Jaspersoft Studio / Pie Charts

[unficyp]

Hi,

tried to create a pie chart using this tutorial (http://community.jaspersoft.com/wiki/creating-charts-and-datasets-jaspersoft-studio)

but with my own dataset using this query:

select status_name label,  count(*) value from v_project_detail group by status_name[/code]

 

the "Data preview" in the Dataset and Query Dialog shows the correct data but the Charts shows only "Document empty"

after clicking on preview.

In the chart i put 

Value -> $F{VALUE}

Label -> $F{LABEL}

Key -> $F{LABEL}

Max slices to Show 10

 

Console Output:

Start Report Execution

Compiling report......DONE

StartingSetting Data Adapter...DONE

Setting Virtualizer...DONE

Filling Report........DONE

Report Execution Finished.

 

No errors.

 

How can i find out whats wrong ?

 

thnanks & regards

gerald

Hi,

it seems that the report main query does not return data. That is why you get empty document.

Try to specify a dummy SQL for the report main query or setup When No Data Type report property to 'All Sections No Detail'

No Report Main Query !

Thats the problem - fixed now - thanks !
