If the cells are truly blanks, try Tools menu > Options > Chart tab >
Show blank cells as... Not Plotted.

=IF(A1>0,A1,NA())
The NA() produces an ugly #N/A error in the sheet, but in line and
scatter charts they aren't plotted. Debra Dalgleish shows how to hide
the errors with conditional formatting:
