I put a subreport at "Detail1" section, and also display 3 return values (RTN1, RTN2, RTN3) at "
Detail1" (with Evaluation time="Band"). It seems showing all RTN1~3 value at every row just fine.
But when I put a "Line Chart" at "Summery" section to show those RTN1,RTN2,RTN3 data, it allway shows empty at the chart.
Could anyone tall me why & how??
