Option 1: Replace the "" in your formula with NA().

Option 2: If you don't like the ugly #N/A or it messes up downstream
calculations, use another column in which you have the NA() instead of
the "". Plot this new column but use the original for other work.

Option 3: Adapt the ideas behind

If you use COUNT() instead of COUNTA(), the solution will include only
those cells with numbers and exclude the ""s.

Have you found the answer yet?
I am trying to plot a data series also through months. If the month is not
here yet, the cell is calculated to be blank, but the chart is plotting it as
zero. Is this similar to your situation? How did you fix it?
Thanks

My Data Series contains blanks as the result of formula calculations. The
location and number of blanks can change with each recalculation as input
criteria change. I can make my Chart ignore an "Empty" cell easy enough but
my cells still contain the formula which created the blank ("") cell and
therefore, not truely empty. I want to plot the series, about 7000 values,
without the blanks showing up as zeros and ruining my trendline fit.
Removing those rows is not an option as I have to retain the x-axis value as
place holder on the chart.

Thanks for your help; nothing is as simple as it seems when you start
