Hi

still a newbye question

i try to alter the values of a dataset

series.getDataset.getValues()
returns a
java.lang.Object
(an array of string or double)

how can i manipulate these values (add values) in a chart script
so that series.getDataset.setValues(newArray) is processed

i get here an error
Error0 : Unable to process dataset content specified as
org.mozilla.javascript.NativeArray@e229be for dataset
org.eclipse.birt.chart.model.data.impl.NumberDataSetImpl@22b8ff (values:
org.mozilla.javascript.NativeArray@e229be) ( 1 time(s) )

feel free to ask for more details

thanks in advance

Laurent

Maybe you can check the Rhino syntax to create such typed arrays.
http://www.mozilla.org/rhino/ That's the engine being used in scripting.
Alternatively you can write your script in Java, so you don't have to worry
about this Java/JavaScript conversion.

Thanks,

David

i'll try, but is this also included in the .rptdesign file (so standalone)

Thanks again
