,1)
I thought there may be some way to use the address function, but It keeps giving me an error. I trie both as a defined name and jut in th regular equation.
=SERIES('Graph Test.xls'!(ADDRESS(3,(COUNT($3:$3))-12)),'Graph Test.xls'!Date2,'Book3 (version 1).xls'!Sales2,1)
Can you help?
thanks
Sadler
