Replace the blank by #N/A
So let's say your formula is =IF(this-test, B2,"") then use
=IF(this-test,B2,NA())
When the test fails, this displays #N/A which the chart engine ignores
If this looks odd in a print out, use a conditional format such as =ISNA(C2)
and make the font the same as the cell background - make it invisible on the
screen and then printed.

Hi,

In a chart I have a formula that either returns a number or "" in a cell.
I
then have a dynamic range set which plots the values on a graph. The
problem
is that the chart will plot the ""s as zeros as it sees something in the
cell.

Is there a way I can have a true blank cell result coming from a formula?

If not how I can avoid the dynamic range seeing this as a zero?

Thanks
