Omitting zeros from chart for future dates/formula in use...

I currently have a chart for complaints & returns, however, future days/months are coming up zero on the chart.

Formula in use for cells is (one example): =COUNTIF(COMPLAINTS.xlsx!$A$2:$A$24,"3/25/2013")

Is there anything else I can add/use to omit these future zeros from showing on the line graph?

Thanks!

There is ways around the zeros via formulas, but a pivot chart will probably do what you want easier.
Try pivot chart add and select your data to see how it can display the data in the chart.
