Nicolas,

=IF(condition,1,NA())

The NA() will be ignored by your chart.

I am looking for a function that leaves a cell blank.
I am using now a function like: IF(condition,=1,""). So that if hte
condition is not fulfilled the cell remains blank (as it was before).
The problem is that "" is different than a blank cell! When you make some
chart excel takes "" as a zero value, but skips the blank cells.

Can anyone help? Thanks in advance.
