Dynamic Query expression with BIRT Chart

Hi,
I'm trying to set a dynamic query expression in a Line chart that I'm designing using BIRT. I would appreciate any help on this.

My problem:
I would like to set a filter condition to my pre-created dataset to filter the records of my second column (cols[2]) based on the filter condition on the first column (cols[0]). Here's the piece of code I'm using.

// X series
Series xCategory = SeriesImpl.create();
xCategory.getDataDefinition().add(QueryImpl.create("row[\"" + cols[0] + "\"]"));

// Y series
LineSeries yCategory = (LineSeries) LineSeriesImpl.create();
Query fileUploadQuery = QueryImpl.create("row[\"" + cols[2] + "\"]" );
yCategory.getDataDefinition().add(fileUploadQuery);

I would also like to remove any duplicate row from the first column (cols[0]).

Thanks in advance for the help.

Is there a reason you couldn't just do the filtering on the dataset itself, or drop it in a table? What version of BIRT are you using? In the 2.5 and 2.6 series, there is a filter option in the Data Editor tab.
