Chart linking with Name Manager

HelloAbdulrahim-tu​ 

You’re right that `OFFSET` works best when you have a starting cell and a length, but it doesn’t directly handle “start at row X and end at row Y.” That’s why you’re seeing duplication when you try to use beginning and ending limits.

For chart ranges where both the start and end are dynamic, `INDEX` is the better function. You can define the range like this:

=INDEX('Study'!$F:$F,'Study'!$BC$26):INDEX('Study'!$F:$F,'Study'!$BD$26)

• `INDEX('Study'!$F:$F,'Study'!$BC$26)` → returns the starting cell in column F, based on the row number in cell BC26.
• `INDEX('Study'!$F:$F,'Study'!$BD$26)` → returns the ending cell in column F, based on the row number in cell BD26.
• The colon (`:`) creates a proper range between those two cells.

So if BC26 = 100 and BD26 = 300, the formula resolves to:

=F100:F300

This way, your chart series will only plot values between the start and end limits, without duplication.

Steps to apply:

1. Go to Formulas > Name Manager.
2. Create a new name (e.g., `ChartRange`).
3. In the “Refers to” box, paste the formula above.
4. Use `ChartRange` as the series values in your chart.

This approach avoids the pitfalls of `OFFSET` and gives you a clean dynamic range that respects both start and end limits.
