I have some flex' app, which draw me a chart based on some outside
xml. My app looks like on this tutorial:
http://dev.base86.com/solo/25/flex_2_charting_with_xml_tutorial.html

Everything works fine, but now I'd like to add one more action (go to
some URL after click on some column)?

I would like to have one more tag (<url> for example) in all 'row'
tags and then go to url from this tag after click on column which is
represented by this row.

could anyone please help with that?
