After that, you can choose whether you want to see data as a plain text or grid (a preview of parsed data). If you select the Plain text option, you can select Charset, but you cannot select any filter expression. Windows with results are modal, so that user can view data from components at the same time. To differ between results window title provides info about viewing edge in format GRAPH.name:COMPONENT.name.
