problem in stdev

[#1]

Hi All,

In attached app when i was selecting only single value in "MonthYear" listbox, then in straight table chart "Stdev" expression is getting '-' value.

How i can resolve this issue and should get the value instead of '-'?

please provide your suggestion on this from anyone

Regards,

Hi Satish,

the fact is that RangeStdev of a single value is zero, or rather is not calculated, cause the value is equal to its avg.

I think you'd like to see '0' rather than '-'... well, I would do it brutally: if(rowno()=1,0,expr).
