Can I avoid plotting 'non-empty' cells

Hi
I am plotting data such as the following on a simple line chart...

Jan Feb Mar Apr May June
10 11 12 0 0 0

The future month (Apr, May , June) each contain a formula which returns either zero or "" as no data is available.

The problem is that I don't want the future months to be plotted as zero, which is what happens. There is an option in Excel to avoid plotting 'empty' cells - but these cells are not empty as they contain a formula.

Of course, I could simply choose Jan:Mar as the chart range and update it each month, but I know I'll forget to do it. Alternatively, I could delete the formula and paste them in each month, but that's still relying on me to remember.

Thanks

Here is a link to a post that I have on handling missing data.

In your If formula, replace your "" with NA(). This will place a #N/A in
your future cells. Excel recognizes #N/A and will not plot them. that should
solve your problem.

Bernard Liengme also has a post on handling missing data..
