A foolproof way to define dynamic named ranges is to use OFFSET().



E.g.where
AnchorPoint is address of some single cell which you are sure it will never be deleted, and is above or in same row as the range you want to define, and left or in same column as the range you want to define;
RowsDown is the number of rows from AnchorPoint to topmost row of range you want to define;
ColumnsRight is the number of columns from AnchorPoint to leftmost column of range you want to define;
NumberOfRows is the number of rows you want in defined range;
NumberOfColumns is the number of columns you want in defined range.

E.g. you want to define a range P5:P1, anchored to cell P1:
To make the range dynamic, you have to replace at least one of parameters to be calculated by formula.

To get any detailed help you have to attach some example table here.

Thank you for your help! Yes, my formulas already had offset in them for the columns of data dependent on the original dynamic array. And according to the spilled data, they were working perfectly. I think I was having trouble describing my issue, and I was going to clean up an example to upload and I think finally solved my own problem, so I think you're partly responsible.

My trouble was getting the chart to "read" or accept the named range. Finally tried making all of the named ranges under the scope "Worksheet" rather than the default, "Workbook." And with that, the chart is finally working properly.

I'm going to go back and try again, creating the named ranges on "Workbook" scope but apparently the one thing that maybe I was missing initially was ='SHEETNAME'! before my named range in the chart. I could have sworn the example I watched on a video didn't have that detail.

Thank you,

Ann
