Average Less a Month
 

I have 12 months worth of previous year's data in Excel (January-December)
but only want to graph certain months data. Not sure how to explain this. If
the current month is October, than I want to pull data from January-August;
if current month is December, than I want to pull data from January-October.
Does anyone know how I can do this with a formula? I've exhausted my limited
knowledge and not had any success.

Thank you!

Try something like this.
=sumproduct((month(a2:a22)=1)*(month(a2:a22)<mont h(today())-1)*b2:b22)

Your subject line talks of Average, but your text talks of a graph. What
are you trying to do?

I reread. Instead of sum you wanted average. Try this ARRAY formula entered
using ctrl+shift+enter
=AVERAGE(IF(MONTH(A7:A1000)1,MONTH(A7:A1000)<MONT H(TODAY()-1),D7:D1000))

I haven't had a chance to try what Don wrote yet. The 'average' data is what
is used for the graph data source. Sorry I didn't make that clear.
