Hello,
Simply your data must have ONLY ONE BAR - that's the reason.
You must access array elements from 0 upto (BarCount-1).
If BarCount is 1 then the only available element is element 0.
Correct code would be:
f[0]=0;
if( BarCount > 1 ) f[1]=0;
Filter=1;
NumColumns=1;
Best regards,
Tomasz Janeczko
