Hi Giulio, Thank you very much for your help - my charts have data in them! I had to add the Code:, new Boolean (true), AND set compatibility options to JasperReports 1.2.0 before it would work. Now for the next questions... The catch date is datatype varchar2 (6) because I have to group historic data by month & day, no year. I need the catch date on the category axis and I get the following compile error: CannotÂcastÂfromÂStringÂtoÂNumber valueÂ=Â(java.lang.Number)(((java.lang.String)field_CATCH_DATE.getValue())); Also, what is the syntax for adding two fields to the series expression? I need to show points for historic data and current year harvest data. Thanks very much for your time and help! - Martina
