Creating a chart in Excel that ignores #N/A or blank cells

Question

I am attempting to create a chart with a dynamic data series. Each series in the chart comes from an absolute range, but only a certain amount of that range may have data, a

I was having the same issue by using an IF statement to return an unwanted value to "", and the chart would do as you described.

However, when I used #N/A instead of "" (important, note that it's without the quotation marks as in #N/A and not "#N/A"), the chart ignored the invalid data. I even tried putting in an invalid FALSE statement and it worked the same, the only difference was #NAME? returned as the error in the cell instead of #N/A. I will use a made up IF statement to show you what I mean:

=IF(A1>A2,A3,"")  
---> Returned "" into cell when statement is FALSE and plotted on chart 
     (this is unwanted as you described)

=IF(A1>A2,A3,"#N/A")  
---> Returned #N/A as text when statement is FALSE and plotted on chart 
     (this is also unwanted as you described)

=IF(A1>A2,A3,#N/A)  
---> Returned #N/A as Error when statement is FALSE and does not plot on chart (Ideal)

=IF(A1>A2,A3,a)  
---> Returned #NAME? as Error when statement is FALSE and does not plot on chart 
    (Ideal, and this is because any letter without quotations is not a valid statement)
