Hi,

If they are truly blank then check the plot empty cells setting via.
Select Data Hidden and Empty cells.

If the Cells in fact contain formula then use NA() instead of "". This will
suppress the data marker but will not break the line.

Alternatively use Autofilter to hide unwanted rows.

Cheers
Andy

I'm creating a line chart plot using Excel 2007. The data range for plot
lines contains some blank cells. These blank cells get plotted as zero
points.

How do I change this behavior to plot only points that have values and to
leave the blank cells unplotted?

I appreciate your help, -John
