show only one record in a chart

[geogou1973]

Hello.

I'm facing a problem in a chart.

I have a field of tax code  60911 and this code has two barcodes 123456789012 and 987654321098 and the sales.

How can i show in the chart only the one barcode. I don't care which of the two ?

Can anyone help me ?

Thank you in advance.
