$NO-RB$ null - error

BIRTigo

Hi,

I want to show 3 line charts, using 1 table, but grouped by DateTime (like per Day, per Hour and per Minute)

All these charts were working fine the other day but now only one chart is working (per Minute) and the chart for per Day and per Hour shows this same error messages:

Chart day:
- $NO-RB$ null
null ( 1 time(s) )
