You could create another series with the following function

A1 = "No good data for this time"
B1 = if(A1="No good data for this time",NA(),A1)

Hi,
I use a 3rd party plug-in to retrieve series of time based data, among
the data, some of them are listed as "No good data for this time". As the
result, the chart plotted them as 0 (instead of leaving them blank). The
chart type is scatter.


Please help.

Thanks
