You can optionally include a parameter which references an existing filter in another Dashlet, and uses that filter to display a specific web page relevant to the filtered information.
Right-click the dashboard name and select Open in Designer from the context menu. The Dashboard Designer opens.

Click Enable chart hyperlinks to select it.
Choose Open new page from the Action menu.
The Web Address/Repository URL entry bar is displayed.
