jtsai Posted March 12, 2013 Share Posted March 12, 2013 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??ThanksJ.T.

jtsai Posted March 13, 2013 Author Share Posted March 13, 2013 It works. Since I put $V{RTN1} at property "Variable Expression" of the variable RTN1. And also variable RTN2, RTN3. Thanks J.T. Link to comment Share on other sites More sharing options...

Alex-R Posted May 17, 2013 Share Posted May 17, 2013 Can you explain how you're did it? RTNX variable is master report from? And it mapped via "Return Value" to subreport variable? Just in my case, i see mapped variable value on master report only when I place it as Text field, but not in Chart. When I select this variable in Chart and try to run report, it's fail with "Category series name is null". I've select Chart properties "Evaluation time" = Band and master (mapped) variables Calculation = System Link to comment Share on other sites More sharing options...
jtsai Posted May 21, 2013 Author Share Posted May 21, 2013 Hi Alex, In my case, the "Detail_1 section" of master report need to receive 3 return variables from a sub_report. And then show these values on "Line Chart" at "Summary section" of master report. My original problem is that the return variables(RTN1,RTN2,RTN3)show data correctly at Detail_1 section. But the "Line Chart" show nothing at Summary section. Finally, it works. Two properties of RTNx need to be set as: 1. Evaluation Time : Band 2. Text Field Expression : $V{RTN1} Link to comment Share on other sites More sharing options...
jtsai Posted May 21, 2013 Author Share Posted May 21, 2013 fail with "Category series name is null" This error show up when something wrong with Chart definition. Make sure you put the "values" not "variables" at the definitions. e.g. (of my case) 1. Series expression: "Category1" 2. Category expression: $V{MMDD} 3. Value expression: $V{RTN1} Link to comment Share on other sites More sharing options...
