[How to create a Dotter Graph with multiples column values]

Hi,

I want to know if I can create a Bean like: List<Object, List<Object>> and pass it to a report, to show a Dotter graph where I have multiple column values,

The thing is that the secon List can have 2 or more elements and I don't know on runtime!

like this:

 

	Value 1	Value 2	Value 3	Value 4	Value 5
Serie 1	100	80	100	180	100
Serie 2	100	100	80	80	70
Serie 3

And, in other time I only need value 1 and value 2

and in other time could be 20 Value commands.

 

I'm using eclipse rcp, with Jasper Reports 4.1.2.

I know is old, but i need it !

This is a sample on how I pass data to the reports

            Map<Object, Object> parameters = new HashMap<Object, Object>();
            parameters.put("anio", anio.getAnio());
            parameters.put("logo", "/images/logo.jpg");
            parameters.put("filial", filial);
            parameters.put("f", cruzas.get(0).getFilial());        //Tomo Primer Filial    
            
            List<CruzaDTO> contenido = generarContenido(cruzas, filial);
            JRBeanCollectionDataSource ds = new JRBeanCollectionDataSource(contenido);
            JasperReport report = (JasperReport) JRLoader.loadObject(FilialesReportGenerator.class.getClassLoader().getResourceAsStream("reportes/FilialesLibro.jasper"));
            print = JasperFillManager.fillReport(report, parameters, ds);
 

 

Thanks

[HOW to Create Series in Line Chart on the fly.]

 Hi, I have a SQL query that si a sort of PIVOT table, like sales by person and period query.

The common problem is that I don't know how many sales-persons do I have at some time.

so the query should have some fixed columns as id and period, and some variabe columns as persons !

Is design mode the report looks great,

but what appends when I run this on the real application ?

I want to know if there is a way for creating series in the report on the fly ?

I'm using .jasper files, so the report is compiled when i use it on the application.

 

Best Regards

[How Jasper process parameters to show on reports as fields ! (newby)]

is an object, but the las one (ds) is the datasource !! so there is the detail !

 

Although teh repòrt compile, my questin still activo for the issue about classpath ...

 

 

[How Jasper process parameters to show on reports as fields ! (newby)]

 Hy, I'm quite newby to Jasper Report,

I'm upgrading an application that was developed a few years ago.

So I'm upgrading som reports.

I'm working with an old version of library (2.0.3) and iReport (2.05).

My question is, the report has a parameter that is an Object of mi application, so the DataSource is allway an object, never gos to the database directly.

That object got a property that is a List.

@Entity@Table(name="Ensayos")public class Ensayo implements Cloneable {	private Integer id;	private Integer anio;	private String epoca;	private String nombre = new String();	private String descripcion = new String();	private Date fechaSiembra;	//private Localidad localidad = null;	private String localidad;	private Integer cantidadCruzas;	private Integer cantidadRepeticiones;	private Integer parcela;	private List repeticiones = null;	private Date fechaCreacion = null;	private Date fechaImportacion = null;	private Date fechaExportacion = null;	private Date ultimaModificacion = null;	private boolean activo = true;	private boolean replicado = false;	//private boolean realeatorizado = false;	//private Integer cantidadTestigos;	private boolean seleccionada = false;}

So, in the detail section I have a lot of Fields, that use attributes of object

for example; 

    $F{peso}[/code]

So my question is:

how jasper know how to map report field $F{peso} to the attribute peso in Repeticion class ?

And anoter issue that I have is that althoug I add the bin folder, root folder an model folder to the menu option: Options->ClassPath, I allway get the error on design that the class ar.com.cse.balanza.model.Ensayo is not found !

Any help will be appreciated.

Best regards

Nicolas
