So I'm very new to formulas. I know how to create a chart that is linked to another worksheet without a problem.
What I'm looking to accomplish is to create a line chart that automatically updates when new data is entered. So if I were to enter data for October 2012 it would automatically update the chart without me having to manually select the data. I tried the OFFSET tutorials and to be totally honest I get lost so maybe can give me a step by step? Also, I only want to have 15 months of data to show on the line chart at one time. So it should show June-11 to Sept-12 to begin with and once data is entered for October (R) it should update the the line chart to show only July-11 to Oct-12.
Can somebody please give me a hand? I messed with it for about 5 hours last night and got nowhere. About 2 hours today and even watched YouTube tutorials. I can almost get the OFFSET but it's a vertical OFFSET. I tried the horizontal tutorial but it still selects vertically.
